Description
Technical field
The present invention relates to the database technology in computerized information field, particularly a kind of device and method of database processing affairs.
Background technology
Along with the development of computer information technology, database technology has wherein become one of the important component part of advanced infotech and core.
In database technology, affairs need be submitted to database processing.So-called affairs just are meant one group of logical operations unit, make data that affairs relate in database from a kind of state variation to another kind of state.Consistance in order to ensure data in the database, the processing of data should be discrete logical operations unit in groups, when affairs are finished by database processing, data consistency in the database can keep, and when a part of operation failure in the logical operations unit in the database processing business process, then whole affairs should all be considered as mistake, and all logical operations unit all fall back on the initial state of data the database from the later operation of starting point.
Database correctly processing transactions can guarantee the integrality and the consistance of data in the database, before affairs are not finished by database processing, guarantees that the data in the database do not increase, deletion is or/and change.
