According to some embodiments, a method includes running a first application program on a computer system, running a second application program on the computer system, and running a data availability manager (DAM) program on the computer system. The first application program is operative to indicate to the DAM program that a first data item processed by the first application program is available for further processing. The DAM program is operative to determine a second data item that is dependent for processing upon availability of the first data item and to indicate to the second application program that the second data item is ready for processing.
