The Framework for Java Database Connectivity (JDBC) was implemented to demonstrate the ease with which a JavaTM application may be designed to access a source code repository using a relational query language, such as SQL. The design was made general enough to accommodate easy access to virtually any data source. The framework supports parsing of the SQL query along with calculations supported within the SQL 92 standard specifications. Access to the data source is performed through the creation of a specific plug-in.
