Core Components and Specialized Tools
SQL Developer Data Modeler
The SQL Developer Data Modeler is a specialized tool used for database design and data modeling. It provides a dedicated environment for capturing, modeling, managing, and exploiting metadata (data that provides information about other data). While some documentation indicates it as a for-cost option requiring a separate license, other Oracle sources list it as free, with a read-only viewer version also available.
Extensions and Integration
To enhance its core functionality, Oracle provides an Extensions Exchange, allowing users to add specialized capabilities to their environment. Additionally, the tool integrates with the Oracle Web Agent (OWA) or MOD_PLSQL, which serves as an extension module for Apache web servers to handle web-based output.
