| As the simulation technology rapidly development and the application widely deployed, the status of the datum involved in and produced by simulation program become more and more important.In the past, because the computer performance is limited and the program is the center of the simulation software, a mass of simulation program datum is separate and disorder, this situation reduced the problems of redundancy, incompatibility and insecurity. In order to satisfy needs of the modem simulation, it is obviously need to manage the enormous datum.In the other hand, the information technology innovation has largely changed the simulation features. The datum that carried all the simulation information has diversified and complicates in construction and display than ever before. For instance, datum of past mainly point to numerical values and characters, now plenty media datum is emerging, which bring the advantages about the vivid manifest of abstract information, at the same time also bring the disadvantage about management of these vast datum.In this paper, I studied currently database technology, analyzed missile flight simulation needs, designed and developed certain air to surface missile simulating database system software.Firstly, total system could be divided into four parts including simulation algorithmic library, simulation knowledge library, flight test database, simulation test database, according to characters of resources and functional differences of flight simulation, and then these parts are designed and accomplished respectively. Notwithstanding simulation algorithmic library don't belong to traditional database, many mathematic algorithm are used during flight simulation, and users can change the simulation strategy and switch mathematic algorithm during simulation experiment, Thus algorithm is also a kind of resources, and all of these algorithm form the algorithmic library. Simulation knowledge library basing on the type of missiles provides realistic and visual model information for users in the formats of media data. Save, query and graphic interaction dealing with the result of actual flight test data are the emphasis of flight test database. Simulation test database is about simulation test, and provide the functions of data management for platform of flight simulation.I applied relation database engine and data files to manage simulation datum.This is one approach that giving attention to two aspect of practical needs and technique condition.This production resolved the problem of missile flight simulation resource management, the method can extend to apply to many kinds of aircraft flight simulation database system development, even can be directly used in similar missile flying simulation resource management. |
