Method and means for porting an existing application (An) using a relationaldatabase with SQL interface toward a hardware platform (HW2) with a reduced software configuration which does not include an SQL relational-database. The invention emulates an SQL database enabling hardware resources saving and providing a subset of functions in order to: creating SQL tables and defining fields; storing, modifying and deleting data on created tables, with a type check, retrieving such data by using SQL filters. Functions can be subdivided into levels (M1, M2, M3) in order to: convert an SQL statement, coming from an existing user application (An), into a sequence of elementary interface functions (IF1...IFn), use said interface functions to read/write data files (F1...Fn), process output data to be supplied to the requesting user application (An).
