| In recent years, with the rapid development of communication industry, communications, engineering design increased, communications engineering design, a very important aspect-Engineering estimates (pre) multi-operator is used to prepare the manual preparation of Excel tables, which prepare the estimates (pre-) be regarded as a relatively tedious work, not only to spend a lot of time, energy, and its data accuracy, standardization, inter-connection between the tables is not easy to ensure. Estimates (pre) calculation of mechanical royalties, the main material so easy to miss, there is no full advantage of computer technology and database technology. How to provide design efficiency, determine the accuracy of project investment and avoid wasted investment, reducing the burden on engineering staff has become the mobile communications industry, the focus of the work and design units.In particular the new estimate in July 2008 the introduction of budgeting, making manual form preparation of budget estimate is more difficult the urgent need for the software forming the budget estimate.In this paper, research and development communication project smart budget organization system, fully taking into account the dynamic changes in standards or the price to meet some provinces and cities or regions within a certain range of data dynamic maintenance needs. Part of the standard system (including standard of scale, materials, equipment, cost standards and algorithms) to implement dynamic maintenance, site-date standardized data to ensure effectiveness.The system based on object-oriented thinking, the use of UML modeling language for system requirements analysis and modeling. Use of stand-alone operation mode, using visual studio 2005 in winform development of technology to achieve system interface development, and the introduction of enhanced interactive features DXperience commercial control; data persistence layer of open-source framework of the castle of activerecord selected modules in order to achieve complete object-oriented development; selection of access document database as a data management platform. System function covers the fixed query management capabilities, multi-level list of list management, flexible and convenient to take into account the cost and computing capabilities, template-based import/export functions. This paper discusses the background of the development of this system, then takes the budget for the communications industry to analyze the status of the software on the system's functional requirements and non-functional requirements in-depth and detailed analysis, including:Overview of the budget document composition, budget system, business processes, and Budget System in project management and systems management needs to flow chart and use case diagram in the form of detailed instructions, based on the needs analysis conducted Budget System architecture. Use. NET technology design patterns is proposed based on budget estimate system design principles, design methods, and the system's overall architecture, functional architecture design, database design and security design. After a detailed description of the system to achieve the main function module, the main implementation modules include:Overview of project management in the new budget, individual projects into single project, copy the single project, remove the single project, summarizes the individual works to achieve, but also in the self-system management definition of fixed base maintenance and materials database maintenance of the implementation, the system version of the update to achieve. Remaining problems and the system are summarized. |
