Description
The questions of constructing optimal logical structure of a distributed database (DDB) are considered. Solving these issues will make it possible to increase the speed of processing requests in DDB in comparison with a traditional database. Optimal logical structure of DDB will ensure the efficiency of the information system on computational resources. The problem of constructing an optimal logical structure of DDB is reduced to the problem of quadratic integer programming. As a result of its solution, the local network of the DDB is decomposed into a number of clusters that have minimal information connectivity with each other.
In particular, such tasks arise for the organization of systems for processing huge amounts of information from the Large Hadron Collider. In these systems various DDBs are used to store information about: the system of triggers of data collection from physical experimental installations (ATLAS, CMS, LHCb, Alice), the geometry and the operating conditions of the detector while collecting experimental data.
