XML and ADO.NET Questions and Answers
XML and ADO.NET are vital technologies for data storage and communication in .NET programming. They frequently appear in programming questions and answers for companies like Capgemini, Wipro, and TCS. XML (Extensible Markup Language) provides a structured way to store and transport data, while ADO.NET enables database interaction using disconnected architecture. Understanding DataSets, DataTables, and XML parsing is key for handling real-time data efficiently. Practicing ADO.NET interview questions with answers helps strengthen your database and coding integration skills.
