What are the ADO.NET objectives?
ADO.NET provides consistent access to data sources such as SQL Server and XML, and to data sources exposed through OLE DB and ODBC. Data-sharing consumer applications can use ADO.NET to connect to these data sources and retrieve, handle, and update the data that they contain.
Where are datasets stored?
Disks or tape are most frequently used for storing data sets on a long-term basis. Disk drives are known as direct access storage devices (DASDs) because, although some data sets on them might be stored sequentially, these devices can handle direct access.
What is the full form of ADO?
The Full Form of ADO is Active Data Object on a computer. Active Data Object Microsoft introduced ADO in October 1996 for programming developers. ADO is a set of Component Object Model objects for accessing data sources. it helps programmers to access the middleware layer between programming languages and OLE DB.

What is the role of ADO.NET in .NET architecture?
ADO.NET provides a bridge between the front end controls and the back end database. The ADO.NET objects encapsulate all the data access operations and the controls interact with these objects to display data, thus hiding the details of movement of data.
How many types of datasets are there?
There are two types of categorical data sets: dichotomous and polytomous. In a dichotomous data set, each variable can only have one of two values. For example, a data set containing answers to true and false questions is dichotomous because it only supplies one result or the other.

What is ADO and RDO?
ADO and RDO allow you to use Visual Basic or other COM-enable programming language to connect to the database directly (circumventing the objects) through RODBA with the restrictions that RODBA provides. The ADO and the RDO are objects that allow a application to connect to a database and "talk" to it through SQL.
