【摘要】：企业战略策略之一就是成本预算管理，成本预算管理的主要目的是控制利润，达到预定目标，对项目实施之前进行全面详细的预算，并对实施过程进行预算追踪和实施结果进行分析，评估预算，从而构建起对成本、利润的全面的控制和管理体系，将公司管理的事后核算转变为事前预算，事中控制，，以使企业的经营风险除低，使企业的经营活动在预算管理的管控下有序的进行。成本预算管理作为企业战略实施的一个重要的控制工具，目标利润为导向的企业项目，实施全面预算管理，提供全面的预算编制，预算追踪及预算分析，以有效地建立一个管理控制系统为了实现软件设计的高内聚低耦合的目的，本系统在设计思想方面充分利用传统三层架构的设计思想并在其基础上不断创新，同时在开发模式方面充分利用了B/S的开发模式的优点。针对该系统，我们在服务层采用WCF RIA服务来代替传统的Web service，其主要优点在于WCF服务不但在数据传输的时候对传输的数据进行加密，同时客户端调用WCF服务的时候可以采用异步操作，这样就提高了服务器对数据的处理效率。在数据的访问层，我们采用的是Linq To Entity技术将要操作的数据进行实体的封装，用来优化传统三层架构中ADO.NET访问技术，其优点是一方面避免了SQL语句的注入式攻击，同时它将要处理的数据封装成实体，减轻了因前台频繁访问数据库而对服务器带来的数据处理等方面的压力，提高了服务器处理数据的效率。前台使用Silverlight技术，实现了跨平台跨浏览器，支持微软及苹果的多种操作系统和IE、Firefox等多种流行的浏览软件。该系统能够满足项目预算管理方面的各个需求，同时能够根据企业个性化的预算管理需求提供专业的解决方案。该系统实现的主要功能包括人员管理、权限管理、基价管理和项目管理以及数据安全性等模块。人员管理用来实现系统内人力资源的配置管理；能够根据公司内部的需要对公司已存在部门进行修改、删除和查询，同时根据业务需要也可以增加一些部门；根据部门职务要求可以添加、修改、删除和查询一些角色。通过权限管理，将系统的用户划分为不同级别，增加了系统的信息安全性。基价管理是系统进行成本管理的基础，其数据由于是预算管理的核心数据，需要进行加密处理，而且查看、新建和修改等操作需要用户具有一定的权限。预算管理系统将具有对人员、资源进行基础价格的管理，对项目执行过程的开支与预算间的比对和后期费用的进一步分析计算等能力。系统数据的安全性将系统中的具有较高的保密性、关键数据例如用户信息、资源基价、项目配置等信息采取加密保护。
[Abstract]:One of the strategic strategies of the enterprise is cost budget management. The main purpose of the cost budget management is to control profits, achieve the target, and make a comprehensive and detailed budget before the implementation of the project. The budget tracking and implementation results of the implementation process are analyzed, the budget is evaluated, and a comprehensive control and management system of the cost and profit is constructed, and the after-account of the company management is transformed into the pre-budget and in-process control. In order to reduce the operating risk of enterprises and make the business activities under the control of budget management in an orderly manner. Cost budget management, as an important control tool in the implementation of enterprise strategy, aims at profit oriented enterprise projects, implements comprehensive budget management, provides comprehensive budget preparation, budget tracking and budget analysis, To effectively establish a management and control system In order to achieve the goal of high cohesion and low coupling in software design, this system makes full use of the traditional three-tier architecture design idea in the design idea and innovates constantly on its basis. At the same time, the advantages of B / S development mode are fully utilized in the development mode. In view of this system, we adopt WCF RIA service instead of traditional Web service in the service layer. Its main advantage is that WCF service not only encrypts the transmitted data in the time of data transmission, At the same time, the client can use asynchronous operation when calling WCF service, which improves the efficiency of data processing. In the data access layer, we use Linq To Entity technology to encapsulate the data to be operated, which is used to optimize the ADO.NET access technology in the traditional three-tier architecture. On the one hand, we avoid the injection attack of SQL statements. At the same time, the data that it will deal with is encapsulated into entity, which reduces the pressure of data processing brought by the server due to frequent database access, and improves the efficiency of data processing by the server. The front desk uses Silverlight technology to implement cross-platform cross-browser support Microsoft and Apple's various operating systems and Internet Explorer Firefox and other popular browsing software. The system can meet the needs of project budget management and provide professional solutions according to the individual budget management requirements of enterprises. The main functions of the system include personnel management, authority management, base price management, project management and data security module. Personnel management is used to manage human resources in the system, to modify, delete and query the existing departments according to the needs of the company, and to add some departments according to the needs of the business. You can add, modify, delete, and query some roles according to department job requirements. The users of the system are divided into different levels by privilege management, and the information security of the system is increased. The base price management is the basis of the cost management of the system. Because the data is the core data of the budget management, it needs to be encrypted and processed, and the operation such as viewing, creating and modifying need the user to have certain authority. The budget management system will have the ability to manage the basic price of personnel and resources, the comparison between the expenditure and budget of the project execution process and the further analysis and calculation of the later cost. The security of the system data makes the information in the system have high confidentiality. The key data such as user information, resource base price, item configuration and so on are protected by encryption.
