It would certainly simplify the equation to get rid of one side or the other.Yet relational databases provide critical infrastructure for long-term storage and query processing, and modern programming languages are indispensable for agile development and rich computation.Until now, it has been the job of the application developer to resolve this mismatch in each application separately.The best solutions so far have been elaborate database abstraction layers that ferry the information between the applications domain-specific object models and the tabular representation of the database, reshaping and reformatting the data each way.(119 printed pages) Introduction A Quick Tour Creating Entity Classes The Data Context Defining Relationships Querying Across Relationships Modifying and Saving Entities Queries In-Depth Query Execution Object Identity Relationships Joins Projections Compiled Queries SQL Translation The Entity Lifecycle Tracking Changes Submitting Changes Simultaneous Changes Transactions Stored Procedures Entity Classes In-Depth Using Attributes Graph Consistency Change Notifications Inheritance Advanced Topics Creating Databases Interoperating with ADO.

The following chapters provide an overview of how LINQ to SQL can be used to perform common database-related tasks.How information is represented—the data model—is quite different between the two.Modern programming languages define information in the form of objects. Objects have unique identity as each instance is physically different from another. Objects have references that identify and link instances together.Yet by obscuring the true data source, these solutions end up throwing away the most compelling feature of relational databases; the ability for the data to be queried.LINQ to SQL, a component of Visual Studio Code Name "Orcas", provides a run-time infrastructure for managing relational data as objects without losing the ability to query.
