摘要：PROBLEM TO BE SOLVED: To provide a database management system capable of reducing a data retrieval time at data retrieval and reuse of retrieval result. SOLUTION: This database management system 1 is provided with a first storage part 10 for storing a customer table 101 wherein an information concerning a customer is added with ID for identifying the customer, a retrieval part 14 for conducting retrieval of the customer table based on retrieval conditions when a retrieval request under a predetermined condition is received from outside, and an assembly table 111 for storing the ID of the customer obtained by the retrieval by the retrieval part as one assembly. At reuse of the retrieval result, the ID is read from the assembly table, thereby obtains the same result as re-retrieved. The assembly table stores the ID, therefore, a storage region can be steeply reduced compared to a conventional technique wherein the retrieval conditions or retrieval processes are stored to re-execute the retrieval.
