The Oracle source extracts metadata from Oracle databases, including:

• Tables and Views: Standard relational tables and views with column information, constraints, and comments
• Stored Procedures: Functions, procedures, and packages with source code, arguments, and dependency tracking
• Materialized Views: Materialized views with proper lineage and refresh information
• Lineage: Automatic lineage generation from stored procedure definitions and materialized view queries via SQL parsing
• Usage Statistics: Query execution statistics and table access patterns (when audit data is available)
• Operations: Data modification events (CREATE, INSERT, UPDATE, DELETE) from audit trail data

The connector uses the python-oracledb driver and supports both thin mode (default, no Oracle client required) and thick mode (requires Oracle client installation).

As a SQL-based service, the Oracle integration is also supported by our SQL profiler for table and column statistics.
