Business Intelligence and Analytics A Comprehensive Overview Jack G. Zheng Fall 2018 (since V1 2012) http://jackzheng.net/teaching/it6713/ https://www.edocr.com/v/r4dg6mjr/ IT 6713 BI Overview What is business intelligence (BI) and analytics? BI/Analytics as an information and decision process BI/Analytics as an information system BI/Analytics process Data, information, decision BI/Analytics systems and tools Values, capabilities, and components Technologies, architectures, platforms Application areas Products, industries, and markets BI evolution and trend: traditional BI and modern BI BI/Analytics learning and career 2 Types of Information Processing Transactional Processing Focus on individual data item processing: data insertion, modification, deletion, transmission, and non- analytical query Analytical Processing Focus on reporting, analysis, transformation, and decision support 3 http://www.slideshare.net/fmhyudin/oltp-vs-olap-23317601 Change product price Increase customer credit limit Who has not paid bills? DIKW Data: raw value elements or facts Information: the result of collecting and organizing data that provides context and meaning Knowledge: the concept of understanding information that provides insight to information, thus useful and actionable http://en.wikipedia.org/wiki/DIKW_Pyramid 4 Transactional Processing Analytical Processing Examples of Analysis Non-analytical query (listing) Get a list of students enrolled in in the IT 6713 class. Descriptive analysis (summarizing) How many students are enrolled in online IT graduate courses for the past year? What if analysis If inventory levels are reduced by 10%, what is the new cost of inventory storage? Reasoning and correlation What is the reason for a decrease of total sales this year? How do advertising activities affect sales of different products bought by different type of customers, in different regions? (synthesizing) Fuzzy decision support What new advertising strategies need to be undertaken to reach our customers who can afford a high priced product? Should we invest more on our e-business? 5 What is Business Intelligence? Business Intelligence is a set of methods, processes, architectures, applications, and technologies that gather and transform raw data into meaningful and useful information used to enable more effective strategic, tactical, and operational insights and decision-making. 6 Adapted from Forrester Report "Topic Overview: Business Intelligence", 2008 https://www.forrester.com/report/Topic+Overview+Business+Intelligence/-/E-RES39218 More BI from Forrester https://www.forrester.com/business-intelligence Data Types of data Numeric vs. textual Structured vs. unstructured Standard format vs. proprietary format Internal vs. external data, system stored vs. file based data Raw fact data vs. simulated/forecast/estimated data Simple fact data vs. calculated metrics data Common data problems Big data Variety, Velocity, Volume, Veracity https://www.ibmbigdatahub.com/infographic/four-vs-big-data Structured, unstructured, semi-structured Information and knowledge management is the management of both structured data (15% of information) and unstructured data (85% of information), according to the Butler Group. 80 percent of business is conducted on unstructured information (Gartner Group). Different data sources Over 43 percent of organizations have more than six content stores. (Forrester Research). Don't have that data The data is simply not available. The collection of data may need additional process and is costly. Information overloading too much data and information with varied formats and structure difficulty of data organization for effective access and retrieval difficult to find useful information (knowledge) from them Data everywhere Data in separate systems and different sources; internal and external Problem of spreadmart http://en.wikipedia.org/wiki/Spreadmart Difficulty of access We may have that data but we cannot access it (or difficult to get it), because of technical issues or administrative issues. 7 Decision Making Decisions can be made based on Facts, or data Simulation (models) Intuition, perception, sense Group negotiation Traditionally BI has been also understood as Decision Support System (DSS) known as data driven DSS (data directly contributes to decision without intensive and advanced analytical techniques). A brief history of DSS: http://dssresources.com/history/dsshistory.html Problem A gap between data and knowledge (useful information leading to a decision). Management/operation by intuition Lack of effective feedback and alignment systems, no improvement cycles Need good analytical processing and models Evolving analytical needs Real-time, most recent data Business user driven, agile, instant Exploratory and interactive 8 Additional Notes about BI BI is the an umbrella term for a set of methods, processes, applications, and technologies used to gather, provide access to, analyze, and report data and information support understanding and decision making A common goal in BI is to drive performance The evolution of BI resides both in "business" and "intelligence" The term "business" is more general and represents the application domain; not just related to profit driven businesses. Traditionally BI is related to business or corporate operations, but can also extend to other types of organizational contexts, like non-profits, governments, institutions, etc. Intelligence represents the resource and the techniques or methods Narrowly speaking, intelligence comes from data (facts). Traditional BI normally does not directly address other content types and formats (which usually falls under artificial intelligence). In this sense, BI focuses on analytical data processing. Broadly speaking, intelligence, or knowledge, comes from human experience and tacit knowledge, in various format like text, image, video, etc. In this sense, BI is also related to knowledge management (either BI under KM or vice versa) http://capstone.geoffreyanderson.net/export/19/trunk/proposal/research/Knowledge_mana gement.pdf 9 Evolution of BI The search for the perfect "business insight system", from Performance Dashboard, by Wayne Eckerson, http://download.101com.com/pub/tdwi/files/performancedashboards.pdf 10 1980s Executive information systems (EIS), decision support systems (DSS) 1990s Data warehousing (DW), business intelligence (BI) 2000s Dashboards and scorecards, performance management 2010+?? Analytics, big data, personal BI, data science, augmented BI, "With each new iteration, capabilities increased as enterprises grew ever-more sophisticated in their computational and analytical needs and as computer hardware and software matured." Solomon Negash (2004), Business Intelligence, CAIS (13) https://www.researchgate.net/publication/228765967_Business_intelligence Analytics Analytics has emerged as a catch-all term for a variety of different business intelligence (BI) and application-related initiatives. Whatever the use cases, "analytics" has moved deeper into the business vernacular. https://www.gartner.com/it-glossary/analytics/ Analytics refers to a more systematical, automated, and flexible process of data analysis for revealing insights and decision support in more extensive application areas, e.g. sports, disease, network traffic, etc. http://pestleanalysis.com/differences- between-business-analytics-and-business- analysis/ Analytics initially referred to advanced statistical modeling using tools like SAS and SPSS. Now, analytics refers to the entire domain of leveraging information to make smarter decisions. In other words, reporting and analysis. The Evolution of BI Semantics http://www.b- eye- network.com/blogs/eckerson/archives/2011/0 2/whats_in_a_word.php 11 The Evolution of BI Semantics http://www.b-eye- network.com/blogs/eckerson/archives/2011/02/whats_i n_a_word.php Analytics can be viewed as the evolved or improved BI BI and Other Related Terms Big data "Big Data is not a system; it is simply a way to say that you have a lot of data. https://www.linkedin.com/pulse/big-data-silver-bullet-tomas-kratky Big data covers non-structure and various data formats including text, blob, multimedia, etc. Data science An interdisciplinary field about processes and systems to extract knowledge or insights from data in various forms Focus on analysis and presentation models and methods A good data scientist = data hacker + programmer+ analyst+ coach+ story teller+ artist (http://analyticsindiamag.com/data-science-the-most-desirable-job-in-the-21st-century/) "In some ways, data science is an evolution of BI." https://www.linkedin.com/pulse/data-science- business-intelligence-whats-difference-david-rostcheck/ All these new terms try to differentiate them from the (traditional) BI. However, if one considers BI is a dynamic and evolving field, then all these new terms are just extensions/expansions of BI; they all still fall under the umbrella of the general BI. "In its more comprehensive usage, BI is all of the systems, platforms, software, technology, and techniques that are essential for the collection, storage, retrieval, and analysis of data assets within a given organization." Dataversity 2015 Report on BI vs Data Science More perspectives https://solutionsreview.com/business-intelligence/data-science-vs-data-analytics-whats-the-difference/ http://www.dataversity.net/distinguishing-analytics-business-intelligence-data-science/ https://www.betterbuys.com/bi/business-intelligence-vs-business-analytics/ 12 BI: A General Process 13 Results are presented and delivered in different human comprehendible formats, to support decisions. It also includes data exploration and reporting. The organization and transformation of data into clean and common models and formats. The collection of raw data from different sources by different means, and in different formats. Data Gathering Data Cleanse Data Analysis Data Presentation Data Storage The refined data will be modeled (if needed) and stored in a particular place (e.g., a file or a data management system) and ready for analysis. The process involves analytical components, such as dimensional analysis, statistical analysis, business analytics, and data mining, to extract information and knowledge. Queries can also directly present