Abstract


The sharing test database of aero engine is an item consigned by the emulation center of BUAA. Sharing test database is a combination of the concrete requirement of the aero engine design and test. Through this platform’s establishment, the whole trade’s correlative data can be concentrated, saved and managed effectively. Utilizing the valuable resource reasonably can realize resource sharing and provide technique auspice for the study of aero engine and emulation.According to the data information and data relation of various specialties, the sharing database establishes a data structure that can suffice ten specialties. Based on this, it accomplishes the development of application such as the source data analysis、data extract、data query、and data disposal and data output and so on. The sharing database makes full use of various intricate data types to realize the management of multimedia files, array data and nesting list data. It runs steadily and has a rapid response rate and high efficiency to the user’s request. Further more, the program has a handsome interface and the operation is convenient. It actualizes protecting and managing data in security, guaranteeing the data’s safety and dependability.To this problem, this thesis makes innovative and groping study on the data extract of the sharing test database. The primary contents are as follows:One,it gathering every aspect’s request that every unit of the database put forward, combine data information and data connection, as well as classify of test database and item speciality. Summarizing, analysing and concluding, it decompose function and module of all the darabase system,at the same time describe particularly it that achieving technique guideline of request.Two, it studies the general design concept in detail, including design principle, main function and characteristics. And, introduces the selection of the database, the selection of the development quomodo, and the technology used in the item development, such as the database technique, the Object Oriented technique and the development of dynamic WebPages.Three, it makes a detailed study on the design skill of the database idea model, logic structure, physical distribution; combines the detail requirements of database and adopts the E/R figure to describe the substantiality and relation’s organization form of database system and exhibits the database’s logic structure in the manner of two dimensional data list.Four, it studies the data composing of each specialty in detail. It confirms the data’s extract mode through the analysis of the source data; discusses and studies the implementation method of data management and data extract module and data security mechanism; describes the database’s main development steps, flows, technique and so forth. The results of this thesis can supply references for the development of other similar database.
