|
Answer» Store SCHEMA definition language (SSDL) is an XML-based language that describes the storage model of an Entity Framework application. In an Entity Framework application, storage model metadata is loaded from a .ssdl file (written in SSDL) into an instance of the System.Data.Metadata.Edm.StoreItemCollection and is accessible by USING methods in the System.Data.Metadata.Edm.MetadataWorkspace class. The Entity Framework uses storage model metadata to translate queries against the CONCEPTUAL model to store-specific COMMANDS.
