Database synchronization method based on self-made serialization algorithm

The invention discloses a database synchronization method based on a self-made serialization algorithm. The method comprises a management tool, a release service module and a subscription service module, and is characterized by comprising establishing a self-defined data view metadata structure; generating metadata from the source database according to the structure, wherein the publishing servicemodule extracts data according to the definition of metadata, establishes a self-made serialized storage algorithm, carries out serialized storage on the data and publishes the data, and the subscription service module receives the data published by the publishing service module according to the definition of the metadata, carries out reverse processing on the data and finally updates the data totarget data. According to the method, mechanisms such as minimized transmission of database synchronization and self-defined identification of a data constraint relationship are realized, and self-defined logic processing is
