STATIC AND RUNTIME ANALYSIS OF COMPUTER PROGRAM SYSTEMS

A method for analyzing a computer program ecosystem includes performing a static analysis, including identifying static dependencies among elements of the ecosystem based on values of parameters in one or more parameter sets associated with the ecosystem, the elements of the ecosystem including the computer programs of the ecosystem and data resources associated with the computer programs. The method includes performing a runtime analysis, including identifying elements of the ecosystem that were utilized during execution of the ecosystem to process data records. The method includes performing a schedule analysis, including identifying a computer program of the ecosystem that has a schedule dependency from another computer program of the ecosystem. The method includes identifying a subset of the elements of the ecosystem as an ecosystem unit based on the results of the static, runtime, and schedule analyses. The method includes migrating the ecosystem unit, testing the ecosystem unit, or both.
