Abstract
A middle layer in business applications is provided to wrap all the database management operations generically, to store changed data temporarily, to validate and lock the data before updating the database, and to synchronize the data change and unlock it as a whole when a commit method is called. In embodiments, only six generic methods are needed for all data interactions. Transaction, isolation level, exception format, and performance tuning operations can be performed centrally in the six generic methods. A buffer section may be created in the middle layer. Operations such as insert, update, delete, and select are performed on data stored in the buffer. Buffered data may then be stored in a data storage device.
