Before writing the data Layer D layer when there are many SQL statements, how to omit the tedious SQL statements, Microsoft provides a good way-Entity Framework-entity framwork. An object mapping mechanism that supports. NET developers use domain-specific objects to come out of relational data, eliminating the need for

Entity Framework basics, entityframeworkOverview Entity Framework (EF) is another product specifically implemented by Microsoft ORM. This blog will briefly introduce it. As for its deep-seated usage, You can query the corresponding operation manual. This article is only an entry point. Relationship between

Both LINQ to SQL and the Entity Framework are object-relational mapping techniques that contain LINQ functionality. The essential difference between them is that EF does a better job of decoupling the database schema from the type of our query. With EF, the object we're querying is no longer a C # class that exactly corresponds to the database schema, but rather a higher-level abstraction: the

, and are not intruded by other frameworks. PO PO refers to a persistent object (persistant object ). The persistent object must actually correspond to the entity in the database, so it is different from POJO. For example, POJO is created by new and recycled by GC. However, the persistent object is created in the insert database and deleted by the delete database. Basically, the lifecycle of persistent objects is closely related to databases. In addit

On the one hand, I want to talk about the starting point of my article series, and on the other hand, I want to talk about the writing ideas

yet launched a similar framework, and still relies on ado.net, the traditional data access tool. It is estimated that Microsoft also heard complaints from programmers, so from a objectspace (ObjectSpace) from one to 2005 years early. Proposed that the concept of the application being able to connect to and access the database in a fully object-based way, with a technical concept similar to that of NHibernate, was finally released in 2008 Ado.net

Organization (not data storage. Another major goal of EDM development is to become a core data model for developers and server technology suites in Microsoft. By using a core data model, application maintenance is simplified. After achieving this goal, EDM can play a role, not only based on ADO.