results to users without intensive analysis. This is usually used for data exploration and descriptive reports. Data Preparation BI in the Decision Process Another view from the business decision perspective http://www.slideshare.net/junesungpark/business-process-based-analytics 14 BI Capabilities 15 Figure from: Business Intelligence, Rajiv Sabherwal, Irma Becerra-Fernandez, John Wiley & Sons, 2011 http://books.google.com/books?id=T-JvPdEcm0oC This is consistent with the general BI or analytics process but more from an information behavior angle. (Enterprise) BI Systems A BI system is a computer information system that implements (part or whole) BI capabilities and processes The value of BI Systems Provide an integrated data (analytical) processing platform Enable easy and fast access of data and information at all levels (raw data, analysis results, metrics, etc.) Streamline a controlled and managed process of data driven decision making 16 Query OLAP Business analytics Statistics Data mining Text mining Advanced analytics BI System (Components) at a Glance 17 Reports Data visualization Dashboard Scorecards Strategy map Visual analytics Performance management Benchmarking Market research CRM Strategic management Web site analytics Relational database Data warehouse Data lake Data modeling Data governance Data integration ETL Data quality Metadata Master Data Data virtualization Data Storage and Management Analytical Processing Presentation Applications Local files Website Reporting server Application server BI server Portal Excel services Delivery Users with applications (browser, desktop app, mobile app, email, etc.) and devices (computer, tablet, phone, print- outs, etc.) Critical Capabilities of a BI and Analytics Platform Infrastructure BI Platform Administration. Capabilities that enable scaling the platform, optimizing performance and ensuring high availability and disaster recovery. Cloud BI. Platform-as-a-service and analytic-application-as-a-service capabilities for building, deploying and managing analytics and analytic applications in the cloud, based on data both in the cloud and on-premises. Data Source Connectivity. Capabilities that allow users to connect to the data contained within various types of storage platforms. Data Management Governance and Metadata Management. Tools for enabling users to share the same systems-of-record semantic model and metadata. These should provide a robust and centralized way for administrators to search, capture, store, reuse and publish metadata objects, such as dimensions, hierarchies, measures, performance metrics/key performance indicators (KPIs) and report layout objects, parameters and so on. Self-Contained ETL and Data Storage. Platform capabilities for accessing, integrating, transforming and loading data into a self-contained storage layer, with the ability to index data and manage data loads and refresh scheduling. Self-Service Data Preparation. The drag-and-drop, user-driven data combination of different sources, and the creation of analytic models such as user-defined measures, sets, groups and hierarchies. Scalability and Data Model Complexity. The degree to which the in-memory engine or in database architecture handles high volumes of data, complex data models, performance optimization and large user deployments. Analysis and Content Creation Advanced Analytics. Enables users to easily access advanced analytics capabilities that are self-contained within the platform itself or available through the import and integration of externally developed models. Analytic Dashboards. The ability to create highly interactive dashboards and content, with visual exploration and embedded advanced analytics. Interactive Visual Exploration. Enables the exploration of data via the manipulation of visual properties and visual forms representing aspects of the dataset being analyzed. These tools enable users to analyze the data by interacting directly with a visual representation of it. Augmented Data Discovery: Automatically finds, visualizes and narrates important findings such as correlations, exceptions, clusters, links and predictions in data that are relevant to users without requiring them to build models or write algorithms. Mobile Exploration and Authoring. Enables organizations to develop and deliver content to mobile devices in a publishing and/or interactive mode, and takes advantage of mobile devices' native capabilities, such as touchscreen, camera, location awareness and natural-language query. Sharing of Findings Embedding Analytic Content. Capabilities including a software developer's kit with APIs and support for open standards for creating and modifying analytic content, visualizations and applications, embedding them into a business process, and/or an application or portal. These capabilities can reside outside the application (reusing the analytic infrastructure), but must be easily and seamlessly accessible from inside the application without forcing users to switch between systems. Publish and collaborate Analytic Content. Capabilities that allow users to publish, deploy and operationalize analytic content through various output types and distribution methods, with support for content search, storytelling, scheduling and alerts. Overall: Ease of Use, Visual Appeal and Workflow Integration. 