DATABASE MANAGEMENT DEVICE, DATABASE MANAGEMENT METHOD, AND DATABASE MANAGEMENT PROGRAM

PROBLEM TO BE SOLVED: To solve problems such as necessity for independent construction and management of an individual database system instead of use of an ASP service system database and impossibility of full use of another database system as to important documents, data, and the like in an ASP service system which is used by unspecified multiple customers and can hardly sufficiently ensure security such as limitation of database users allowed to read an important document, because the ASP can not complies with required specification of each customer and offers only the same specification database to the customers. SOLUTION: While directly using an existing system incapable of ensuring security, a system/service with ensured security is offered to only the customer requiring ensured security.
