Generating Documentation of Repository Mappings The Repository Documentation utility documents the mapping from the presentation columns to the corresponding logical and physical columns. The documentation also includes conditional expressions associated with the columns. The documentation can be saved in comma separated CSV, XML, or tab delimited TXT format. You can use the Repository Documentation utility to extract Oracle Business Intelligence metadata to a flat file so that it can be loaded into Excel and RDBMS. You can query the resulting file to answer questions such as If I delete physical column X, what logical columns will be affected? or How many places in the business model refer to the physical table W_SRVREQ_F? Then, you can establish dependency relationships among elements in the repository. Excel only allows data sets of 1,000,000 rows. You might exceed this in a large repository. Therefore, you might want to run the Repository Documentation utility on a subset of the repository by extracting relevant business models into a new project. For more information, see Chapter 3 . The Repository Documentation utility creates a comma-separated values file or a tab-separated values file that shows the connections between the Presentation and Physical layers in the current repository. This file can be imported into a repository as a Physical layer. Note that the file does not include information about repository variables and marketing objects. To run the Repository Documentation utility: 1. In the Administration Tool, select Tools, then select Utilities. 2. Select Repository Documentation and click Execute. 3. In the Save As dialog, choose the directory where you want to save the file. 4. Type a name for the file. 17-14 Metadata Repository Builders Guide for Oracle Business Intelligence Enterprise Edition
