ActiveX Data Objects (ADO) was created by Microsoft to provide a standardized Object Model for connecting to a wide variety of external data sources, as part of the Universal Data Access (UDA) plan. UDA refers to a plan in which there is a single, standardized object that can be implemented to retrieve data from any type of data source. Specifically, the "Object Linking and Embedding Databases" (OLE DB) is the UDA interface that enables providers to implement data access to their data source. ADO is the API that sits on top of OLE DB, providing the code functionality. Essentially, ADO is a code library that allows developers to work with data from all different types of data sources.
