RSM是什么意思？

rsm, shorthand for ReslutSetMatrix, is a database-detached matrix, build using collection objects, and containing data from a given result set.

rsm solves the problem of result sets being connected to the database, and thus unable to "move around" in an application. rsm creates a serializable object based on the result set retrieved after a query was sent in the database.

Once you created your rsm, given a result set, you can close your database connection and still have all the information intact. You can then send the rsm around between an application's different layers and even through network.

简单解释下就是一种将数据库数据从数据库中提取分离出来的理念。从数据库提取出数据后，数据被序列化保存在应用程序中，比如C#的DataSet，而与数据库不再关联。这样保证了可以将序列化的数据在应用程序的不同层甚至在网络间进行传递，而不必考虑能否连接数据库。
