Research on Autogeneration of MFC Property page in Digital Zijin

“:数字紫金”中涉及大量的属性数据,如何对大量的属性数据进行有效管理,成为数据管理中的一个重要问题。自动创建模块可以实现专题数据录入界面的自动创建,并在数据库及其用户之间建立接口,实现对数据库的访问。

Autogeneration of MFC property page requires a new attitude toward problem solving. It is commonly believed that it will be efficient to perform under the control of programming than to operate manually. Data collection,input,access are the basis of DM (Dig- ital Mine). In digital Zijin,how to manage and maintain the attribute data plays an important part to data management. Autocreate module handles the tasks associated with creating,accessing and maintaining data base records. It establishes a user interface between the data base and the users of the database.MFC property page provides a user interface to access to the database. Autocreate module involves transforming the raw data to attribute data,which is compatible with DBMS such as ORACLE,and then creating property page. It can organize,process,and present the selected data elements from the data base. The host program Visual C++ 6.0 can provide the user re- source interface. The ADO and the embedded SQL accomplish the powerful and easy-to-understand logic for navigating the database to retrieve the various combinations of data required. In short,the module will manage the stored data items and assemble the needed items from the common data base in response to the quires of those who are not programmers. The browse through the data base is one of the most important tasks to undertake,ADORecordset class promises to significantly work. Data independence,integrity and security have been taken into account,lest the modification of the structure of database affect the application. In this case,functions are defined to safeguard the data against invalid alteration or destruction. The database transaction offers more to complete all the updates.
