Abstract

The invention discloses a database data reading-writing device and method. The device is arranged on a data server. The database data reading-writing device comprises a reading unit for reading original data from an application server, packaging the original data to obtain target data and caching the target data to a caching queue and a submitting unit for reading conditions according to preset caching and storing the target data cached in the caching queue in a database. By the adoption of the scheme, reading-writing tasks in the database data synchronizing process are separated, the reading unit reads the data from a peripheral database, performs package and then writes the data in a high-speed caching queue, the caching queue has high reading-writing rate, accordingly the task reading efficiency is improved, the submitting unit extracts the data from the queue and performs batch saving according to given fixed step length. Accordingly, the reading unit and the submitting unit respectively and independently operate, and the concurrence efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method and device for reading and writing database data. Background technique [0002] With the establishment of a new project, when building a new project, a large amount of data is required to initialize the database. These data often come from multiple peripheral system databases. A data table in this system often needs to synchronize data from multiple peripheral databases. It takes a lot of time at the beginning of the project Develop timing tasks to synchronize data from different data tables in different databases to this system. [0003] Usually choose a popular (ORM) database mapping framework, such as Hibernate, without writing SQL statements, read from the peripheral database, traverse the data list, and insert into the database one by one. This mode is more efficient in development and code writing is faster. [0004] However, in actual production, when hundreds...
