Economic Analysis Software’s Design and Implementation

 

Abstract: Economic forecasting plays increasingly important role in modern economic life. It is the basis for the policy of enterprises established, decision-making and planning; it is also an important element to improve the management level and the work plan.The system to a gas company in the 2001-2005 based on its historical data information. It realizes the company's statistical and analytical of operating history and the development of customer. Then it uses the economic mathematical methods based on the results of the analysis which is suitable for the operation of the historical data required to reach the projected results. First, give the detailed analysis of historical data which is based on the gas company data sheet 2001-2005; Second, do in-depth understanding of the existing economic forecasting methods ，combined with statistical mathematics knowledge; Third, database design. In order to transfer data from the database to facilitate later database, get the historical data from the table Excel to datebase MySQL; Fourth, the design of projection models.It should be based on economic forecasting methods and design Reasonable related prediction models; At last, give the discription of the inadequate place in the system and  some research ideas for the after working.
