ADO consists of several top-level objects:

*Connection (Object - represents the connection to the database).

*Recordset (Object - represents a set of database records).

*Command (Object - represents a SQL command).

*Record (Object - represents a set of data, typically from a source other than a database).

*Stream (Object - represents a stream of data, as from a text file or web page).

*Error (Object - stores errors).

*Field (Object represents a database field).

*Parameter (Objrct - represents a SQL parameter).

*Property (Object - stores information about objects).

The ADO components are usually used in conjunction with a high-level language such as [[VBScript]] in an [[Active Server Pages|ASP]] environment or [[Visual Basic]]. However, languages such as [[Borland Delphi|Delphi]] and [[C++ Builder]], development environments from Microsoft rival [[Borland|Borland Software Corporation]], also allow the use of ADO to access various databases.
