摘    要:对于复杂的地质属性数据,使用常规的数据库数据模型,需要多界面录入数据,要耗费大量时间在界面的切换上,培训使用系统困难,另外,系统完成封装后,模型和界面就被固定,无法做必要的实时扩充或更改,使用数据字典技术,数据逆向规范化技术和数据挖掘技术支持下的动态数据模型,并把数据录入模型与数据存储模型分离可以很好地解决以上问题,提高了系统的实用性,适应性和生命力。

关 键 词:动态数据模型  数据库  地质填图  计算机辅助

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.
Keywords:data model  dynamic data model  database  geological mapping  computer-aided mapping system
