PURPOSE:To reduce the load of a user and to improve the productivity for development of software by deciding a data base access language that is produced based on a file name. CONSTITUTION:A data base access language to be generated based on a file name contained in a work program is decided and at the same time a program is generated based on the access language via a compiling control part 1e, a file attribute control table 1f, and the compiler groups 1g and 1h. Thus the developer of the work program is not required to be conscious of a specific data base system that stores the file to be used and then to be conscious of a specific data base language to be used to have an access to the data base system. As a result, the load of the program developer is reduced and the productivity is improved for development of software.
