Application Schema Metadata
Schema metadata about tables includes this information:
- The application module in which a table belongs
- Data about table triggers, such as whether a primary key is generated, whether inserts or updates are allowed, and so on
- Data about AlphaKeys, which are system-generated values used as keys
- Data about user extended table (UET) inheritance
- Data about views generated for multi-site tables
- Data about application-specific table extensions, such as ERDBGW population for APS
The system refers to this metadata when generating table triggers.
Note: When you create a new table, first try generating and testing table
triggers without adding your table to the metadata. If it works the way you
want, do not add it to the metadata. Otherwise, refer to this section and the
related topics to determine how to add metadata to adjust the generation.
