Abstract: An electronic security scheme and security system for a communications network facilitates the preventing of unauthorized access to an internal resource of an entity's internal computer system. A server includes a first set of ports for communication between an external communications network and the server. The server has a second set of ports for communications between an internal communications network and the server. A first firewall is interposed between the server and the external communications network. The first firewall is coupled to the first set of ports to provide at least one interconnection between the first set of ports and the external communications network. A second firewall is interposed between the server and the internal communications network. In one embodiment, the second firewall is coupled to the second set of ports to provide in a nonnegative integer number of interconnections between the second of set ports and the internal communications network.

Abstract: A communication system and method for supporting the communication of inter-dependent data messages includes determining if a later data message represents an inter-dependent message affiliated with an earlier data message. The communication system and method determines whether a condition associated with the earlier inter-dependent data message is fulfilled. If the condition is fulfilled, communication system executes a command associated with the fulfilled condition and the later inter-dependent data message.

Abstract: A method and system for preparing hierarchical textual file for storage in a relational database allows the user to use readily available commands for querying and manipulating stored in a relational database. A generally tabular data structure contains data attribute fields associated with corresponding data element fields. Hierarchical textual file is accepted containing structured data elements. The data attributes are determined. The data attributes are associated with corresponding structured data elements of the accepted hierarchical textual file. The determined data attributes are stored in the generally tabular data structure of the relational database.