18 Gartner Magic Quadrant Report 2018 A Practical System Architecture in MSBI 19 Image from https://bipointblog.wordpress.com/2014/05/28/implementation-of-a-bi- system-using-microsoft-bi-stack-introduction/ Data Management In traditional BI, a special database system called data warehouse or data mart is often used to store enterprise data The purpose of a data warehouse is to organize lots of stable data for ease of analysis and retrieval. Traditional (operational) relational databases facilitate data management and transaction processing. They have two limitations for data analysis and decision support Performance They are transaction oriented (data insert, update, move, etc.) Not optimized for complex data analysis Usually do not hold historical data Heterogeneity Individual databases usually manage data in very different ways, even in the same organization (not to mention external data sources which may be dramatically different). The data warehouse approach is a centralized and structured approach for analytical data management. For more recent personal BI/analytics, data is also kept locally for easy access and manipulation, without much technical support. 20 Data Gathering and Integration Enterprise level data are coming from multiple different sources, but need to be combined and associated Operational databases Spreadsheets Text, CSV PDF, Paper The need to bring together different data/information Autonomous (may not have the control and management of data) Distributed (from different systems and places) Different (in data model, format, or platform) General processing steps - ETL Extraction: accessing and extracting the data from the source systems, including database, flat files, spreadsheets, etc. Transformation: data cleanse, change the extracted data to a format and structure that conform to the destination data. Loading: load the data to the destination database, and check for data integrity Traditional BI focuses on upfront separate ETL processes that load the data in a centralized storage. In modern BI and analytics, data cleanse and transformation may happen just-in-time with analysis. 21 Data is never clean! You will spend most of your time cleaning and preparing data! Analysis Techniques Descriptive reporting Structured and fixed format reports Based on simple and direct queries Usually involves simple descriptive analysis and transformation of data, such as calculating, sorting, filtering, grouping, and formatting Ad hoc query and reporting OLAP (Online Analytical Processing) A multi-dimensional analysis and reporting application for aggregated data Great for discovering details from large quantities of data Business analytics Business analytics (BA) is the practice of iterative, methodical exploration of an organization's data with emphasis on statistical analysis. Advanced and computation intensive: data mining, deep learning, etc. Data mining techniques are a blend of statistics and mathematics, and artificial intelligence and machine-learning. 22 95% of tasks do not require deep learning. OLAP OLAP is a function/operation that is optimized to answer queries that are multi-dimensional OLAP solutions traditionally heavily rely on backend processing and dedicated IT personnel Multi-dimensional queries A dimension is a particular way (or an attribute) of describing and categorizing data Such queries are usually arithmetic aggregation operations (sum, average, etc.) on records grouped by multiple dimensions (attributes) at different aggregation levels. A pivot table or crosstab is usually used for OLAP result view (aggregated data) Example analysis "What is the total sales amount grouped by product line (dimension 1), location (dimension 2), time (dimension 3) and (other dimensions)?" "Which segment of business provides the most revenue growth?" 23 Descriptive and operational report More open and exploratory analysis Basic Techniques in Business Analytics Regression Reasoning, estimating the relationships among variables Forecasting Trend analysis, based on extrapolation of historical data Correlation Relationship discovery between factors (but not causal relationship) Factor analysis Determine impacting variables and their variability 24 Data Mining Data mining (or, knowledge discovery in database, KDD) Processes and techniques for seeking knowledge (relationship, trends, patterns, etc.) from a large amount of data Non-trivial, non-obvious, and implicit knowledge Extremely large datasets Data mining applications use sophisticated statistical and mathematical techniques to find patterns and relationships among data Classification, clustering, association, estimation, prediction, trending, pattern, etc. Common techniques Neural network, genetic algorithm, machine learning 25 A Levels of Analytical Processing 26 Advanced Analytics and Business Intelligence https://www.youtube.com/watch?v=oNNk9-tmsZY Presentation The last mile of BI is the presentation of data or analysis to human users