ABSTRACT:
A computerized system and method for electronically storing, retrieving, separating, comparing and interrelating data which is maintained in a predetermined classification scheme. Data is electronically stored under the predetermined classification scheme in the form of hierarchal information trees. Data corresponding to a selected attribute may be found in an information tree by using a CRT terminal to scan the various levels of the hierarchy of the tree. As the various levels of the tree are scanned, nodes in each level of the tree are selected in accordance with the desired attribute which is being searched. The selection of various nodes in the levels of the information tree defines one or more concurrent paths through the tree which provide access to all data classified under the information tree corresponding to the attribute being searched. A CPU generates an encoded representation for each set of concurrent paths that are searched through the information tree. Each set of encoded paths is identified by a keyword that corresponds to one of the searched attributes and each keyword with its associated set of encoded paths is stored. The stored keywords and their associated encoded paths may be selectively retrieved and combined in a logical arithmetic unit to produce a particular set of encoded paths which provides concurrent multiple path access through the hierarchal information tree to all data corresponding to a desired combination of attributes. Alternatively, each retrieved set of paths may be used to identify an attribute that is stored in a hierarchal decision table tree, thereby providing access through the decision table tree to all data corresponding to the desired combination of attributes. A special purpose module is also provided which operates to compact the format of the encoded path representations prior to their storage and which also operates to re-expand the format of the encoded path representations after their retrieval and prior to manipulation in the logical arithmetic unit.
