创建基于MySQL、Redis和MongoDB数据库开发命令行新闻管理系统。设定管理员和新闻编辑两种身份，实现发表新闻、编辑新闻、删除新闻、增加用户和删除用户等功能。

使用Java实现数据库编程(北大青鸟java入门教程)

外卖叫餐系统，采用ACCESS数据库，有完整天的后台管理系统(Call takeaway meal system that uses ACCESS database, a complete management system for day background)

acess数据库中关于ADO控件和DATAgrid控件以及sql语言添加查询删除编辑等功能的实现(acess database in ADO controls and a DataGrid control, as well as the sql language query to delete editing functions )

连接MFC与SQL SERVER 2012数据库和（或）ACCESS数据库

实现即时将数据库信息推送web前台功能，需要数据库支持(Push Station instant messaging capabilities, database support)

二维码生成解读源码（支持汉字，有演示地址）

说明：  直接使用ADO操作ACCESS数据库，对于初学者来说是个不错的例子，类似的也可以操作SQL,ORACLE数据库（不用DSN）(use ADO directly ACCESS database operation for beginners is a good example of a similar operation could SQL, Oracle database (not DSN))

两个Access文件中的表进行比较，数据库编程源码，很好的参考资料。(The two files in the Access table comparing, database programming source code, a good reference.)

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)
