程序设计 设计需求
数据同步是分布式系统常常需要考虑的问题,即把分散的数据收集在一起,进行汇总统计。例如,耐克在全球均有分店,假如总店需要掌握分店的销售信息,就需要把分店的销售数据同步到总店。
目前主流数据库主要有两个:SQL Server和Oracle。对于Oracle数据库,有着比较成熟的同步技术,但SQL数据库则没有太好的解决方案,虽然已经有公司研发了同步程序,但是价格过于昂贵。
同时,数据库同步技术是一种常用技术,因此有必要开发出一套独立的数据库同步系统,避免重复劳动。
综上需求,特提出“SQL Server数据库同步系统”开发。
运行环境程序采用.NET 4.0开发,因此只能运行于Windows操作系统,同时需要.NET Framwork 4.0的支持。
程序中使用了SQLite本地数据库系统,香港服务器,但已经自行支持,无需安装其他组件。
程序针对SQL Server数据库开发,因此只支持SQL Server数据库,目前已知支持SQL Server 2003、SQL Server 2005、SQL Server 2008。
技术内幕回复超100公布 哈哈~~~
程序使用说明 系统部署示意图
本系统分为客户端和服务器两个部分,其中客户端承担了系统绝大数事务,服务器只是简单的执行客户端传送的命令,属于典型的C/S胖客户端瘦服务器模式。这样设计的目的是为了减轻服务器的压力,让系统更加流畅。
客户端负责采集分布数据库中的数据,然后汇总到服务器。客户端需要配置的数据库连接字符串是指分布数据库的连接字符串,连接成功后才可以向主数据库同步数据。例如,有A、B、C三个分布数据库,需要把数据汇总到D数据库,那么需要三个客户端,分别连接A、B、C数据库,客户端运行在哪无所谓,只要能连接数据库即可。
主页说明
主页显示一些公共信息。
程序启动日期有助于您分析日志同步状况;
扫描引擎、同步引擎是本系统两大核心引擎,扫描引擎负责获取分布数据库的数据变动,同步引擎负责向服务器发送需要同步的数据。如果数据库连接字符串未设置,引擎不会开启,否则,引擎自动开启,无需人工干预。
数据库占用空间是指程序本地的SQLite数据库占用空间,由于长期使用会有大量日志信息,占用过大空间会使程序效率降低,可以及时清理。清理界面如下:
选择好要清除的日志类型,然后选择日期,提交后会清除该日期之前的所有记录。
活动日志说明
该页面可以查询程序的活动状况,以日期查询可以显示某个日期的记录。
程序活动日志是扫描记录,详细记录了扫描信息。
