Problems solved by technology

[0003] When users write data such as chronological books and reports into the database, they need to confirm whether the data is successfully written in time, that is, they need to go to the database to confirm whether the data can be read, but because the data written to the database is synchronized to Reading the database requires a certain amount of synchronization time, making it impossible for users to confirm in time whether the data is written successfully

Abstract

The invention discloses a method for controlling data read-write operation separation. The method comprises the steps of conducting data write-in in a write library according to a received write operation, and storing the time point and data of write operation completing; when a read operation of a user based on the data is received, obtaining the current updating time point of a read library; when the current updating time point of the obtained read library is sooner than the time point of the write-operation completing, executing the data read operation in the write library. The invention further discloses a device for controlling the data read-write operation separation. The aims that the user timely and correctly confirms whether the data in the write library are successfully written in or not, the time is saved, and the data are conveniently and rapidly written in are achieved.

Description

technical field [0001] The invention relates to the field of database data reading and writing, in particular to a method and device for controlling data reading and separation. Background technique [0002] At present, large-scale data systems (for example, ERP enterprise resource planning system), in order to facilitate data reading and writing, the database is divided into a reading library and a writing library, and the writing library is used to record and modify transactional and transactional data. , reading the library is used for querying data such as timebooks and reports. Data writing to the database will synchronize the written data such as time series books and reports to the reading database in a certain way. It takes a certain synchronization time for the data written in the writing database to be synchronized to the reading database. During this synchronization time, the data in the reading database and the The data written to the database is inconsistent. ...
