LDBC (Liberty DataBase Connectivity) is a JDBC driver that provides vendor-independent database access. With LDBC, your application will just work on all major databases and you don't have to change any source code. LDBC is based on ANSI-SQL and JDBC.
LDBC radically simplifies porting of existing or new applications to new databases. The main components of LDBC are a JDBC driver and a SQL grammar converter. LDBC completely shields the application from database vendor specific code. Included SQL grammar and JDBC API documentation.
LDBC is not meant to be a persistence layer or object relation mapping.
The main idea of LDBC is providing a standard way to access a SQL database
LDBC comes with a JDBC driver that makes every database behave exactly the same way. Internally, LDBC uses the 'regular' vendor specific JDBC driver, but this is not visible to the application.
Without the LDBC driver (BAD)
With the LDBC driver (GOOD)
The app works only with one database, because:
The application works with all major databases, because:
Grammar: The SQL syntax supported
Databases: The list of supported database vendors and drivers
JDBC API: Lists supported JDBC interfaces
Functionality: What is supported and what is not (yet) supported
How to Build: The software required to build LDBC yourself
