blocks|key|791596|text|SQL+Notification+Services将允许您基于多种协议对应用程序进行数据库回调。一种实现方法是让通知服务在可访问的网络共享上创建(或修改)一个文件，并让桌面应用程序使用FileSystemWatcher进行反应。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|791597|有关Notification+Services的更多信息，请访问：http://technet.microsoft.com/en-us/library/aa226909(SQL.80).aspx|offset|length|791598|请注意，这可能是解决坚果类型问题的一种大锤方法。|791599|entityMap|0|LINK|mutability|MUTABLE|url|http://technet.microsoft.com/en-us/library/aa226909(SQL.80).aspx^0|0|X|1S|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

SQL Notification Services will allow you to have the database callback to an app based off a number of protocols. One method of implementation is to have the notification service create (or modify) a file on an accessible network share and have your desktop app react by using a FileSystemWatcher.

More information on Notification Services can be found at: <a href="http://technet.microsoft.com/en-us/library/aa226909(SQL.80).aspx" rel="nofollow noreferrer">http://technet.microsoft.com/en-us/library/aa226909(SQL.80).aspx</a>

Please note that this may be a sledgehammer approach to a nut type problem though.

blocks|key|791615|text|由于您使用的是SQL2005，因此可以使用SqlDependency来获得更改通知。请注意，您可以非常轻松地将其与System.Web.Caching.Cache一起使用，尽管它的名称空间运行just+fine+in+a+WinForms+app。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|791616|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldependency.aspx|1|http://msdn.microsoft.com/en-us/library/system.web.caching.cache.aspx|2|http://weblogs.asp.net/rosherove/archive/2003/08/12/23813.aspx^0|L|D|0|1L|O|1|2O|R|2|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]|$A|T|B|U|1|V]|$A|W|B|X|1|Y]]|C|$]]|$1|D|3|-4|5|6|7|Z|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]|N|$5|G|H|I|C|$J|O]]]]

Since you're on SQL2005, you can use a <a href="http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldependency.aspx" rel="nofollow noreferrer">SqlDependency</a> to be notified of changes. Note that you can use it pretty effortlessly with <a href="http://msdn.microsoft.com/en-us/library/system.web.caching.cache.aspx" rel="nofollow noreferrer">System.Web.Caching.Cache</a>, which, despite it's namespace runs <a href="http://weblogs.asp.net/rosherove/archive/2003/08/12/23813.aspx" rel="nofollow noreferrer">just fine in a WinForms app</a>.

blocks|key|3917552|text|这也可能是大材小用，但也许你可以实现某种缓存机制。也就是说，当数据写入数据库时，您可以同时对其进行缓存，而当您尝试从DB取回数据时，请首先检查缓存。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3917553|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This may also be overkill but maybe you could implement some sort of caching mechanism. That is, when the data is written to the database, you could cache it at the same time and when you're trying to fetch data back from the DB, check the cache first.

The solution we developed uses a database (sqlserver 2005) for persistence purposes, and thus, all updated data is saved to the database, instead of sent to the program.

I have a front-end (desktop) that currently keeps polling the database for updates that may happen anytime on some critical data, and I am not really a fan of database polling and wasted CPU cycles with work that is being redone uselessly.

Our manager doesn't seem to mind us polling the database. The amount of data is small (less than 100 records) and the interval is high (1 min), but I am a coder. I do. Is there a better way to accomplish a task of keeping the data on memory as synced as possible with the data on the database? The system is developed using C# 3.5.

我们开发的解决方案使用数据库(Sqlserver2005)进行持久化，因此，所有更新的数据都保存到数据库中，而不是发送到程序。我有一个前端(台式机)，它目前一直在轮询数据库，以获取一些关键数据随时可能发生的更新，而我并不是数据库轮询和浪费CPU周期的粉丝，因为这些工作被无用地重做了。我们的经理似乎不介意我们轮询数据库。...
