You define data view records by loading source files into the data view. Then you build the data view based on the sources you've loaded. Some source file types, such as IMS PSBs and SQL DDL contain native code. Other sources, such as IMS DDI and VSAM, are created specifically for AppMaster Builder and require you to code a series of DDI statements. For more information on coding DDI statements, see Coding DDI Sources.
AppMaster Builder looks for data source files in the following directories, all subdirectories of your project:
| Source Type | Directory |
|---|---|
| IMS PSB | PSBSRC |
| IMS DBD | DBDSRC |
| IMS DDI | DDISRC |
| VSAM | DDISRC |
| SQL DDL | SQLDDL |
