A Brief Report to the Symmetry-Relationship Database Management System and its Application in Geomatics

The symmetrical matrices in geomatics have been generated every day, and their scale have been increasingly and rapidly expanded. The existed data management of symmetrical matrices has been increasingly faced with some great difficulties and challenges. This paper introduces briefly our works on a new expanded relationship database management system, the symmetry-relationship database management system (SRDBMS), that based on a new data model - the symmetry-relationship data model, and then introduce simply our works on the application of the SRDBMS in geomatics.
