Universal Data Access (UDA)
Universal Data Access (UDA) is Microsoft's model or framework for a single uniform application program interface to different software makers' databases, both relational and nonrelational. UDA is the database access part of Microsoft's Component Object Model (COM), an overall framework for creating and distributing object-oriented programming programs in a network. UDA consists mainly of the high-level interface, ActiveX Data Objects (ADO) and the lower-level services called OLE DB. IBM, Oracle, and other companies have provided database bridges that interface with OLE DB.
