What is the difference between a DataTable and a DataView? Both DataTable and DataView are used to represent data in ADO.NET, but they have different purposes: ● DataTable: Represents a single table of data in-memory. It is a container for rows

nd columns, and it is used to hold data returned from the database.

Key Features:

• Can hold data from one table.
• Provides methods for data manipulation (e.g., adding, deleting, modifying

rows).

• Can be filled with data from a DataAdapter.

Example:

DataTable table = new DataTable();

table.Columns.Add("ID");

table.Columns.Add("Name");

table.Rows.Add(1, "Alice");

table.Rows.Add(2, "Bob");

• ● DataView: Provides a way to view and filter data from a DataTable without changing

the underlying data. It allows you to sort and filter the data dynamically.

Key Features:

• Acts as a view of a DataTable.
• Allows for sorting, filtering, and searching the data.
• It does not modify the underlying DataTable.

Example:

DataView view = new DataView(table);
view.RowFilter = "Name = 'Alice'";
view.Sort = "ID DESC";

• Summary:
• DataTable holds data, and DataView provides a dynamic view (filtering, sorting) of

the DataTable.
