Engineering Database For The Virtual Test Technology Research

Currently, Virtual Test (VT)have got rapid progress in National Defence Industry field. Because of the opening and complex of VT, Database service is supposed to an important component of VT. Therefore, studying Database technology in VT has important significance. The Database can manage all data in VT, set up the beginning conditions, control and dispatch the process of VT and provide sufficient data for replaying analysis and testing.Based on the basic research project of Commission of Science Technology and Industry for National Defense, this paper study Database technology in VT, and the main works are as fellows:First, study characteristics of project database and the Real-time working of VT, introduce RTX technology, reflect shared memory network, broadcast shared memory network. Then Complete the framework architecture of Real-time Memory Database based on RTX.Second, discuss the Database technology and the Real-time technology of VT, then give out this paper's study direction—Real-time Memory database technology in VT, give out the framework, function model and component designing.Third, study and achieve the kernel middle software of Real-time Memory Database. Complete the initiating before an VT, data access, query improvement and data refresh after an VT.Fourth, apply Real-time Memory Database in certain testing system and certain simulation system, and the effect is useful. The real applying have validated that Real-time Memory Database can correctly provide data service in VT based on VMIC reflect shared memory network and RTX technology.
