PURPOSE:To shorten the generation time of a definition sentence by automatically generating a schema definition sentence and a table definition sentence from a specification in which the structure of a data base that a user generate is defined. CONSTITUTION:The user generates the specification in which the relation between tables in the data base 7 and the item of the tables are defined by interaction. An automatic generation means for data base structure definition sentence 4 reads e generated specification, and changes the name of the specification to the name of schema so as to generate the schema definition sentence. The attribute of the item of the table defined in the specification is retrieved from a data dictionary storage means 3 and the table definition sentence is automatically generated. Thus, trouble at the time of generating the definition sentence can be saved.
