实现的数据库io缓存模拟程序，读入五万个地址和读写标志，输出命中率，io次数等(Io caching implemented simulation program that reads fifty thousand addresses and write flag output hits, io number, etc.)

VFP数据库继承了以往传统数据库的优点，是采用了面向对象的程序设计思想和可视化的编程工具，操作简单、易学，极大的方便了软件的开发。人们在使用它作为开发工具时，可以高效的开发出全新的可视化图形界面应用程序。(VFP database inherits the advantages of traditional databases, is the use of object-oriented program design and visual programming tools, simple operation, easy to learn, which greatly facilitates the software development. People use it as a development tool, you can efficiently develop a new visual GUI applications.)

该例程参考《Visual C++开发修行实录》，为ADO访问Access数据库的例程，其中详细介绍了ADO访问数据库的步骤，以及查询、修改、删除等SQL语言的使用。(Refer to the routine Visual C++ development practice record , as the ado access access routines, which details the steps of ADO to access the , and query, modify, delete SQL language use. )

在MFC种利用ADO进行数据库的处理，也可以用ODBC来做。(Use ADO in MFC to test the SQL.)

用数据库的方式操作excel文件，包括了读取文件的表名，字段名和数据，有详细的注释(Operate with the database excel documents, including a table read from the file name, field names and data have detailed notes)

VC++ 通过ODBC读写Excel文件 VC++ 直接通过ODBC操作读写Excel表格文件的程序，附上源代码，程序没有其它功能，就这一个读写EXCEL的功能，可以VC6下编译通过(VC++ to read and write Excel files via ODBC VC++ ODBC operations directly through the program to read and write Excel spreadsheet files, attach the source code, no other program features a reading and writing EXCEL on this feature, you can compile under VC6)

说明：  一个国外人用Microsoft Visual C++开发的小数据库。可以看看。这是他工作的东西哦。(a foreign people using Microsoft Visual C development of a small database. Look. This is the work of the things he Oh.)

物资管理系统，实现物资入库、出库、物资信息的增删查改等。(Materials management system, implementation of materials storage, a library, information material, etc. check the additions and deletions.)

该代码展示了MFC连接数据库ACCESS的方法，采用的ADO接口，特别适合初学者学习(The code shows the MFC method to connect to the database ACCESS using ADO interface, particularly suitable for beginners to learn)
