Accepted Answer

A table in a database schema is often used to represent a entity, which is a general term for an abstract notion. object is a common name for in-memory data structures. A a thing an item, which is an instance of a entity type, is an object that represents an entity and is often mapped to a row in a database table (often mapped to a table).

The value A entity is a component of an EDM instance (Entity Data Model) is mapped to rows in one or more tables in the.NET Framework (3.5 SP1) by this value. A Customerentity kind, for instance, may map to a single Customer database table or it may extend to a CustomerPreferences table. You may use eSQL to access entities as if they were merely rows in database tables by using the EntityProvider. The theoretical layer is another name for the EDM model.

Entities are materialized as EDM-mapped objects in the range The item layer layer is a further layer that sits on top of the EDM model..

Popular Answer

A entity is anything that existing in and of itself, whether physically or not, really or hypothetically, concretely or abstractly. It needs not be of material existence.

An object is a region in memory that has a value and may be referred by an identifier in computer science.
