Design And Realization Of Navigational Matters Management Information System Based On B/S Structure

As information age is coming, the information construction of civil aviation is becoming more and more important. Taking the development of the navigational matters information in CAFUC as example, this paper describes the design and implementation of the navigational matters management information system (NMMIS) based on Browser/Server(B/S) structure.The function of this paper can be described as follows:Firstly, the paper presents that how the new system gets the data from each service database system of the users' previous company effectively, and make sure the safety of the previous service system at the same time. It also can work as route by applying three-layer exchange functions on the main switchboard in the our design, in this way, it can solve the connection collision of the old and new service system in the right way; Taking VLAN technology to separate the old system and forbid the new system to access the data from the other service system so that the data can be protected.Secondly, applying the key technology of data real-time and synchronization in the differ-structure databases by taking ADO to deal with the database. It lowers the requirements for equipments and applications greatly, and considers all kinds of servers at the same time; we can use it more flexibly and conveniently.The structure of this paper is as shown as follows:The first chapter describes the structure of the navigational matters management information system, design aims and principles.The second chapter introduces the general frame, the module function design and the key technology related to the network system of the NMMIS in detail.The third chapter introduces the construction of the software and hardware platform of the system, and makes a concrete analysis with the selection of the database and installation of the system.The fourth chapter gives a brief introduction of the data synchronization program, and explains the functions of the data synchronization sub-system in the NMMIS. It presents a concretely analysis of the principle of the data synchronization program using ADO technology to design and realize data synchronization program in the NMMIS, and gives the technology difficulties in the data synchronization programming.The fifth chapter gives some application examples of the navigation information sub-system in the NMMIS.The sixth chapter summarizes the article and gives the direction of how to improve this system in the future.
