  • Method of integrating software application programs using an attributive data model database
    Patent number: 4864497
    Abstract: A common data structure for access by several application programs is created from a single primitive data element or attribute data object. The attribute data objects can be extracted from node data and node data descriptors in the application program's databases. The attribute data objects are arranged in an attribute file in accordance with certain rules which impose a hierarchical organization upon the attribute data objects. Nonhierarchical relationships may also be used to represent the node data descriptors. The simplicity of the attribute data objects and their lack of limitations make them well suited for use with a wide variety of application programs' databases.
