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.

All applications that communicate with an instance of SQL Server do so by sending Transact-SQL statements to the server, regardless of the user interface of the application. The following is a list of the kinds of applications that can generate Transact-SQL: * General office productivity applications.* Applications that use a graphical user interface (GUI) to let users select the tables and columns from which they want to see data.* Applications that use general language sentences to determine what data a user wants to see.* Line of business applications that store their data in SQL Server databases. These applications can include both applications written by vendors and applications written in-house.* Transact-SQL scripts that are run by using utilities such as sqlcmd.* Applications created by using development systems such as Microsoft Visual C++, Microsoft Visual Basic, or Microsoft Visual J++ that use database APIs such as ADO, OLE DB, and ODBC.* Web pages that extract data from SQL Server databases.* Distributed database systems from which data from SQL Server is replicated to various databases, or distributed queries are executed.* Data warehouses in which data is extracted from online transaction processing (OLTP) systems and summarized for decision-support analysis. Also in short,T-SQL (Transact-SQL) is a set of programming extensions from Sybase and Microsoft that add several features to the Structured Query Language (SQL) including transaction control, exception and error handling, row processing, and declared variables.
