In this issue, the editor will bring you about the different types of ADO.NET applications. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

ADO.NET applications include easier design integration, expanded deployment options, more colorful login and personalized services, and better data access and synchronization, not so specifically designed for databases. ADO.NET aggregates all the classes that can be used for data processing. These classes present data container objects with typical database capabilities.

For example: indexing, sorting, browsing. Although ADO.NET is an important solution for .NET database applications, it shows more of a comprehensive design than just as database-centric as the ADO model. .

ADO .NET is very different from ADO. It is a new access programming model. When you start using ADO.NET applications, you will find that any ADO skills you have will be of great help in building effective programs and solving problems, and will help you move in a more flexible and secure direction in solving problems.

The ADO.NET application is not an improved version of ADO to adapt to the .NET infrastructure. When you slowly understand the syntax, code design and migration of ADO.NET applications, you will understand.

Data access in 1.NET

Access to data sources in ADO.NET is controlled by managed providers. Although there are two major differences between managed providers and OLE DB, they are very similar. First, the managed provider runs in the .NET environment, retrieving and displaying data through DataReader and DataTable .NET classes. Second, their architectures are relatively simple because they are optimized to adapt to .NET.

At this point, ADO.NET applications are divided into two different types of managed providers: one for SQL Server 7.0 or later, and the other for all OLE DB providers that you may have installed. Although the classes used in the two managed providers are different, they both follow similar naming patterns. Except for the prefix, all other names are the same. In the former case, the prefix is SQL, and the latter is ADO.

You need to use the SQL class to access the SQL Server table, because the SQL class skips the middle tier rendered by the OLE DB provider and goes directly to the internal API of the database server. The ADO class is the. Net interface at the top of the OLE DB provider, using the COM Interop bridge to work.

These are the different types of ADO.NET applications that Xiaobian shares with you. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
