The correct option is "DataView". A DataView provides a flexible way to sort and filter data from a DataTable or a DataSet. By binding the DataGridView to a DataView that is associated with the dataset or table, users can interactively sort and filter the data displayed in the DataGridView.

The correct option is 'DataContext'. In LINQ to SQL, the DataContext class is responsible for connecting to the database and managing the objects retrieved from it. It acts as a bridge between the database and the .NET objects, allowing you to perform Create, Read, Update, and Delete (CRUD) operations on the database using LINQ queries and methods.

Parameters in non-query commands of ADO.NET are used to provide values dynamically to the command, helping in executing parameterized queries to interact with the database securely and efficiently.

Table Splitting in Entity Framework allows an entity to be mapped to multiple tables with a one-to-one relationship, where each table represents a subset of the entity's properties. This is useful when dealing with large entities or when certain properties should be stored separately for optimization purposes. Entity Splitting, on the other hand, involves mapping a single entity to multiple tables based on its properties, but with each table containing different sets of properties belonging to the same entity. This allows for more granular control over the database schema and can be beneficial in scenarios where certain properties are rarely accessed or updated separately from the main entity.

The correct option is CommandTimeout. In ADO.NET, the CommandTimeout property of a command object allows you to specify the maximum amount of time (in seconds) that a command can execute before it is terminated. This property is useful in scenarios where you want to control the execution time of commands, preventing long-running queries from affecting application performance or causing timeouts.

A DataAdapter in ADO.NET primarily serves two key functions: reading data from a database and populating a DataSet. This involves fetching data from the database based on a provided SQL query or command and then filling the DataSet with the retrieved data. This allows for disconnected data access in ADO.NET, enabling applications to work with data locally within the DataSet.

In LINQ to Entities, the "Include" method is used to eagerly load related data, which can help optimize performance by reducing the number of database queries executed.

The role of the Update method in a DataAdapter is to propagate changes made within a DataSet back to the underlying database. After modifying data within the local DataSet, such as adding, updating, or deleting rows, the Update method is called to synchronize these changes with the corresponding data in the database. This involves generating and executing appropriate SQL statements, such as INSERT, UPDATE, and DELETE, to reflect the modifications made in the DataSet back to the relevant database tables. By invoking the Update method, the DataAdapter ensures consistency between the application's data and the database, facilitating data persistence and integrity.

The DataMember property in data binding is used to specify the name of the data source column to which a UI control is bound. It indicates which column from the data source should be displayed or manipulated in the UI control, facilitating proper data representation and interaction in WinForms applications.

The ExecuteNonQuery method in ADO.NET returns the number of rows affected by the command, typically used with INSERT, UPDATE, DELETE queries. It does not return a result set or a scalar value. If there's an error, it may throw an exception.
