Final answer:
ADO.NET allows database access using ODBC, OLEDB, and XML, providing versatility in connecting to different databases and handling data.
Step-by-step explanation:
ADO.NET provides features for accessing traditional databases like SQL Server as well as databases, which are accessed using ODBC, OLEDB, and XML. These options enable ADO.NET to connect to various types of data sources, making it a versatile tool for developers.
Specifically, ADO.NET uses ODBC and OLEDB as data providers for different databases, allowing it to work with many database systems. XML is used in ADO.NET for data representation and manipulation, and DataSets, which can be considered an in-memory representation of data that can work with data sources including XML.
OLEDB (Object Linking and Embedding Database) is a Microsoft technology that allows accessing different databases using a common set of interfaces. XML (eXtensible Markup Language) can be used to access and store data from various sources in a structured format.
