Common use cases

- Because of the vast number of methods Linq provides,…there are a multitude of strong use cases for it.…Perhaps the best reason to use Linq,…is to provide an easy way to perform…complex queries with different data sources.…Imagine a company that uses an SQL data base…to keep track of their products,…sales, customers and distributors.…They want to easily be able to create XML-based…daily reports based on this data.…They also receive monthly XML-based sales reports…from their distributors.…

Creating a program to help with that,…would require the ability to query…from different sources: SQL and XML,…which would require learning the unique syntax…to create the data.…As well, the company also receives reports…from their suppliers in a non-XML format.…The data can be imported into a program…but they need to create their own functions…to query this data.…With a large variety of materials and products,…from different suppliers and different ways to combine them,…the queries can become complex…and creating custom code can become difficult.…
