XML is becoming the defacto method for transferring data between applications and systems. The main advantages to creating a data backup or extract using XML are 1) because the data fiends are enclosed in tags, it is self-documenting; 2) data validation rules can be included with the files and 3) there is no export/import issues between applications.

Why do you use Linq over SQL Statements?
The extensibility of the query architecture is used in the LINQ project itself to provide implementations that work over both XML and SQL data. The query operators over XML (LINQ to XML) use an efficient, easy-to-use, in-memory XML facility to provide XPath/XQuery functionality in the host programming language. The query operators over relational data (LINQ to SQL) build on the integration of SQL-based schema definitions into the common language runtime (CLR) type system. This integration provides strong typing over relational data while retaining the expressive power of the relational model and the performance of query evaluation directly in the underlying store.
What is the difference between XML and SQL data storage?
In XML data storage, the data is stored in a file which represents an XML Schema of the data. To read the data, you have to pull and open the entire file in memory and use technics like xpath to get the data element you want. In SQL data storage, the data is stored in a database ( usually relational database). To read the data, you simple sent an SQL query to the database. The database management engine analysis the query and get the required data elements you ask for in your query which is finally sent to you as a reply.
