Abstract: Storing data in a data store is disclosed, including storing data in a plurality of generalized memory structures and generating an indexing structure that references one or more of the memory structures. Referencing is based on rules expressed in the memory structures. Processing a query in a data store is disclosed, including receiving a query, selecting an appropriate indexing structure to access for the query, and accessing data using the selected indexing structure.

Abstract: A technique is disclosed for maintaining data integrity among a plurality of network applications. The technique includes receiving a request from a first network application, interpreting the request, and executing the request. Executing the request includes accessing data in a distributed backing store. The backing store is a common memory that is accessible to the first network application and a second network application.
