The invention relates to a method of unified configuration and management to the memory data base by utilizing the system table structure, which comprises the following steps: (1) a configuration fileis created, wherein the description of various data base logical objects is configured and stored in a structure array way; the logical objects at least comprise a business table, and the structure description of the business table at least comprises the attribution description structure and the column description structure of the business table; (2) the creating functions corresponding to different logical objects are determined, which at least comprise the creating function of the business table; (3) the configuration file is read when the data base is started, and the data base logical objects configured in the configuration file are respectively created by utilizing the creating functions corresponding to different logical objects, wherein, at least the business table is created in the memory mapping of the data base by utilizing the creating function of the business table; (4) the specific content of the business table in the configuration file is read in the created memory table, and the inspection of inspection constraint and index constraint is executed in the data base in reading process.
