【摘要】：隨著互聯(lián)網(wǎng)行業(yè)的井噴發(fā)展和移動設施的不斷創(chuàng)新發(fā)展,手機正在影響和改變著我們生活的方方面面。而手機智能性也日益成為人們購買手機的參考條件,現(xiàn)如今手機操作市場又是Android、IOS、WP三分天下,其中,由于安卓系統(tǒng)的開放性,這使得安卓操作系統(tǒng)在手機市場上占據(jù)半壁江山�！叭r(nóng)問題”一直是我國農(nóng)業(yè)的重要問題,許多農(nóng)產(chǎn)品面臨著滯銷問題。中國要想成為世界貿(mào)易的核心,不僅要有勞動力和原材料資源,還要靠技術的推動。市場上有需求也有供應,這就是大宗商品交易中心為什么產(chǎn)生和發(fā)展的現(xiàn)實基礎。利用安卓系統(tǒng)的高份額市場占有率,實現(xiàn)農(nóng)產(chǎn)品交易系統(tǒng),讓農(nóng)產(chǎn)品的提供者和消費者都能及時的進行商品交易,利用技術解決農(nóng)產(chǎn)品的現(xiàn)實問題,促進大宗原料商品的流通。本論文根據(jù)用戶和行業(yè)實際需求出發(fā),設計并實現(xiàn)了基于Android復用技術的農(nóng)產(chǎn)品系統(tǒng),結合軟件復用技術,將軟件復用技術應用到了系統(tǒng)的開發(fā)過程中。軟件復用技術是利用已經(jīng)存在的有關知識、技術、理論來解決新的軟件需求,從而達到減小開發(fā)的成本和費用的目的。軟件復用無疑是一種提高軟件生產(chǎn)能力和保證軟件質(zhì)量的重要技術手段。通過應用軟件復用技術于該交易系統(tǒng)中,達到了對現(xiàn)實問題的解決以及節(jié)約軟件開發(fā)和維護的成本的目的。本論文的主要工作內(nèi)容有以下幾點:(1)結合軟件復用技術設計并實現(xiàn)該系統(tǒng)。軟件復用技術是解決“軟件危機”非常重要的手段,目前的軟件復用級別也不僅僅是代碼層的復用,甚至包括前期的設計文檔都可以進行復用。通過軟件復用技術與系統(tǒng)的設計、實現(xiàn)過程相結合,開發(fā)出一個既有現(xiàn)實意義,也符合軟件開發(fā)行業(yè)標準的應用程序。(2)研究Android系統(tǒng)實現(xiàn)過程中應用到的軟件復用方法。從實際開發(fā),了解安卓開發(fā)的具體過程,聯(lián)系軟件復用的理論知識,提取客戶端可以復用的構件。結果分析表明:論文研究的基于Android復用技術的農(nóng)產(chǎn)品系統(tǒng)的設計與實現(xiàn)中,用可行的辦法來達到復用的目的,減少后期二次開發(fā)和維護的成本,通過工程化的開發(fā)方法,杜絕粗糙的開發(fā)生產(chǎn)方式,從而解決“軟件危機”帶來的各種問題,如生產(chǎn)效率低下,開發(fā)、維護成本高,軟件質(zhì)量難以保證等。
[Abstract]:With the blowout development of Internet industry and the continuous innovation and development of mobile facilities, mobile phones are affecting and changing all aspects of our lives. Mobile phone intelligence has increasingly become a reference for people to buy mobile phones, and now the mobile phone operation market is three parts of the world, among which, because of the openness of Android, Android operating system accounts for half of the mobile phone market. The problem of agriculture, rural areas and farmers has always been an important problem in China's agriculture, and many agricultural products are facing unsalable problems. If China wants to become the core of world trade, it must not only have labor and raw material resources, but also rely on the promotion of technology. There is demand and supply in the market, which is the realistic basis for the emergence and development of commodity trading centres. Taking advantage of Android's high market share, the agricultural products trading system can be realized, so that the suppliers and consumers of agricultural products can trade goods in time, and the technology can be used to solve the practical problems of agricultural products and promote the circulation of raw materials. According to the actual needs of users and industries, this paper designs and implements the agricultural products system based on Android reuse technology. Combined with the software reuse technology, the software reuse technology is applied to the development process of the system. Software reuse technology is to use the existing knowledge, technology and theory to solve the new software requirements, so as to reduce the cost and cost of development. Software reuse is undoubtedly an important technical means to improve software production capacity and ensure software quality. Through the application of software reuse technology in the trading system, the purpose of solving practical problems and saving the cost of software development and maintenance is achieved. The main contents of this paper are as follows: (1) combined with software reuse technology, the system is designed and implemented. Software reuse technology is a very important means to solve the "software crisis". The current level of software reuse is not only the reuse of the code layer, but also the previous design documents can be reused. Through the combination of software reuse technology and system design and implementation process, an application program which not only has practical significance, but also conforms to the standards of software development industry is developed. (2) the software reuse method applied in the implementation of Android system is studied. From the actual development, understand the specific process of Android development, contact the theoretical knowledge of software reuse, extract the components that can be reused by the client. The results show that in the design and implementation of agricultural products system based on Android reuse technology, feasible methods are used to achieve the purpose of reuse, reduce the cost of secondary development and maintenance in the later stage, and put an end to rough development mode of production through engineering development method, so as to solve various problems caused by "software crisis", such as low production efficiency, high development, high maintenance cost, difficult to guarantee software quality and so on.