Data presentation is the method by which people summarize, organize and communicate information using a variety of tools, including tables, diagrams/charts, and other visualization techniques Data visualization is the visual and interactive exploration and graphic representation of data of any size, type (structured and unstructured) or origin. Visualization in BI Data visualization is an important part of understanding for information seeking and decision making. Visualization tools have become increasingly important to business intelligence, in which people need technology support to make sense of and analyze complex data sets and all types of information. As organizations seek to empower nontechnical users to make datadriven decisions, they must consider the prowess of data visualization in delivering digestible insights. Visualizations help data comprehension and enhance problem solving capabilities Provide a high level overview of complex data sets Extract/provoke additional (implicit) perspectives and meanings Ease the cognitive load of information processing Recall or memorize data Enable perceptual inference operations and detection of patterns Visualization can also be part of the analysis process (visual analytics) See more details at https://www.edocr.com/v/yqwmqeba/jgzheng/Business-Data-Visualization https://www.researchgate.net/publication/321804138_Data_Visualization_for_Business_Intelligence 27 Presentation is key be a master of power point. Basic Visual Forms/Styles 28 Form/Style Description Typical Types and Examples Embedded visual It is embedded in, or directly on top of, texts and other forms of data presentation (table, graphic, etc.). Conditional formatting (visual cues) Inline chart (Sparkline) Block visual It is displayed as an independent visual unit and occupies a larger space. It is often a part of a report or dashboard, appearing together with other content. But sometimes it can become a standalone visual with many data points or enough complexity. Chart Illustrational diagram Map (smaller) Data table (usually with embedded visuals) Standalone visual It is a standalone application and is not mixed with other types of content or tool. Most interactions are within the visual. It may consist of a combination of different types of visuals. Dashboard Visual analysis tool (or an analytical dashboard) Map (bigger or full screen) See more details at https://www.edocr.com/v/yqwmqeba/jgzheng/Business-Data-Visualization Reports Reports A report is the presentation of detailed data arranged in defined layouts and formats Based on simple and direct queries: usually involves simple analysis and transformation of data (sorting, calculating, filtering, filtering, grouping, formatting, etc.) Traditional reports contain detailed data in a tabular format and typically display numbers and text only. Its purpose is mainly for printing (with styling) or exporting (raw data). It is geared towards people who need data rather than a direct understanding of data. Modern reports can be interactive and visual but the focus is still on detailed data. Sometimes the distinction is a bit blurred with dashboards in some practical cases. http://www.crazybikes.com/mrc/CRAZYBIKES.R00090s A report style "dashboard" (or more like a visual intensive interactive report): https://www.itdashboard.gov/drupal/summary/006 29 Dashboard A dashboard is a visual display of the most important information needed to achieve one or more objectives; consolidated and arranged on a single screen so the information can be monitored at a glance. Dashboard Confusion, Stephen Few, http://www.perceptualedge.com/articles/ie/dashboard_confusion.pdf A set of visualization or presentation of data views organized in a single screen/page The data is generally KPIs and shows trends, breakdowns, and comparisons against a forecast or historical data A dashboard generally contains a variety of different views of data: charts, diagrams, tables, standalone numbers, interactive controls (such a filters) Dashboard vs. report, visual analysis tool, and scorecard http://www.dashboardinsight.com/articles/digital-dashboards/fundamentals/what-is-a- dashboard.aspx The Values of Dashboard Allow decision makers to see a variety of relevant data that affects their divisions or departments Quickly understand data and respond quickly at one place; save time over running multiple reports More: http://www.bidashboard.org/benefits.html 30 Delivery Delivery is about managing and delivering data and analysis results to users 31 Live example: https://discoverer.gsu.edu https://sasweb1.kennesaw.edu/ SASPortal/public Live example: https://www.itdashboard.gov/ Figure from Database Processing13th Edition, by David Kroenke and David Auer BI Users Producers vs. Consumers (at different levels) 32 Figures originally from http://www.bileader.com/ Dashboards.html Technical vs. Business users Users Have Different Needs 33 http://eckerson.com/articles/part-iv-seven-keys-to-a-united-bi-environment https://vimeo.com/68143902 The Fit between Tools and Users 34 Gartner Report, Select the Right Business Intelligence and Analytics Tool for the Right User