1. A computer-implemented method for generating a query in a first fourth generation language at a native system to a non-native database system capable of processing queries in a second fourth generation language, comprising the steps of:

  • analyzing a query initiated by a client application in a first fourth generation language at a native system to a non-native system database capable of processing queries in a second fourth generation language, to identify specific non-standard syntax representative of a function in the query that cannot be evaluated by the non-native database system;

    if said specific syntax is discovered, transforming the query through the use of formats into an equivalent query expression that can be processed by the non-native database system; and

    transmitting the equivalent query expression to the non-native database system for having the non-native database system return results responsive to the query, to the client application.
