Design and Implementation of Information Management System for Enterprise

Abstract

With the rapid development of economic construction and the further development of enterprise information, computer and network technology are gradually applied to enterprises to improve efficiency and quality, and information management is an important part of modern enterprise management, so the design and implementation of enterprise information management system is important. Firstly, this paper describes the feasibility analysis of enterprise information management systems, including technical feasibility, economic feasibility and operational feasibility; secondly, studies the technical framework for the design of enterprise information management systems, mainly based on the .Net three-layer framework; finally describes the functional design of each module in the system. Analysis and design of enterprise information management system solves the common problems faced in the process of development and growth of enterprise, improving work efficiency and reducing operating costs. Introduction Under the background of information era, this office method by the paper as a medium has been unable to adapt to the demands of the era, for enterprises, which spent even more human and material resources, follow the development of era, is bound to adopt computer mode to manage information. Enterprise information management is that enterprise in order to maximize fully use of existing resources, strives to improve the quality of production and operation, all activities which in order to maximize obtain the economic benefits as the purpose, the process of approach implementing. In this process, business operators according to their enterprises characteristics continually to summarize, summarize, improving management and methods, trying to reach the harmony of entire enterprise's internal and external environment [1]. Information management system for enterprise (EMS) is a management system that uses of modern management ideas and methods, computer as a carrier, using computer software and network communication technology, in the process of production, management and decision-making collecting, storing, processing and analyzing a variety of information, to help companies process daily businesses until decision alternatives developed and the work optimized, as well as tracking, monitoring, controlling and regulating [2]. In general enterprise information management system consists of two parts that is office class and business systems, has five properties, including characteristics of industry experts and practical application characteristics, systematic and holistic, accumulation and sharing of history knowledge, and decision-making supportive and dynamic characteristics adapt to information changes. A complete enterprise information management system has a good support and protection role for production and business activities of enterprises, specifically shows in the various departments within the enterprise clear responsibilities, collaboration, achieves paperless office, adjust and optimize the internal departments, make accurate predictions for the market development, etc. [3].

The authors Published by Atlantis Press 56 Feasibility Analysis Feasibility analysis of a project mainly includes several aspects, such as the necessity, feasibility, and rationality and so on. Mainly explore the possibility and necessity of solving the problem, try to high-efficiency models and lower costs to estimate whether can be solved. Feasibility analysis primarily uses large amounts of data, information and other items of information to evaluate the feasibility of project created, there are several factors, namely the analysis method is comprehensive, system; second, economic efficiency as the core; third is to fully take into account other factors that could affect the project [4]. This paper mainly analyses three aspects that is the economic feasibility, technical feasibility and operational feasibility. Economic feasibility mainly measures the value of the project from the perspective of resource allocation, perform cost estimates and revenue estimates, depending on whether the economic benefits of the system can exceed the cost required to develop and maintain, as well as part of the social benefit needs experience to estimate. In the system design and operation, in addition to the server requires a little higher, the terminal equipment is not very expensive. Function needed by system is not more so developed up is simple, short development cycle, easy to learn, training of personnel funds will not be many, so the aspect of economic is feasible. Technical feasibility mainly from the technical point of implementation rationally design technical solutions, and make comparison and evaluation. Research on project technical feasibility of different industries and the depth varies greatly. This system uses the ASP.NET development. ASP.NET framework is based on a common language of the program running on the server, greatly improving the efficiency, because it is compiled based on the common language runtime, so it has a powerful and adaptable, also easy to learn, efficient and manageable [5]; Therefore, this paper studied the enterprise information management system with technical feasibility. Operational feasibility mainly analysis two points, from the user point, rational functional module design and convenient operation, fully meet the needs of users; from the administrator perspective, rational functional modules design facilitates internal management for system administrator. User interface design of the system is relatively simple, user-friendly use, company's employees through a brief training will be able to independently use of the system. Therefore, in terms of the operation, development of the system is feasible [6]. Technical Framework Design The another goal of framework design is that guarantee the scalability of system requirements for late, because with the continuous development of business and technology, the expansion of the system is essential, so in the process of system design, the goals of system architecture design include the following several aspects: (1) reasonable, each system has its own characteristics, has its own unique features and achieve results, in the design should not blindly pursue the new structure and new technologies, but to meet its own, to select the most suitable; (2) reuse, in the development appropriately pursuit the reusing between components and design patterns can greatly shorten the development cycle; (3) maintainability, architecture design need to rationally use theoretical knowledge of design patterns, to follow high cohesion, low coupling design thinking, enhance the maintainability of the code. (4) The scalability and portability; (5) performance, which is one of the core of a mature framework available, for long service and support a large number of access and speed of response is particularly important; (6) security, the framework design must be introduced NSPA access authentication mechanism [7]. The development of system using .Net three-tier structure, each business function is divided into three levels, the uppermost layer is the user layer, it facing the system user, providing visibility, actionable, friendly functional interface, users do not care these functions are how to achieve; the middle layer is business logic layer, the layer is mainly obtains the data input by user in the interface, by the business logic judgment, or calculating the data in the database, to a certain form feedback to the user interface, for users to browse, it can be said, business logic layer mainly
