LINQ is a querying language that allows querying of any data source, including collections of objects, databases, and XML files. It works by querying data sources that implement the IEnumerable<T> interface. LINQ can be used for in-memory data (LINQ to Objects), XML data (LINQ to XML), databases (LINQ to SQL, LINQ to Entities), and datasets (LINQ to DataSet). The architecture of LINQ includes language enhancements that enable querying, execution against different data sources, and type relationships between objects.

2. What is LINQ
• LINQ is a querying language feature and has a great power
of querying of any source of data.
• Data source could be the collections of objects. Database or
XML files.
• You can easily retrieve data from any object that
implements the IEnumerable<T> interface.

3. Areas of LINQ
• LINQ to Objects(query performed against the in-
memory data).
• LINQ to XML(XLINQ).
• LINQ to ADO.Net
• LINQ to SQL
• LINQ to DataSet
• LINQ to Entities(ORM solution).
