What is a DBML file?

XML file created by Microsoft's Object Relational (OR) Designer, which is included with Visual Studio and other Microsoft database software development tools; contains "LINQ to SQL" (Language-Integrated Query to Structured Query Language) entity classes that map to objects within a database.

More Information

DBML files are used by the Visual Studio Code Generator to auto-generate Visual Basic, C#, or XML source code files. This allows developers to manipulate database records directly as native classes within the application.

NOTE: DBML files are stored in an XML format and must conform to the published DBML .XSD schema.
