This article mainly explains "ADO. NET architecture how to understand," interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn how to understand ADO. NET architecture.
XML technology has been supported by many software platforms and database manufacturers because XML data can be integrated with a variety of backend (database) sources through middle-tier agents. Microsoft's. NET provides a powerful and fast development tool-C#around XML, which has *** high development efficiency. Especially in XML and ADO. NET programming, relational data and XML are combined in. NET framework through tight integration between XML classes and ADO. NET.
ADO. NET architecture
ADO. NET is composed of a series of database-related classes and interfaces, and its cornerstone is XML technology. ADO. NET can not only access data in relational database, but also access hierarchical XML data.
ADO. NET provides two modes of data access: Connected and Disconnected. Connection patterns exist in ADO technology, while non-connection patterns exist only in the ADO. NET architecture. Non-connected mode provides greater scalability and flexibility for applications than traditional database access mode.
In this pattern, once an application obtains the required data from a data source, it disconnects the original data source and stores the obtained data in main memory as tables in a relational database. After the application processes the data, it takes a connection to the original data source and completes the update.
There is also a very important part of the ADO. NET architecture, namely the Data Provider object, which is a prerequisite for accessing databases. It enables operations on the actual database, the results of which are either processed directly in connection mode or corresponding data set objects are generated. NET Data Provider is the smallest possible layer between the data source and the application to improve performance without sacrificing functionality.
At this point, I believe that we have a deeper understanding of "ADO. NET architecture," may wish to actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
