Description
Chapter 6 - Database Management and Business Intelligence What are Data, Information, and Knowledge? - Collect data about various subjects to transform it into information and knowledge. - Information and knowledge have tangible value. - Knowledge becomes an important asset. - The flow of data and information to create knowledge is what creates value in organi- zations. The Data-Information-Knowledge Continuum - Data are raw unorganized facts, numbers, pictures, and so on. - Information is data that have been organized and are useful to a person. - Knowledge is created when a person combines experience and judgement with infor- mation. - Applying knowledge is how business people create and add value to organiza- tions. - Wisdom adds insight and ethics to the experience and professional judgement inherent in knowledge. - Wisdom enables business leaders to perceive the underlying meaning and nu- ances of a business situation and ensures that knowledge from all relevant sources is considered in the final decision. - Humans ---> wisdom and knowledge - Computers ---> information and data - The cost and complexity of the tasks to be accomplished increase as you move up the pyramid. - Information technology and systems assist primarily with collecting, collating, and ana- lyzing data and information. Lifelong Knowledge Creation - Explicit knowledge is knowledge that is readily codified. - Tacit knowledge is knowledge that you gain through experience, insight, and discovery. - Data ---> Information ---> Knowledge Knowledge Work Activities - Knowledge work involves the discovery, analysis, transformation, synthesis, and com- munication of data, information, and knowledge. - Work flows are the steps you go through. - Work product is the outcome of your building efforts. Chapter 6 - Database Management and Business Intelligence Discovery: Finding Data, Information, or Knowledge - Discovery is the finding of data, information, and knowledge relevant to a task, prob- lem, issue, or opportunity (the context). - Being with an idea to look for, then reflect on where information related to the task may exist, then retrieve relevant data from those various sources and assess its value to the decision at hand. - Strong internet research skills and awareness of limitations of this source of data can help create business value for your organization. Analysis: Investigating and Examining the Available Data, Information, and Knowledge - Analysis is breaking down the whole into its more discrete parts to better understand how it works. - Process mapping if you are analyzing a business process. - Quality assurance if you are analyzing product quality. - Performance testing if you are assessing fitness or standards. - Information ---> Knowledge ---> Wisdom Transformation: Organizing Discovery Results - Transformation is knowledge work that requires you to use the results of your analysis to deepen your understanding of the data and information. - IT can help you transform data regardless of who did the discovery and analysis work. - Larger organizations with many transactions, often use database software for storing and transforming data. - Transformation ---> Synthesis Synthesis: The Sum of the Parts - Synthesis allows you to interpret trends or patterns that seem to explain the past and the present, and may suggest courses of action likely to favorable influence the future. - When correlated and synthesized into a discernible pattern, there may be a potential terrorist threat to deal with. - While systems can provide the summary information, only people have the ability to put this information into the proper context and draw conclusions from it. - Synthesis ---> Communication Communication: Sharing Analysis with Others Chapter 6 - Database Management and Business Intelligence - To help your employer create business value, you must have strong communication skills. - Communication is the ability to share you analysis, ideas, and solutions with others. - Communication technology includes messages such as email and instant messaging. Databases: The Primary Data Storage for Organizations - All business information systems rely on the use and storage of data. - The primary technology used to store, manage, and allow efficient access to data is the database. - A database consists of interrelated data that are stored in files and organized so that computer programs can quickly and easily access specific pieces of data. - A database management system (DBMS) is a collection of software that allows users to create and work with a database. - A database and a DBMS make up a database system. - The people who create and manage the database, sometimes known as database ad- ministrators (DBA), use the tools in the DBMS to do their work. The Data Hierarchy - To organize data in a database, most users rely on the data hierarchy. - The data hierarchy organizes stored data in increasing levels of complexity. - Database ---> File (Table)
