Once the data has been published over to the target server, the applications need to query the published data (content files and their associated properties and attributes) for display on the website.
This is where Documentum JDBC Services, formerly known as eConnector for JDBC, comes into the picture. JDBC is a standard interface to access a database from Java-based applications.
Documentum JDBC Services is a Documentum utility tool that supports most of the standard JDBC APIs and helps applications perform the following functions:
Both Docbase JDBC Drivers and SCS JDBC Drivers are available from Documentum JDBC Services. The Docbase JDBC Driver implements JDBC APIs using Documentum's proprietary DQL (Document Query Language). On the other hand, the SCS JDBC Driver serves as a 'wrapper driver' that supports database connections with standard JDBC drivers for common database servers like Oracle, Sybase, etc.
Figure 4.7 should give you a brief idea about the Documentum JDBC Services architecture.