Published: 23 May 2016 Analyst(s): Cindi Howson BI/Analytics Application Areas BI/Analytics can be applied in all "businesses" (industries, functional areas, or domains) to drive "business" performance Companies (for profit) and financially related Retail, manufacture, real-estate, financial, sports, media, advertising, entertainment, healthcare, publication, energy, etc. Public (non-profit) Organization, institution, association, community, etc. Government: citizen service, city planning, crime, immigration, etc. Personal: personal health, exercise, learning, eating, power consumption, etc. BI can be applied at different levels Strategic: focused on high level organizational strategies and directions Tactic: focused on goals of a organization unit Operational: focused on streamlining day-to-day operations. https://www.business2community.com/business-intelligence/the- four-sides-of-business-intelligence- 0548311#ycaoYFUR04W76YiY.97 35 Sample BI/Analytics Applications Business management Strategic planning Performance management Process intelligence Competitive intelligence Marketing and sales CRM Customer behavior analysis Targeted marketing and sales strategies Customer profiling Campaign management Inventory management Human resource/capital HR analytics Talent management Project and program management Power and energy management Healthcare management IT management Web analytics App analytics Security management Supply chain and Logistics Supplier and vendor management Shipping and inventory control Insurance Government City planning Traffic management Urban Analytics Power usage Education Learning analytics Student engagement and success Institutional effectiveness Social analytics Sports and games analytics 36 BI Market Major vendors Figure from http://www.forbes.com/sites/louiscolumbus/2014/06/24/roundup-of- analytics-big-data-business-intelligence-forecasts-and-market-estimates-2014/ The global Business intelligence market size is expected to grow from USD 17.09 Billion in 2016 to USD 26.88 Billion by 2021, at a Compound Annual Growth Rate (CAGR) of 9.5%. https://www.marketsandmarkets.com/Market- Reports/social-business-intelligence-bi-market- 1048.html Worldwide Business Analytics Software Market Shares, 2015, IDC July 2016 Major Vendors Mega vendors provide complete solutions that cover full spectrum of BI processes.

Image from https://www.birst.com/why-birst/ BI Trends 40 http://www.b-eye-network.com/blogs/eckerson/archives/2011/03/bi_market_evolu.php The Modern/New BI A modern BI platform supports IT-enabled analytic content development. It is defined by a self-contained architecture that enables nontechnical users to autonomously execute full-spectrum analytic workflows from data access, ingestion and preparation to interactive analysis and the collaborative sharing of insights. By contrast, traditional BI platforms are designed to support modular development of IT-produced analytic content, and specialized tools and skills and significant upfront data modeling, coupled with a predefined metadata layer, are required to access their analytic capabilities. 41 Technology Insight for Modern Business Intelligence and Analytics Platforms Gartner Report, October 2015 Analytic Workflow Component Traditional BI Platform Modern BI Platform Data source Upfront dimensional modeling required (IT-built star schemas) Upfront modeling not required (flat files/flat tables) Data ingestion and preparation IT-produced IT-enabled (business-led) Content authoring Primarily IT staff, but also some power users Business users Analysis Predefined, ad hoc reporting, based on predefined model Free-form exploration Insight delivery Distribution and notifications via scheduled reports or portal Sharing and collaboration, storytelling, open APIs A Changing BI Platform 42 Technology Insight for Modern Business Intelligence and Analytics Platforms Gartner Report, October 2015 Some Notable Trends/Features Personal (self service) BI/Analytics Self service enables nontechnical users to autonomously execute full-spectrum analytic workflows from data access, ingestion and preparation to interactive analysis and the collaborative sharing of insights Embedded analytics Use of reporting and analytic capabilities directly in transactional business applications http://www.gartner.com/it- glossary/embedded-analytics/ Search Driven BI Build a report and charts on the fly, using web search style. Most BI and analytics tools require users use a tool to "build" a query or visualization. When users type in a search phrase, such as "sales for New York 2016," and either an existing report or a visualization appears. A search driven environment uses the power of Google-like search and build report and visualizations on the fly.

Jack Zheng Says:

"Kennesaw State University professor Jack Zheng’s concise, content-rich introduction to BI may be the best free comprehensive intro I’ve seen online. You’re basically getting the first-day lecture from one of his college courses. If you were to break the course’s cost down by classes, you’d probably be getting about $1-200 dollars’ worth of information, just by clicking above.
