The Ead Virtual Instrument System Design And Implementation

Along with the enrollment expansion of higher education, students'information management is becoming increasingly intricate. Catering management, especially, as a fundamental part of college logistics group, is confronted with higher challenges as the traditional manual processing of related information brings about tremendous waste in man power and material resources. This explains the modern college catering management system appeared in most colleges, highlighting the coexistence of varied regions, campuses, and multi catering industrial culture. The college catering management system proposed in this paper enables the realization of informationalization of college catering service operation, therefore promises better service, and more cost reduction.Dealing with the catering management system of the logistics group in Shanxi Normal University, this paper analyzes the software framework, expounds on the features and merits of .NET platform in software development, and introduces the common techniques and development models of .NET platform. UML modeling technique, multi techniques under .NET platform, and major techniques such as ASP.NET, ADO.NET, and Web Services etc. are introduced in this paper. Based on the above research, and in combination with the business requirement of the catering management system in the logistics group at Shanxi Normal University, this paper puts forward the design and development of a catering management system in college logistics group, based on .NET platform, so as to validate the practicability of .NET in small and medium-sized information operation systems, and discuss the implementation of Web Services technique in catering management systems.This system contains five functional modules, namely: canteen management, card management, warehouse management, finance management, and system management. The system is overall flexible and convenient to use in that it helps to solve problems involving all the procedures of the current catering management. The system helps the operator of school canteens to acquire first hand information of the price fluctuating, know about the costs and benefits, raise the work efficiency, accurately manage complex data such as storage and consignment, help administors to spot possible flaws, etc.Besides the above-mentioned catering management function, two other features of this system are highlighted in the following:1. Dynamic cost accounting. Cost keeping is fundamental in catering management due to the great variety of food and the dynamic fluctuating of prices. This system conducts cost accounting using tools such as diagrams.2. Development technique based on Web Services. This is a new NET development technique. A card reader needs to be linked for related card information in the account settlement webpage of the financial management system. Web Service simulated card reading is used in this system.
