Embodiments of the invention are generally directed to a system and method for implicit transaction control. A transaction manager receives an indication that an operation is to be executed within a transaction. The transaction manager determines whether a preexisting transaction context is available to provide the transaction for the operation. The operation is enclosed within the preexisting transaction context, if the preexisting transaction context is available.

System and method for implicit transaction control

A database access interceptor includes a statement pool and a table buffer. The statement pool and the table buffer are associated with physical database connections. The interceptor may include a separate instance of the statement pool for each physical database connection. Similarly the interceptor may include a separate instance of the table buffer for each physical database connection.

System and method for a database access statement interceptor

A method and apparatus for providing uniform infrastructure for accessing relational databases are described. A database access statement issued by a software application is received and parsed to determine portability of the database access statement across multiple databases. The database access statement is forwarded for execution if the database access statement is portable.

Embodiments of the invention are generally directed to a system and method for a transaction manager. A transaction manager registers one or more callback methods each having an associated synchronization identifier. An order is defined for the one or more callback methods based, at least in part, on the synchronization identifier associated with each callback method. The callback methods are called in the defined order.

System and method for a transaction manager

A system and method for synchronizing distributed table buffers is disclosed. A node may contain a synch manager and a table buffer having a synch identifier. The synch manager may use the synch identifier to coordinate updates to the table buffer. The updates to the table buffer may be performed in an asynchronous and/or a synchronous manner.
