"The essential difference is that EF allows for stronger decoupling between
the database schema and the classes that you query. Instead of querying
classes that closely represent the database schema, you query a higher-level
abstraction described by an Entity Data Model. This offers extra
flexibility, but incurs a cost in both performance and simplicity.”
能给个example吗？ |
