What does ADO mean in SOFTWARE
ADO stands for ActiveX Data Object, and it is a significantly useful technology used in computing. ADO is used as an interface by which software applications can access different data sources on a Windows system. As such, it can be essential to the operation of many programs, allowing computers to effectively store and utilize information as needed.
ADO meaning in Software in Computing

Essential Questions and Answers on ActiveX Data Object in "COMPUTING»SOFTWARE"
What is ADO?
ADO stands for ActiveX Data Objects and it is a set of components that provides access to data sources. It is used to connect applications to databases in order to query, retrieve, and update data. ADO can be used to interface with databases such as MS Access, SQL Server, Oracle, DB2, Sybase, FoxPro etc.
What types of data sources are supported by ADO?
ADO supports both OLE DB and ODBC providers for accessing numerous types of data sources. This includes relational databases such as SQL Server, Oracle and Informix; file-based databases such as MS Access, dBase and FoxPro; HTML documents; text files; spreadsheet applications like Excel; mail systems like Outlook; web services; and other non-database information sources.
How do I use ADO in my application?
To use the features of ADO within an application, you must create an ActiveX Data Object (ADO) object within your program. This can be done in several ways including using the CREATEOBJECT() keyword in Visual Basic (VB), or by creating a reference to "Microsoft ActiveX Data Objects" through VB's Tools menu. Once created this object can then be used to manipulate various data objects.
What objects does ADO provide?
The main objects provided by ADO are the Connection Object which controls the connection between your application and a specific data source; Command Object which allows execution of queries against a specified data source through an open connection; Recordset Object which stores the records from executing a query against a specified data source; Error Object which provides details about potential errors encountered during operations with an open connection or command object; Field Object which stores field attributes associated with each recordset field returned from an executed query against a specified data source.
How do I close connections once I'm done working with them using ADO?
Connections opened using an ActiveX Data Object (ADO) must always be closed properly when finished using them. This can be accomplished by calling the Close method on the Connection object instance created earlier when opening the connection. This will ensure that resources associated with that particular connection are released properly.
How do I navigate through recordsets using ADO in VBScript?
You can use the MoveFirst(), MoveNext(), MovePrevious() or MoveLast() methods available on the Recordset object instance created earlier when creating your connection to navigate through your recordset in VBScript code. These methods will allow you traverse through all records returned from executing your query against a specified datasource.
Is there any way I can limit how many records are returned from my query with ADO?
Yes you have two options available if you wish to limit returning results from executing queries against datasources using ActiveX Data Objects (ADO). You can either specify the desired page size before execution or you could also issue specific TOP statements within your SQL select statement when constructing your queries.
Can I execute stored procedures with ADP?
Yes this is possible by calling the Command Execute method on an open Command object instance and passing along all required parameters as necessary for direct execution.
Final Words:
Ultimately, ADO stands for ActiveX Data Object - an essential component used in developing programs on Windows systems which helps facilitate efficient communication with back-end databases. As such, it plays an important role in ensuring that applications are able to quickly and correctly access the information they need from pre-existing data stores without having to manually code numerous commands or queries for each piece. By leveraging this technology judiciously during development cycles, programmers are able to reduce their time spent coding while improving overall functionality when their projects reach completion stages.
