To prepare for building a table in the relational database, you need to build a COBOL description for a VSAM file that matches the data used in your application. To accomplish this, you need to locate the following information:
- COBOL file descriptor (FD) for the internal layout of the data within the file
- Description of the unique primary key used for accessing the data file
- Descriptions of any alternate indexes that may be required for the file
