摘要： A database system includes: a first database having back-end functionality for data storage and database query execution, a database front-end and an interception unit. The database front-end is configured for processing user queries directed to a back-end of a second database, and lacks the capabilities for directly accessing the first database. The interception unit is networked with the first database over a data network, and is configured for monitoring user queries under processing by the front-end to identify queries pertaining to data stored in the first database, and redirecting the identified queries to the first database for execution. Thereby the functionality of the database front-end is provided for data stored in the first database.

摘要： A geographically distributed storage system for managing the distribution of data elements wherein requests for given data elements incur a geographic inertia. The geographically distributed storage system comprises geographically distributed sites, each comprises a site storage unit for locally storing a portion of a globally coherent distributed database that includes the data elements and a local access point for receiving requests relating to ones of the data elements. The and geographically distributed storage system comprises a data management module for forwarding at least one requested data element to the local access point at a first of the geographically distributed sites from which the request is received and storing the at least one requested data element at the first site, thereby to provide local accessibility to the data element for future requests from the first site while maintaining the globally coherency of the distributed database.

摘要： A system for backing up a set of records. The system comprises a database in which to store the set of records and a data management module configured for backing up the set of records in a plurality of record groups in a first continuous data batch using a single data stream in the database and simultaneously logging a plurality of transactions related to one or more of the set of records in the first continuous data batch. Each record group has one or more records of said set of records. The system is designed for recovering said set of records from the first continuous data batch.

摘要： A data access system decouples the data processing from the data storage to provide improved accessibility, integrity, scalability and other features. The system comprises: database units arranged in virtual partitions each independently accessible, a plurality of data processing units, and a switching network for switching the data processing units between the virtual partitions, thereby to assign data processing capacity dynamically to respective virtual partitions.
