Autonomous transaction implementation method and system based on concurrent mechanism and application

The invention belongs to the technical field of database management systems and computer software, and particularly relates to an autonomous transaction implementation method and system based on a concurrent mechanism and application. According to the method, a transaction framework model in which autonomous transactions and main transactions are parallel is designed, in the model, various transaction operation contexts of the autonomous transactions are completely identical to those of the main transactions, the autonomous transactions and the main transactions are completely consistent in transaction operation modes, and when a system executes the autonomous transactions, an original transaction framework in a database system can be reused, an original transaction interface in the system is called to achieve the autonomous transaction process, and the same result as a traditional implementation method of autonomous transactions is achieved. According to the method, the running program of the database system
