Patent number: 5870762Abstract: An improved method for encoding, error detection and restoration of corrupted database files comprises generating a unique record code in each record of a record file, and when a memo file is present, generating a unique memo code in each memo of the memo file for identifying the correlation of the memo to one particular record field and one uniquely identified record. Error detection is achieved by verifying locations of record codes in record files; memo codes in memo files; and the correlation between memo codes in memo file and the record codes in record file. Integrity of record file is restored by searching for record codes and rewriting the located records in correct file structure positions. Memo file integrity is restored by searching for memo codes and rewriting memos in correct file structure positions, and memo pointers are corrected by using the method's correlation between record codes and memo codes to locate correct memos in the memo file.Type: GrantFiled: September 26, 1996Date of Patent: February 9, 1999Inventor: Paul Lee

Patent number: 5857205Abstract: A method for verifying computer generated data in periodically updated and replaced files to determine if data item characteristics in the files have changed in an unexpected manner. The method involves the steps of selecting a first version of each of the data item characteristics and selecting a second subsequent version of each of the data item characteristics. The first version of each of the data item characteristics and the second subsequent version of each of the data item characteristics are analyzed to produce first and second statistical profiles. The first and second statistical profiles of each of the data item characteristics are then compared to each other to determine if any of the data item characteristics have changed in an unexpected manner. Finally, the files being periodically updated and replaced are monitored to determine if the data item characteristics in the files have changed in an unexpected manner.Type: GrantFiled: August 12, 1996Date of Patent: January 5, 1999Inventor: Michael Roth

Patent number: 5832485Abstract: A method and apparatus for selectively allowing data presented in a join view to be modified is disclosed. Data presented in a join view is allowed to be modified if provided to the join view by a key-preserved table. A table is a key-preserved table with respect to a join view if each of the keys of the table is a key of the join view. Key-preserved tables may be identified by inspecting the definition of a join view to identify the base tables of the join view and to generate a graph. In the graph, each node corresponds to one of the base tables. Directed edges between nodes of the graph correspond to relationships, specified in the definition of the join view, between the base tables. The graph is reduced to strong components, each of which corresponds to a set of the base tables in which each base table in the set is routed to each other base table in the set by one or more directed edges.Type: GrantFiled: February 14, 1996Date of Patent: November 3, 1998Assignee: Oracle CorporationInventor: Atif Chaudhry

Patent number: 5826261Abstract: A system, method, and various software products provide improved information retrieval performance from multiple document databases by retrieving from the multiple document databases in response to a user query, a set of documents that globally satisfy the query, even though each database maintains independent document indices, term frequency information, and scoring functions. The global search result approximates, to any desired degree of error, the search results that would have been obtained had the multiple document databases been globally indexed. This is done by sharing at the time the query is executed, a small subset of information about the local relative significance of terms related to the user's query, and from this information, determining a global relative significance of such terms. From the global relative significance, the individual document databases determine their query results, which are then merged into a global set of documents satisfying the query.Type: GrantFiled: May 10, 1996Date of Patent: October 20, 1998Inventor: Graham Spencer

Patent number: 5819277Abstract: A method practiced by a computer system for generating SQL commands to create an integrated global schema. The input is two relational schemas in object-oriented form and a list of correspondences between components, object classes, objects and attributes. Based on correspondences object classes within one schema are folded into one object class, or relation, and likewise, based on correspondences one relation from each input schema is merged into a single relation of the integrated schema. This process is continued until no more object classes can be folded together and no more can be merged. SQL commands are generated based on specified correspondences between attributes depending upon whether a relation of the integrated relational schema was derived from only one relation of one of the input schemas, or is the result of the merger of two relations each from a different input schema. In the latter case, correspondences are based on the attributes of merged relations.Type: GrantFiled: March 26, 1996Date of Patent: October 6, 1998Inventors: Forouzan Golshani, Oris D. Friesen, Thomas H. Howell
