C # winform Development Series-ADO. net

ADO. net name originated from ADO (ActiveX Data Objects), which is a broad class group used to access data in the past Microsoft technology. ADO is used. net name, because Microsoft, you want to indicate that this is in.. NET programming environment.

It provides platform interoperability and Scalable Data Access. Ado. Net enhances the support for non-connection programming modes and supports rich XML. Since the transmitted data is in XML format, any application that can read the XML formatProgramCan process data. In fact, components that accept data are not necessarily ADO. NET components. They can be a Microsoft Visual Studio-based solution or any application running on other platforms.

ADO. NET is an object-oriented class library used to interact with data sources. Generally, the data source is a database, but it can also be a text file, an Excel table or an XML file.

Ado. Net allows interaction with different types of data sources and databases. However, there is not a series of classes related to this to complete such work. Because different data sources adopt different protocols, different data sources must adopt corresponding protocols. Some old-fashioned data sources use the ODBC protocol, and many new data sources use the oledb protocol. Now more data sources are available. net ADO.. Net class library.

ADO. NET provides public methods for interacting with data sources, but uses a set of different class libraries for different data sources. These class libraries are called data providers and are usually named based on the protocols used to interact with them and the data source type. Table 1 contains some common data providers, the API prefixes they use, and data source types that allow interaction.
