数据源：本实例使用的数据源在本章实例MyOd 联合开发网 - pudn.com

ssm学生信息管理系统(源码+数据库+文档)

本实例演示了利用DAO访问数据库的常用方法，并附带了所用的数据库course.mdb。(examples demonstrating the use of DAO Database Access commonly used methods, and the incidental use of the database course.mdb.)

使用Excel实现生成、打印数据库报表数据，VC++经典编程学习源码，很好的参考资料。(Use Excel to realize the generation, print database report data, VC++ classic learning programming source code, a good reference.)

MFC链接Access数据库，采用ADO数据库方式。(MFC link Access database using ADO database mode.)

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)

简单的记帐工具,没有调用数据库,非常适合学生进行安卓的学习(Accounting tools simple, do not call the database, very suitable for students learning for Android )

百度数据库中间层讲的主要有 MySQL数据库集群面临的问题 数据库中间层整体设计 数据库中间层主要功能模块和策略 数据库中间层应用 数据库中间层发展(Baidu middle layer of the main MySQL cluster problems The overall design of the middle layer of the Database middle layer main function modules and strategies Database middle tier application Database middle tier development)

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.)

1.基于数据库的升级，比FTP、HTTP模式，优点：在一台计算机上，多个不 同版本的程序可以同时使用，互不影响。不用另外配置FTP/HTTP服务器。 2.可自动压缩文件,然后上传,提高上传与下载速度.减轻基于数据库的升级 的速度问题. 3.支持一个数据库中多个模块同时使用. 4.支持一个模块有多个文件.(网上的只能一个文件), 你的软件最好为多个文件, 因为有的文件未改变,下载会跳过. 5.支持文件位置在不同的文件夹. 6.本“自动升级系统”,也可以自动升级(注:仅随新系统升级时升级!!!) 7.新程序上传到服务器为自动的,不需要人工上传。(网上的都得手工一个一个上传．) 8.新程序下载为自动的。(网上的也自动，但不强制下载，本程序强制下载．) 9.支持两个数据库中的该表同步: 可用于连锁系统, 总部升级, 分店都会自动 升级。(1. Based on the database upgrade, than FTP, HTTP mode, advantages: on one computer, many do not The same version of the program can be used independently of each other. Do not also configure FTP/HTTP server. 2. Can automatically compress files, then upload to improve upload and download speed. To reduce the upgrade based on database The speed. 3. To support a database of multiple modules simultaneously. 4. Support a module has more than one file. (Online only a file) Your software is best for multiple files, because some files are not changed, downloaded will be skipped. 5. Support the file location in a different folder. 6. The "automatic upgrade system" can also be automatically upgraded (Note: Only with the new system upgrade upgrade!!!) 7. The new program is uploaded to the server automatically, without manual uploads. (The Internet had to upload one by one by hand.) 8. The new download is automatic. (Also automatically online, but not mandatory download, download t)
