Database/Drivers/MySQL Native/Architecture

Wrapped Access

The below picture illustrates the current architecture for the existing MySQL driver, where a generic driver (JDBC/ODBC) is wrapped

MySQL Driver architecture - present

Notes

• Note the additional layer consisting of the JDBC/ODBC->SDBC bridge, which introduces additional complexity, and loss of information (as every abstraction layer)
• The picture is not strictly correct. The applications usually do not work directly on the SDBCX layer, but instead on a layer providing yet more convenience (SDB).

Direct Access

The below picture illustrates the new architecture, where a dedicated C++ driver (Connector/OOo) talks to the MySQL server using the MySQL client library (libmysql)

MySQL Driver architecture - future

'Notes'

• Currently, the MySQL Client Library is linked to / shipped with the MySQL native driver, thus effectively part of OpenOffice.org.
