Explain a bit more

modified data adapter.Update(dataset, "Customers");

Example code

SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM Customers", connection); SqlCommandBuilder commandBuilder = new SqlCommandBuilder(adapter); // Automatically generates insert, update, delete commands DataSet dataset = new DataSet(); adapter.Fill(dataset, "Customers"); // Modify data in the DataSet dataset.Tables["Customers"].Rows[0]["CustomerName"] = "New Name"; // Update the database with the modified data adapter.Update(dataset, "Customers");

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
