A computer-implemented system and method for creating a user-defined database interface. A Launch Form module constructs a call comprising user definitions of an identifier for the database, a target data object (database table), approach filters (table fields), and results lines (table fields). An Orbit Form module uses the call constructs to access and query the identified database. Approach boxes corresponding to the approach filters may receive target input values which the Orbit Form module matches, in combination, to records in the database. The Orbit Form module may then retrieve values present in the fields corresponding to each user-specified results line. The Launch form module may also adorn the call with parameters that the Orbit Form module uses to govern retrieval of data from the target database, presentation of filter values, and/or formatting of results pages.
