这并不要紧,因为使用非类型化数据集时,如果基础架构发生改变,您仍然可能必须更改一些客户端代码。
This is not a big deal because when you use an untyped DataSet you would still likely have to change some client code if the underlying schema changes.
TClientDataSet 只是在客户端的一个内存表(in-memory table),对该数据集的更改将不会自动保存。
The TClientDataSet is only an in-memory table at the client side, and changes to this dataset will not be saved automatically.
该数据库标签能够快速地连接数据库,访问数据库表格记录,返回数据集,最后显示在客户端的JSP页面中。
The database tag can rapidly connect database, visit database form and return data set, at last show data in client's JSP pages.
