Universal Data Access (UDA) middleware defines a category of software that provides transparent access to data sources (such as databases) from Desktop Productivity Tools, Application Development Environments, and Web & Internet Points of Presence.
These drives come in two flavors:
- Single-Tier Drivers conform to the common perception of what an ADO.NET provider is (A single component installed on the desktop or workstation machine only. Once installed, it provides connectivity to local or remote databases.) Supported databases: SQL Server, Sybase, ODBC.
- Multi-Tier Drivers comprise client and server components, being equipped with an in-built database-independent networking layer and a session rules-book. These drivers are network-ready out of the box, and capable of dynamically discovering matching server components anywhere in a LAN/subnet using the Rendezvous service-discovery protocol. These drivers are described as "Multi-Tier" due to the fact that they include interface implementations at both the client and the server levels. Supported databases: Oracle, DB2, Progress, Informix, Ingres, MySQL.
