Transaction processing control method and system

The invention discloses a transaction processing control method and system. The method comprises the steps that after the transaction processing control system receives a transaction request, a transaction type corresponding to the transaction request is determined; according to a predetermined mapping relation between transaction types and database types, the database type corresponding to the determined transaction type is analyzed, wherein the database type comprises a master database and a read-only database associated with data in the master database; and if the database type is a master database through analysis, a response is made to the transaction request based on the master database, or if the database type is a read-only database through analysis, a response is made to the transaction request based on the read-only database. Through the transaction processing control method and system, transaction processing efficiency is improved.
