ABSTRACT:
A data base system according to the present invention has a data base including at least one table and executing predetermined data processing by accessing to the data base in accordance with transactions. The data base system comprises a plurality of management process for executing data processing in accordance with assigned transactions, a plurality of buffers respectively provided for the plurality of management process, for holding partial copies of the table as blocks, data management table for storing a number of blocks held by each of the plurality of buffers, and transaction control section for assigning the transaction to the management process corresponding to the buffer which holds the largest number of blocks on the basis of the number of blocks stored in the data management table.
