This chapter describes the Data Warehouse Center metadata that describes source databases and target databases. Other applications can export the metadata to share information about the databases.
Table 54 describes the mapping between each object in the tag
language file and the corresponding logical object in the Data Warehouse
Center.
Table 54. Logical objects for source and target databases
| Object in tag language file | Data Warehouse Center logical object | See: |
|---|---|---|
| DATABASE | A warehouse source or warehouse target | DATABASE object |
| TABLE | A table, file, or IMS segment | TABLES object |
| COLUMN | A column or field | COLUMN object |
The Data Warehouse Center also defines relationships between the database, tables, and columns. The section for each object lists the relationships in which the object participates that are useful for partner applications.
