Abstract: The present invention discloses a method for creating relational database table (s) for a form, which relates to the technical field of software development. A form is mapped to two database tables: a Table Main and a Table Detail, wherein the Table Main is used for storing the attributives of the table header and footer; the Table Detail is used for storing the attributives of the table body; the records of the two tables are associated by header numbers, which are primary keys, not combinations of primary keys from external entities, but independently generated serial numbers with business meaning. The application of the present invention solves the problems of redundant storage and slow access.
