Design And Application Of Test Data Management System

The complexity of the system and supporting techniques in the aerospace industrybring more and more huge risk in aircraft and weapon test. The construction of testdata information management system realizes the test data accumulation. It makes theconstruction of intelligence aerospace test system, becomes the development trend ofaerospace information. In this thesis, on using information resources management,data collection and data resources sharing technology, in the Asp.net and Oracledatabase development environment, it is analyzed, designed and implemented adedicated system for aerospace, named TDM (Test Data Management) system, whichincludes front data collection and application service system, business logic systemthat helps user to effectively storing, classifying, indexing and calculating the data,data repository that solves effectively the aerospace test data management problem,such as diversification, low utilization ratio and lack of integrity, and supportsenterprise to manage the test data and trial related business process in the scientificresearch and production.Main work of this thesis is covered the scope of analysis, design, implement andapplication for TDM System. At first, it is based on the user personalization, through acomparison of existing technology, and used Oracle as database, Asp.Net as platform,and Java Script technology for the design of TDM system. Secondly, by analyzing theactual needs of aerospace companies, and specificities of aerospace test data, it isdetermined its functions and modules, and presented a formal expression for businessprocess. Thirdly, according to the abstract level between data elements, and relationaldatabase mapping rules, it is designed and implemented the databases; it is also basedon experimental data security, established security model and data access control, toachieve effectiveness and safety of aerospace test data management. Finally, it ispresented a standard management for system process by test project, datamanagement, source management and files management.TDM system designed based on business user habits, navigates the test data in themanagement system. Users can locate easily target data; shift a variety of data formatsto user-defined format, and save to the database for unified management. System usesdata reusing framework to realize the quick application of historical test data to thecurrent analysis process. In addition, the system supports import and manually enteruser-defined format, and control data access.
