元数据与元数据的数据有何区别?
Basically a DataSet is a collection of DataTables, possibly including relationships between the tables.

数据单是从数据来源检索的数据的中间点,是《反歧视法》的一个主要组成部分。 NET架构。 该数据表包括收集可数据识别的物体,这些物体可与数据传输物体相互连接。 你们也可以通过使用“独一无二”和“外国统治”物体,在数据表中实现数据的完整性。 关于与数据基物体合作的详情,见数据表、数据表和数据表(ADO.NET)。
因此,数据单本身并不包含数据,而数据总是在数据表内。 数据单基本上增加了元数据。
You could think of a Dataset as a database, within which there could be one or more tables. A DataTable would be one of the tables within that database.
So, in summary:
<>DataSet<->Database
<>可测量 <-> a table within a database.
