A database-based heterogeneous data batch synchronization method is characterized in that in case of limited system computing resources, self-technologies and interfaces of database management software are fully utilized, heterogeneous data synchronization units are realized in a metadata manner, and batch parallel synchronization is performed by virtue of a first-come-first-service (FCFS) scheduling algorithm. The method has the beneficial effects that the self-technologies of the database management software are fully utilized in case of the limited information system computing resources, and the batch parallel synchronization of heterogeneous data is realized by use of the FCFS scheduling algorithm of an operation system. According to the method, by use of self Database link mechanism of a database, a JOB management mechanism is updated, so that a synchronization process of metadata-level heterogeneous data is managed in a dynamic and batch manner to perform data synchronization, and the consistency and integrity of data in a whole heterogeneous data type system can be ensured.
