deleted, rather than actually deleting records from the database. For example, you might not want to hard delete a user record from a database because it is associated with many other tables. In order to achieve the purpose of soft deletion we can implement the interface Isoftdelete: public interface isoftdelete{ bool isdeleted {get; set;} } The ABP realizes the soft deletion mode which is used in the Open box.

What is the entity FrameworkThe Entity framework is an object-relational mapping O/RM framework.The Entity Framework allows developers to manipulate relational data (relational) as if they were the domain object (domain-specific objects). The
as usage data and usage patterns evolve. with this in mind, the Entity Framework is designed around exposing an application-oriented data model that is loosely coupled, and may differ significantly, from your existing database schema. for example, you can map a single class (or "entity") to multiple tables/views, or map multiple classes to the same table/view. y
In the previous article, we created an MVC application using the entity Framework and SQL Server LocalDB, and used it to store and display data. In this article, you will modify the CRUD (create, read, update, delete) code that is automatically created by the MVC framework.Note: Typically, we create an abstraction layer between the controller and the data access layer to implement the warehousing model, and
The previous article introduced several common concepts of EF4: context, SSDL, CSDL, mapping, entity, entityset, property, container, association, and realationship. Because these concepts will be used later, it is time to understand these concepts after reading the overview section. In EF4, how to perform in-depth knowledge such as status tracking, multi-thread management, data synchronization, and memory models of entities and
Some time ago there were many Article This article introduces and analyzes LINQ to SQL. It can be said that it is a simple implementation of ORM, which is a problem that Microsoft has unbalanced impedance between data and objects. C #3.0 introduces some new features, such as extension method, Lambda expression, and anonymous type. In fact, these new features are used to serve LINQ. Program In the past, I was freed from writing a large number of SQL query
