Research And Design On Data Management System For Train Diagram

The train diagram is a integrated plan of railway transportation, and is the base of railway orgnization work .Train diagram computerization is an important measure for marketing railway transportation. With the efforts of the railway managers and researchers, in our country it has maken great progress on the research of Computer Making Train Diagram, Most of the railway bureau have been applying it. Now the research on Computer Making Train Diagram has met the requirement of practical work, taking one with another, it wants to be studied deeply. For the Data Management System of Train Diagram, the part of the Train Diagram System, it' s the same. In our country, only the Computerized Train Diagram System has provided train diagram data management function. But the data, which is numerous and distributed, should be efficiently managed and used, and should provide effective means for train diagram management. We have no systemic and integrated research on it. Based on the system idea and design means of management information system, the dissertation has carried on the research and design of the Data Management System for Train Diagram.The main research contents are as follows:1. System analysis on the Data Management System for Train Diagram.2. Discussing the structure of the Data Management System lor Train Diagram, and proposing a web-based distributed application settlement scheme which bring convenience to the users.3. The structure design has been underway to the train diagram database on the basis of relationship database rules. And the concrete implementation scheme of Train Diagram distributed database has been analyzed and designed. Further more, discussing the modes of data distribution and location of the Train Diagram Distributed Database.4. System design and function design, which can provide kinds ol'information services for the train diagram management, have been carried on to the Data Management System for Train Diagram.5. Scheme design has been performed to the implementation of the Data Management System for Train Diagram, and it has thoroughly discussed the process of building the Train Diagram distributed database.
