What are managed providers

ADO.NET enforces a standardized and unified interface for accessing data, promoting a simplified and streamlined data access architecture. This approach often yields improved performance without compromising functional capabilities.

Within the .NET Framework, there are two default Managed Providers: the SQL Managed Provider and the OleDb Managed Provider. The SQL Managed Provider is specifically designed to interact with Microsoft SQL Server databases, while the OleDb Managed Provider caters to data sources that utilize OleDb connectors. The SQL Server managed provider includes essential objects such as SqlConnection, SqlCommand, and SqlDataReader, while the OLE DB managed provider offers a similar set of objects with names prefixed by OleDb instead of Sql. Despite the differences in naming, the programming model remains essentially the same. These providers abstract the underlying functionality and efficiently handle complex operations behind the scenes. Notably, both providers reside within the System.Data namespace, emphasizing their cohesive integration within ADO.NET.
