2.3 Usage Scenarios

   This section identifies four application scenarios and six tool scenarios outlining likely usages of CWM. The application scenarios cover key data warehousing activities. These are summarized in sections 2.3.1 through 2.3.4 and illustrated in Table 2-2 on page 2-6. The tool scenarios in section 2.3.5 and Table 2-3 on page 2-7 cover some significant data warehousing tools from the submitters used in present day practice.

   The purpose of these scenarios is purely to illustrate potential usage of CWM.

   In warehouse operations, two common categories of data movement are (a) loading data into a data store, and (b) accessing data for analysis and presentation from the data store. The ETL Scenario addresses the first category. The OLAP Scenario addresses the second category.
