The Research And Application Of The Data Reconstruction On Database Flctitious Machine

Foodstuff is vital for people even the country.And the foodstuff safety is the most important element of the country safety.Under the circumstance of the market economy system,the big enterprise storing cereal and oil has to manage efficiently,improve the economy benefit and meet the need of the people's life,at the same time,it is responsible for protecting foodstuff safety.It is of great importance to improve the informationization level of the enterprise.The informationization of the enterprise is that it uses widely and explores deeply by the modern information technology,such as Internet,computer,telecommunications to improve the level and efficiency of its production,management and making decision,which is beneficial to improve its economic benefit and key competence force.At the first stage of informationization,for the limit of the thinking,technology and other objective conditions,the built database is lack of entirety and forecast,some of them is built for different purposes at different stages,which is unavoidable for the database to have different standards and names.So it is very difficult for the enterprise to change the structure of the data,which has influenced the functions of the application programme.I analyze the database problem exsisted in the enterprises during building the informationization in the essay.And design a model of database virtual machine,it mainly resolves the problems as follows:To eliminate the naming conflicts and obtain uniform description of data structure according to the uniform data standard to make the data sharing among different applications come true;To ensure the logic independent of the application programme and data by building " mapping mechanism";To bulid up the practicability of data management by improving resolutions of "data class" of the initial data management technologies and enterprise requirement.The model is used in "Origin Data Management System"in Linqu Cereal and Oil Storing Enterprise in the essay and has made great effect in reconstructing database,improving management procedure,reducing management cost,improving economic efficiency and protecting protecting foodstuff safety.
