The Database Design And Application Of The Socket Launch Emergency System According To GIS

Socket Launch Emergency System, which adopt related emergency measure to guarantee the rocket safety the flight or the ground personnel safety and reduce ground property lose when the occurrence break downs,involve lots of space and attribute data of rocket and related geography information. So we use GIS as the platform to develop,point research the application of GIS in the system, and make the superior handle and excavate. Among them, involve to set up and design space database, user program development and the the contact of space and attribute data. On the design thought of the database system, absorbed the idea of three Schema Structure and two step mapping of database. Clear and definite the way of startting from customer requirement, to the concept designning, and reach the logic designning last. Discussed the method of designning and the similarities and differences with the traditional database. In the system aspect, because space database regard as the middle thing between GIS client and RDBMS, we adopted C/S network mode, manage the space and attribute data together in the database server, and sustain application programm above. For adapt to the effective demand of the rocket launch, besides space and attribute data, this system involve ballistic dat,remote measure data,point of fall data of rocket relic when occurrence accident, and the weather information of the time. So we design the other database coordinate the space and attribute database to manage these data. Oracle manange the attribute database and the other database. MAPGIS manage the space database, and integrate them through integrating management way of MAPGIS. On the development of the application , discussed the advantage and characteristic of the ADO technique for database, and make the introduction according to the application in this system. Discussed inherited Relation of MAPGIS Second Development Class from VC++ and the characteristic when develop space data management programme. To space and attribute data integrated development made the certain research. Through the design and application of Socket Launch Emergency System database, this paper explore the characteristic,way and technique in the process of desing space database, provide to some use for reference and suggestion for space database development according to GIS, make the ground for farther researching space and grade database.
