ADO.NET provides the ConflictHandling event to customize conflict resolution logic. This event allows developers to define custom conflict resolution strategies when updating data from a data source. By handling this event, developers can implement logic to resolve conflicts that arise when multiple users attempt to modify the same data concurrently.

Entity Framework supports CRUD operations which stand for Create, Read, Update, and Delete. These operations enable developers to interact with database records effectively.

When optimizing performance in Entity Framework applications, reviewing query execution plans and indexing strategies is crucial. These aspects directly affect how queries are executed against the database and how efficiently they utilize indexes. By optimizing query execution plans and indexing strategies, you can significantly improve the performance of database operations in your Entity Framework application. This involves analyzing the SQL queries generated by Entity Framework, ensuring appropriate indexing on database tables, and fine-tuning the database engine's execution plan to leverage indexes effectively.

One of the key advantages of the DataList control is that it supports multiple templates for item presentation. This feature allows you to define different layouts for different types of data items within the same control. For example, you can have separate templates for displaying header, footer, and individual data items, providing flexibility in the presentation.

The correct option is option 1, When you want to create a new DataTable from the DataView. The ToTable() method in ADO.NET is used to generate a new DataTable containing the same data as the DataView. This is helpful when you need to work with the DataView's data in a DataTable format for further processing or manipulation.

When interacting with an Oracle database in .NET applications, the appropriate data reader to use is the OracleDataReader. This specialized data reader is designed specifically for working with Oracle databases, providing efficient access to query results and handling Oracle-specific data types and features. Using the correct data reader ensures compatibility and optimal performance when retrieving data from an Oracle database.

Improving the performance of LINQ queries with multiple joins and filtering conditions involves using appropriate indexes on columns involved in joins and filters. This helps in optimizing data retrieval and processing, resulting in better query performance.

A stored procedure is a precompiled collection of one or more SQL statements which are stored in the database server. When you execute a stored procedure, you are actually running a precompiled execution plan, which can improve performance and security. They are commonly used to encapsulate complex business logic, enhance security by controlling access to data, and promote code reusability.

Connection pooling in ADO.NET offers better performance by reusing connections instead of creating new ones for each request. This reduces the overhead of establishing connections and can lead to significant performance improvements, especially in high-volume applications.

Data binding in DataGrid or DataGridView controls is crucial as it ensures that any modifications made to the underlying data are immediately reflected in the associated UI controls. This results in a more responsive and synchronized user interface, simplifying the development process and enhancing the overall user experience.
