Latest metadata
definition
The latest metadata is used to centrally display the latest metadata information of each source system and database table object in the current platform. It is the main viewing and maintenance entrance after the metadata collection results are accumulated. Users can query table-level metadata based on conditions such as source system, table name, table comments, and library name, and view basic table information, field information, versions, and change records.
Core competencies:
- ✅ Metadata query: Supports filtering the latest metadata based on source system, table name, table comments, library name, etc.;
- 📄 Table-level information management: display table-level attributes such as the associated library name, table name, table comments, description, release status, etc.;
- 🔍 Detailed viewing: Supports viewing metadata details such as basic information, field lists, versions and changes;
- ✏️ Information maintenance: Supports modifying table comments, descriptions, business leaders and other maintenance information;
- 🗑️ Metadata deletion: Supports deletion of invalid or no longer used metadata records.
