备注

The Runtime namespace contains classes and base classes that offer an intuitive, object-oriented interface to Business Data Catalog client applications.

TheIEntityInstance interface is the most useful object you will work with in the Runtime namespace. It abstracts the underlying data sources and insulates the clients from having to learn application-specific coding paradigms, and allows them to access all business applications in a single, simplified way. It is because of the IEntityInstance interface that you can work with a row of data from a database in just the same way as working with a complex .NET structure returned by a Web service.
