Business analysis in data warehousing

  1. 1. Business Analysis DATA WAREHOUSINGREPORTING AND QUERY TOOLS AND APPLICATION Dr. Himanshu Hora SRMS College of Engg. & Tech., Bareilly, Uttar Pradesh (INDIA)
  2. 2. Reporting and Query ToolsTools Categories :  Reporting  Managed Query  Executive Information System  OLAP  Data Mining
  3. 3. Reporting Tools Production Reporting Tools Companies generate regular operational reports or support high volume batch jobs, such as calculating and printing pay checks. Report Writers (Desktop tools for end users) Crystal Reports / Actuate Reporting System Users design and run reports without having to rely on the IS department.
  4. 4. Managed Query Tools Managed query tools shield end users from the complexities of SQL and database structures by inserting a “metalayer” between users and the database. Metalayer : Software that provides subject-oriented views of a database and supports point-and-click creation of SQL.
  5. 5. Executive Information System Tools First deployed on mainframes. Predate report writer and managed query tools. Build customized, graphical decision support Apps. or “briefing books”. Provides high level view of the business and access to external sources e.g. custom, on-line news feed. EIS Apps highlight exceptions to business activity or rules by using color-coded graphics.
  6. 6. OLAP Tools Provide an intuitive way to view corporate data. Provide navigation through the hierarchies and dimensions with the single click. Aggregate data along common business subjects or dimensions. Users can drill down, across, or up levels.
  7. 7. Data Mining Tools Provide insights into corporate data that are not easily discerned with managed query or OLAP tools. Use a variety of statistical and AI algorithms to analyze the correlation of variables in data. Interesting patterns and relationship to investigate. IBM’s Intelligent Miner, DataMind Corp.’s DataMind
  8. 8. ApplicationsNeed for applicationsSome tools and Apps can format the retrieved data into easy-to-readreports, while others concentrate on the on-screen presentation. Asthe complexity of questions grows, these tools may rapidly becomeinefficient.Application often take the form of custom-developed screens andreports that retrieve frequently used data and format it in apredefined standardized way.
