Abstract: Techniques for organizing a corpus of electronic documents. The electronic documents are organized in a manner that facilitates review of the documents. The documents are organized into a concept-based hierarchical collection of folders based upon contents of the documents.

Abstract: An on-line reorganization method of an object-oriented database with physical references involves a novel fuzzy traversal of the database, or a partition thereof, to identify the approximate parents of all migrating objects. Where the entire database is traversed the process begins from its persistent root. For traversals of a partition the process begins from each object with a reference pointing to it from outside the partition. To facilitate the identification of these inter-partitional objects an External Reference Table (“ERT”) is maintained. During the fuzzy traversal all new inserted and deleted references are tracked in a Temporary Reference Table (“TRT”). After the fuzzy traversal is completed, for each migrating object, a lock is obtained on the identified approximate parents and on all new parents in which references to the object were inserted, as indicated by the TRT.
