Abstract

Abstract

When we construct a database to store the complicated geological attribute data, we need many interfaces to input the data if we use the routine database data model. So it will be very difficult to input the data into right places and learn to use this kind of system. In addition, it is impossible to do some necessary change and expansion to the data structure and interface as soon as the system development is completed and the data model and the system interface are fixed. These problems can be solved by using the dynamic data model, which is established based on the data dictionary technique and data converse standardization technique, data digging technique and by separating the inputting data model and data storage model. As a result, the database built by using the dynamic data model can be more practicable, adjustable and vital to the system.
