The Design Of Cigarette Assistance Formulators' System

Database technology has formed solid rationale, mature commercial product and widespread application domain in half century time since it was bom, attracted more and more researchers join. It has already become the important constituent of advanced information technology, and it was the foundation and the core of modern computer information system and the computer application system. The design of database is directly related to the function of system.As a part of database design in "the cigarette assistance formulators' system project", this article analyzed and found out the advantage and disadvantage of system, and it also compared the characteristic after researching the theory of relational database designing system. On the basis of old database, a new one is built up. The design of this database that begins to normalization from low to high can make the structure more clear and simple, and it also reduce the abnormity and improve the capability of system. This database emphasized the use of history data on the basis of the data integrity and data consistence, when it deduced the network traffic. The use of user view simplified the user's manipulation and secured the data. At the same time, the design provided logical independece for the reconstruction of database.The goal of this database lies in the solution to the cigarette history formula information preservation, provides the basis for technical personnel's present formula, at the same time provides the data support to the formula product design mathematics model. The database establishment greatly degree eliminated the data non-uniformity which exists in the manual filing system, enhanced technical personnel's efficiency, after this system design implementation, not only satisfies cigarette personnel's request of present stage, but also provide the basic data for the digitized product assistance design of next step research and development.
