Large-scale Engineering Of Information Systems Technology,

With the further development of network, information transported by network also becomes more and more important. Now informative degree of every walk of life has made great progress, however in the fields of national defense, especially in aerial field, informative degree is relatively backward. This paper aims at the characteristics in flight test of aerial field to make certain research in the construction and realization of large-scale database, and according to research the subject, I will design and realize an information platform about flight test data along with our research group. In this paper, I will mainly make study in three aspects.1. One aspect is to study overall architecture of large-scale information system and the development platforms. In this sector, firstly to study the N-tier architecture of current, large-scale information system. Then, to put forward the overall architecture of this system according to it's characteristics.2. The second one is about database design technology. Because the large quantity of flight test data and complicated relations among kinds of information, the database design is more difficult than general one. In this sector, firstly to study traditional database design theory, then, according to the system's characteristics, to design the flight test database based on the theory in combination with practice.3. The third one is about the key technologies research in the large-scale information system, especially in the background platform. Because the final performance and security in the large-scale information systempivotally lie on the background design, this sector is one of the important contents studied in this paper. In the key technologies aspect, I studied parallelism, block, interMedia's application , database debugging technology and so on, which are all the most important technologies applied in this system. Base on the above research contents, this paper also givesa part of design models of the system "Flight Test andMeasurement Engineer Database (FT&MEDB)".
