Processing a database query for sets of data includes assigning a unique identifier from an integer space to each entity within data and creating one or more sets of entities each pertaining to a corresponding entity within the data. A representation is then generated on disk for each set of entities, wherein each representation encompasses and is suited for a range of the unique identifiers of entities within a corresponding set and indicates a presence of an entity within that corresponding set. Finally, a query is processed based on the representation for each set of entities to retrieve data satisfying the query, wherein the representation provides a constant time for association and dissociation operations that are append-only operations with deferred merge and automatic filtering of deleted and duplicate entities at query time.

Managing large scale association sets using optimized bit map representations

Embodiments generally relate to providing litigation management for multiple remote content systems using asynchronous bi-directional replication pipelines. In some embodiments, a method includes retrieving, at one or more inbound replicators of one or more respective bi-directional pipelines, metadata associated with documents stored in one or more content repositories. The method further includes resolving, at a governance control hub, conflicts associated with legal holds on one or more of the documents based on the metadata. The method further includes sending conflict resolution results from one or more outbound applicators of the bi-directional pipelines to the content repositories, where the content repositories enforce legal holds on the documents.

Providing near real-time and effective litigation management for multiple remote content systems using asynchronous bi-directional replication pipelines

A data structure is generated containing enumerators for data types of a domain, text forms of the enumerators and context patterns for the text forms. The data structure also includes information extraction rules that are associated with the enumerators. The data structure is updated with additional context patterns and text forms that are identified within a set of documents to which text analytic annotators are to be tuned. The set of documents are analyzed against the updated data structure and additional extraction rules are generated based on the analysis.

According to one embodiment of the present invention, a system maps one or more virtual relations to a table of a relational database management system. The system generates a structured query language (SQL) statement for the table from a SQL statement for a virtual relation by applying the mapping to one or more elements of the SQL statement for the virtual relation. Embodiments of the present invention further include a method and computer program product for mapping virtual relations to a table in substantially the same manners described above.
