This article introduces you and then analyzes the features of ADO.NET and the new functions of ADO.NET. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

There is a lot to say about the features of ADO.NET, such as Microsoft's official data technology. ADO object is the medium used by the program development platform to communicate with OLE DB. The current version of ADO is ADO.NET. If it reaches critical mass, we will support it.

Unlike previous versions of ADO, which are designed to access databases, ADO.NET is designed for extensive data control, so it is more flexible and provides more functions than previous ADO. The emergence of ADO.NET features is not to replace ADO, but to provide more efficient data access. Microsoft provides an architecture that meets many needs through. NET technology, which is the .NET shared object class library.

This shared object class library not only covers the Windows API (Windows Application Programming Interface,Windows application design interface). Provides many of the objects and basic functions needed to write Windows programs. And provides more features and technologies; it also includes the objects and functions that we often use on different COM components In addition, ADO.NET also integrates XML, which makes it very easy to exchange data. Therefore, the architecture and new functions of ADO.NET are new technologies that can meet a wide range of data exchange needs, which is called ADO.NET.

ADO.NET features allow us to access all kinds of data quickly and easily. Traditional master-slave applications remain online with the data source when they are executed. However, in some cases, it is not necessary to stay online with the database, and it is a waste of system resources to keep online with the data source all the time. Sometimes we just need to simply retrieve the data, so we don't need to keep the data source online. ADO.NET is designed to be an architecture in which data processing is not always online, and applications work online with data sources only when they want to obtain or update data.

As a result, there are fewer links to be managed by the application; the data source does not have to stay online with the application all the time, and the performance increases as the load is reduced. However, there are some situations in which our application needs to stay online with the data source, such as the online reservation system; at this time, we can still use the data source featured by ADO.NET to stay online at any time.

This is the end of the analysis of the features of ADO.NET and the new functions of ADO.NET. I hope the above content can be of some help to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
