TDBC Driver Development

This is one of the GSoC 2009 Projects.

Abstract

- Implementing new drivers and adapters to existing interfaces
- Embedding other connectivity projects under TDBC and using it as a slave below others.

PostgreSQL driver. This will be completely new driver, but very similar to existing MySQL one. It will be utilising libpq library and will be coded 99% in pure C.
Oracle driver. As some people expressed they need for such a driver, it was also included in my schedule. This caused some activites to be marked as "secondary", and leaved only in case of resignation from Oracle driver.
Secondary activities - they wre planned to provide a concept of running TDBC over existing database connectivity interface - nsdbi.

18.08	Documentation, finishing unfinished	Done

As of 1.0b13 release of TDBC the PostgreSQL driver is included. Please visit TDBC page for further instructions on downloading and installation.
Oracle driver is still under development. It's currently unfinished, unreliable, but partially usable. The current drawback is lack of documentation and lack of some minor functionality, like types, setting isolation levels etc... If you are interrested in running the driver anyway, the TDBC code including this driver is already avaliable here (it's a Fossil repository). You shouldn't need anything special to compile this driver: just installed Oracle client (at least) and ORACLE_HOME environment variable set appropriately.

RLH I will be very excited to watch the Oracle development happen.
