Abstract: A novel system and method for interfacing with legacy systems is provided. An enterprise server or host server hosts a front-end interface to a user. The front-end interface is operable to obtain information from the user that is otherwise required to operate the legacy systems. After collecting the information from the user, the enterprise server can then interface with one or more legacy systems, thereby accessing the functionality of the legacy system(s) thereby obviating the need to replace the legacy system with an updated system customized to the enterprise server. A method for recovering a system that interfaces with a legacy system is also provided.

Abstract: A system and method for storing and retrieving data. A graph data structure consisting of a set of nodes connected by a set of links is represented by a set of records. The records correspond to both a set of direct and indirect relationships between pairs of the sets of nodes. Additional information can be captured in the records regarding each of the pair of nodes specified and the relationship between the nodes. In some situations, the records contain information regarding the nodal distance between pairs of nodes. Where the graph data structure is hierarchical, the records can contain information indicating whether the parent node is a parent root node and whether the child node is a child leaf node.
