Abstract
A dependency analyzer for a data processing system comprising at least one computer hardware processor configured to generate dependency information among variables, which may appear in any of multiple programs written in different source languages. The data processing system may parse each program, regardless of the language in which the module was written. Parsed information about each program may be recorded in a first-type data structure and then may be converted to a format representing dependencies among variables. Dependency information for each of the plurality of programs may be expressed as a combination of language independent constructs, which may be processed together, to generate dependency information for the data processing system. The dependency information may be recorded in a dependency data structure and further used for operations, such as data quality checking and change control for the data processing program.
