Method, apparatus and software for differentiating two or more data sets having common data set identifiers

A database management data processing system has been provided. The system can include a host computing system that includes at least one server with memory and at least one processor. The system further includes a database coupled to the host computing system and a database management system (DBMS) executing in the host computing system and managing access to the database through a statement table implemented as a triplestore. Finally, the system includes a triplestore management module coupled to the DBMS. The module includes program code enabled to retrieve from the triplestore a record for a number of rows provided for a common subject in order to validate consistency of data read from the statement table for the particular subject.

Maintaining object and query result consistency in a triplestore database

Provided are methods, data communication apparatus and computer programs for managing communications between a remote communication manager and a set of communications managers in an associated group. The group of communication managers have shared access to resources which enable any communication manager in the group to recover from failures experienced by another communication manager in the group. In particular, recovery of failed inbound and outbound channels is achieved with the advantage of improved availability of data transmissions. Preferably, the recovery uses synchronization information to ensure that data is recovered to a consistent state to that channel recovery is achieved without loss of data integrity.
