Which Ado.Net Class Provides A Disconnected Environment

Option B) Data Set is the Correct Answer

In ADO.NET, the classes that provide a disconnected environment for working with data are primarily the DataSet and DataTable classes. These classes allow you to work with data in-memory without a continuous connection to the database server, providing a disconnected or “offline” data manipulation capability.

1. DataSet: A DataSet is a disconnected, in-memory representation of a relational database. It can contain one or more DataTable objects, representing tables from the database. You can fill a DataSet with data from a database using a data adapter, manipulate the data within the DataSet, and later update changes back to the database if needed.
2. DataTable: A DataTable is a part of a DataSet and represents a single table from the database. You can think of it as a disconnected table. You can perform operations like querying, sorting, filtering, and updating data within a DataTable.
3. DataView: A DataView is not a class for disconnected data storage but rather a class for filtering and sorting data within a DataTable or a DataSet. It allows you to create different views of the same data without modifying the underlying data.
