Abstract: A database management method and system. The method includes dividing, by a database system, a data partition into a physical partition layer and a logical partition layer, wherein the logical partition segment and the physical partition segment are mapped to each other using a mapping relationship; receiving, by the database system, a data operation instruction of a user, and determining a logical partition segment to which a data record that is requested for operation by the data operation instruction belongs; determining, according to the data operation instruction and the mapping relationship, a physical partition segment that is corresponding to the determined logical partition segment and at the physical partition layer to perform an operation on the data record that is requested for operation by the data operation instruction.
