TXDataBaseModel Class

Base class of the XData model, holding its schemas and the methods to look up its items.

Remarks

Methods that receive a qualified name accept the local name prefixed by the namespace or alias of the schema, as in XData.Default.Customer. The prefix can be omitted for items of a schema with no alias, which is the case of the model built from the Aurelius mapping.
