Graph-based models using external files

Abstract

An overlay system is provided that includes a storage element and processing circuitry coupled thereto. The storage element stores an executable graph-based model that includes a plurality of node groups, a file export overlay node, and a file mapping overlay node. The processing circuitry creates, using the file export overlay node and the file mapping overlay node, a master file that implements the executable graph-based model in a server associated with the overlay system. The processing circuitry creates, in the master file, a plurality of schemas that implements the plurality of node groups. In a first schema, the processing circuitry creates a first set of fields that implements a first set of active nodes of the first node group. Further, for the first field, the processing circuitry creates a first set of records that implements a second set of active nodes associated with the first active node.
