Abstract


Increasingly demanding requirements of modern science and technology and the development of the aviation industry on the development of the design of the aero-engine. Basic research and applied weak, lack of technical reserves situation must be addressed in the design of aero engine development. With the development of computer technology as a project platform, database technology, computer-aided design (CAD), computer-aided manufacturing (CAM) and computer-aided test (CAT) is gradually introduced into the aero-engine design, and eventually built to adapt to the development of the modern aero-engine design need aero engine design system. Engineering database system is a national foundation for scientific research, the design goal is to combine the aero-engine industry, information technology planning, with the distributed database and computer network communication technology, by completing the establishment of the different parts of the aero-engine database, database technology in the aviation engine design application, complete database technology the advance technological breakthrough in the field of aero-engine applications, and provide technical support for the whole development of aero-engine design, the effective management and use of the experimental data obtained in the major projects. This thesis is on this basis for the development and testing process, data consistency and integrity to study and propose concrete solutions to be implemented. For users of the database design needs, combined with the practical problems faced by our hospital and the system in the field of aircraft engine development, building engineering database system in the form of distributed database structure. For the shared use of the database industry characteristics that may arise in the process of database operations data consistency and integrity to make a specific analysis, the choice of the Oracle database system as the basic platform for the engineering database system, on this platform The blockade mechanism using Oracle database system providing Preliminary concurrency control of database operations. Threads in JAVA language, language-level support for concurrency control, fast and accurate system involves data management, and engineering analysis applications require a large amount of data, using the program function of the two parts concurrency control, thus ensuring that the user can more quickly and accurately in the use of the process of extracting data information. Concurrency control technology used in the design and testing of database system development, so that the resulting information can be accurately and quickly extract, to avoid inaccurate or incomplete data that may arise in the process of engineering analysis information to improve the information inquiry use efficiency.
