Oracle BI Publisher 11g: A Practical Guide to Enterprise Reporting
- Share to:
An ETL (or ELT, if you focus on Oracle Data Integrator) tool will perform the BI data integration process. In this way, the Data becomes accessible to the BI solution's end user. The data warehouse is the central point of the BI solution. This contains structured data–detailed and consistent–for query analysis, and provides support for all BI operations from data mining to reporting. Unlike the Online Transaction Processing (OLTP) databases, data warehouses have a very different design to support a large amount of data (which does not need validation in this case), only a small number of users, and at the same time a particular access to the data depending on the particular queries that have to be processed. The historical data coming from business transaction processes is stored using a structure based on business entities, such as customer, product, and time. The result of the business intelligence process is also visible through dashboards, analysis, reports, alerts, scorecards, and all these being available in a variety of designs and formats according to the end user requests.
