Design And Implementation Of TieMei Group Coal Sales Analysis Forecast System

With China's economic tells the development,information technology increasingly popular in China,all walks of life have entered the informationization management period,there is no exception for iron coal group.The number of coal enterprises in China,so the competition between coal enterprises are more intense,in order to solve this problem,the system will be the iron coal group coal sales forecast information as the theme,research information management system of a set of scientific,efficient,analysis and forecast of this iron coal group sales,improve the competitiveness of enterprises.In the process of the study of this system,the system adopts the framework and function of Java programming language,J2EE technology and MVC framework of the whole system development,it also uses the Oracle database to store the system data.Systematic study fully follow the principles of software engineering,firstly,the analysis of iron coal group coal sales forecasting research background and research significance system are analyzed,and the system research at home and abroad are discussed.After completion of the above work,the relevant requirements of the system are analyzed in detail,and the combination of the system needs analysis,respectively,is designed and implemented in the sales contract,sales planning module,module of sales forecast module and management module of sales calls.The sales contract module includes the contract review and approval,contract data tracking,document management and the development of the contract and the contract signed four sub function;sales plan module comprises a sales plan,sales plan,sales audit changes price development and sales plan for approval of four sub functions;sales forecast module contains billing real-time monitoring,statistics,ticket sales control machine survival statistics and sales forecast,four sub functions;maintenance of five sub functions of sales management module contains a single call in advance,loading notice maintenance,delivery quality inspection single maintenance,railway maintenance and requisition of the big ticket.The study of this system,the information technology into the coal sales management,statistical analysis of sales of coal,coal sales trend forecast,solve the original manual operation of the hysteresis and blindness,and the phenomenon of coal production overcapacity,promote economic development,at the same time,the protection of China's coal resources play to a certain extent.Therefore,the analysis of iron coal group coal sales forecast management informationization imminent,the design and implementation of a complete set of iron coal group coal sales analysis and forecasting system has important significance.
