The present invention relates to method and system for accessing server resources from heterogeneous platforms which are distributed in a distributed application network. One aspect of the present invention is to generate a connecting mechanism, i.e. a connector between the relational data base and the non-relational data system which must be programmed as well, but which is-once programmed-independent of changes made to the application used on the client side during program maintenance. According to an advantageous aspect of the present invention this is achieved by programming so-called 'stored procedures' which access the non-relational data and which process them according to prior art relational data base technology in order to be accessed by JDBC, ODBC or CLI interface for e.g. from IBM DB2 relational database technology on the client side.
