particular data engine or storage schema. You can change the mapping between the conceptual model and the storage-specific schema without changing the application code. Developers can use a consistent Application object model that can be mapped to various storage schemas, which may be implemented in different database management systems. Multiple conceptual models can be mapped to the same storage schema. Language-Integrated Query support provides a query with compile-time syntax validation for

The Entity Framework is an exciting new technology developed for Ado.net. It enables developers to view data using logical models rather than physical models, and provides greater flexibility. The core of the Entity Framework is the Entity Data Model (EDM). An EDM defines the entity types, relationships, and containers that developers interact with through code. The Entity Framework maps these elements to

What is the Entity Framework (hereinafter referred to as EF)? The EF (Entity Framework) is a set of technologies in ADO that support the development of data-oriented software applications and is an ORM framework for Microsoft. ORM (Object Relational Mapping Framework): Refers to the transformation of the object-oriented object model and the data structure of the relational database.That's an official explanation, you know? I understand that business entities behave as objects in memory, in the d

Framework 1) Introduction to data access context objects From the code above, we can see that the data access context object SqlserverContext can interact directly with the database, and the table object can be added, deleted, modified, and queried, so how is this class? Why is this feature available? Let's take a look at its code. The class code of SqlserverContext is as follows (the code is automatically generated ). public partial class SqlserverContext : DbContext { public Sql

Translated from Euclidean Distance matrices:essential theory, algorithms, and applicationsThe EDMS is the average distance matrix between points. The aim of this paper is to introduce the application of EMD in the field of signal processing and show how the EDM is used to design the algorithm-repairing and de-noising the distance data. At the same time, the position calibration of the microphone (microphone position calibration), ultrasonic tomography

Model Browser:In the previous chapters, we created the first Entity Data Model for schools. But the EDM designer does not fully display all the objects that he created. It only displays the selected tables and views in the database.The Model Browser can display information about all the objects and functions created by the EDM. Right-click the EDM designer and se

The design of the Entity framework preserves high scalability in many places. One of its most important improvements is the flexibility of its mapping definition. As can be seen from the diagram, the Entity Framework can be used to fully define the entities that are mapped to the database table and use the entity directly fo

data is stored in the database. The table that is used to generate the view is called the base table for that view. One view can also be generated from another view.The definition of the view exists in the database, and the data associated with this definition is not stored in the database. The data you see through the view is stored in the base table.The view looks very much like the physical table of the database, and it operates like any other table. When you modify data through a view, you
