【Abstract】 This paper briefly explained the purpose and the importance of establishing mineral reserve database either in a country or in a province,and pointed out that the system analysis and logical design must be carried out in accordance with the thinking methods of software engineering. The author thought that the certification of feasibility is not only the base of logical database design,but also effecting the process and the result of design. Through data analysis,the concepuual structure and the logical structure of mineral reserve database was designed to meet needs of the data relationships the user’s requirements,the retrieval and the statistical analysis in order to assure the quaity of database.On the basis of above mentioned work,the thinking of system design was drawn out to direct all of the project. The results were that the design had been implimented on the micral computer IBM-PC.and that metal mineral reserve database had been established in a provence,A tree-form hrareichical database will be gradually established in the future.更多还原
