impossible to design a system completely according to the standardization. Unless the system is very small, it is necessary to add redundancy in a planned manner after the standardization design. Redundancy can be a redundant database, a redundant table, or a redundant field. redundancy at different granularities can play different roles. Redundancy can be increased for programming convenience or for performance improvement. From a performance perspective, redundant databases can distribute
