Alternative Ideas for Database Independence

Object-Relational Mapper

An ORM could be used to provide a unified object interface to different RDBMS:

• ​Modeling, which is another, more advanced OR-Mapper.
• ​ADODB, the fast database abstraction layer with a version available for Python.
• ​SQLAlchemy, which is also quite advanced, is discussed further on the SqlAlchemy page. The following plugins exist that implement querying the Trac database using SQLAlchemy: ​SqlAlchemyQueryMacro and ​TracSqlAlchemyBridgeIntegration.
• Some people have been talking about using ​SQLObject to accomplish this goal of database independence.

Store Tickets and Wiki pages directly in the Subversion repository

A compelling idea with many advantages. A page advocating this plan is TighterSubversionIntegration. There has also been a discussion on the Trac mailing list, of which the arguments are summarized on the page WhySQLite.
