Based On The MDA And UML Techniques Library Management System

Traditional software development model has many problems, such as production efficiency difficult to improve software portability and interoperability problems, high maintenance costs. One proposed OMG Model Driven Architecture (Model A Driven Architecture) is against this background that proposed a new approach to software development. It is to address a variety of incompatible platforms and middleware technology in system integration and interoperability deficiencies exist provides a new idea. MDA's core piece is the model, input to the MDA cross-type re-design effort will be used to generate a variety of components many times.Purpose of this study is the use of MDA and UML technology to build the library management system for sustainable reuse of platform models, the model generated by library management system. Foreign library management system starting in 1954, the U.S. Navy weapons center of the unit matches the search term, the development of today become the countries in the preparation of various MARC formats generally follow the norms of bibliographic data. "Chinese MARC format" has been organized by the Ministry of Culture experts for the country's integrated library management system laid the foundation of the industry. With the development of the industry and software technology advances, the library management software, continually re-building, wasting a lot of manpower and resources, and the development of the company's various heterogeneous platforms also need to be integrated library system, the establishment of library management system the sustainability of the platform model can be reused to solve the above problem.The research method is to use MDA's thinking, with UML tools, from a comprehensive analysis of the demand for library management system to start, resulting in a PIM, reusable model for the integration of the library system provide an ideaThe main job is to in-depth analysis of MDA development approach, with the following aspects of library management system software development, comprehensive improvements:●Using the MDA development method, the developer's attention from the concrete implementation details transferred to come out, make development PIM with specific model of the platform. This development as a model of the work, it can be applied to different technology platform, system design reuse. Once by high-level professional and technical personnel to develop each specific application software can be used in the MDA tools, can make the aim to develop directly convert a corresponding PIM code, general program code developers work will become very small, error rate drops greatly, which naturally can greatly improve the production efficiency.●Internal staff library bibliographic data on operations such as processing and classification, there are strict procedures for data security and efficiency are higher, so the internal staff to operate the module with the C/S structure, the reader starts the use case high demand for convenience, you can use the online service module B/S structure, the database server and front-end between the client browser to use a WEB server. This module is designed for the reader module. To different start of the use of different characteristics of the structure, can satisfy the library staff and the reader two aspects of.●purchase new books every year work order prior to the survey, the reader needs to see what books the library currently does not, then these surveys to compile data that meets the system requirements, to take up a lot of manpower, a new addition this system recommended by readers function, creating an online bibliography recommended projects, and the direct correlation between the reservation form to allow readers to recommend at any time while the library does not need the books, recommended books directly into the procurement order database, as the purchase of reference.Use the mda method creates library management system, the mda tools, improved since then, in the library and internet resource shared by the implementation aspect will show its advantages.
