Have you ever wondered what the full form of ADO stands for? We will be taking a deep dive into this technology and explaining exactly what it is, how it works, and its advantages. Read on to find out more about this revolutionary software!
Full Form of ADO
The full form of ADO is ActiveX Data Objects. It is a Microsoft technology that provides access to data from various sources, including relational databases, non-relational databases, and file systems. ADO allows developers to write programs that can connect to different data sources and retrieve data from them. It also enables developers to update data in these data sources.
What is ActiveX Data Objects (ADO)?
ActiveX Data Objects (ADO) is a programming interface that provides access to data sources from Microsoft. It is designed to work with OLE DB providers and ODBC data sources. ADO allows developers to write programs that can access data from a variety of sources, including databases, spreadsheets, and text files. ADO is also capable of working with data in different formats, such as XML.
The Different Types of ADO Objects
There are four different types of ADO objects: Connection, Command, Recordset, and Stream.
Connection objects are used to connect to a data source. Command objects are used to execute SQL commands. Recordset objects are used to store data from a data source. Stream objects are used to read/write data to/from a data source.

The ADO Object Model
The ADO object model is a set of objects that you can use to access data from a variety of sources. The main objects in the model are the Connection, Command, Recordset, and Field objects.
- The Connection object represents a connection to a data source. You can use the Connection object to connect to a database, execute SQL commands, and retrieve data.
- The Command object represents an SQL command that you can execute against a data source. You can use the Command object to execute stored procedures, run queries, and return results sets from a database.
- The Recordset object represents a set of records from a data source. You can use the Recordset object to iterate through a result set, add new records to a database, edit existing records, and delete records from a database.
- The Field object represents a field in a Recordset object. You can use the Field object to retrieve information about a particular field in a record set (such as the name of the field, the data type of the field, and the value of the field).
Using ADO with Visual Basic
If you’re using Visual Basic, then you can take advantage of ActiveX Data Objects (ADO) to easily work with data sources like databases. ADO is a set of COM objects that provide a consistent interface for accessing data from a variety of sources. With ADO, you can connect to databases, issue queries, and update data.
To use ADO in your Visual Basic code, you first need to add a reference to the Microsoft ActiveX Data Objects Library. To do this, open your project in Visual Basic and go to the Tools menu. Select References and then check the box next to “Microsoft ActiveX Data Objects x.x Library”, where x.x is the version number of ADO that you’re using.
Once you have a reference to the ADO library, you can start using it in your code. The first thing you’ll need to do is create a Connection object that represents your connection to the data source. For example, if you’re connecting to a SQL Server database, you would create a Connection object like this:
Dim conn As New ADODB.Connection
conn.ConnectionString = “Provider=SQLOLEDB;Data Source=MySQLServer;Initial Catalog=myDatabase;User ID=myUsername;Password=myPassword;”
conn.Open

The following are some sample programs that show how to use ActiveX Data Objects (ADO) with various data sources.
- connect to Microsoft Access database using ADO
- connect to Microsoft SQL Server database using ADO
- connect to Oracle database using ADO
More Information on ActiveX Data Objects (ADO)
ActiveX Data Objects (ADO) is a set of Component Object Model (COM) objects that provides access to data sources. It is a part of the Microsoft Data Access Components (MDAC) stack. ADO allows you to use various programming languages to access data stored in databases.
ADO consists of four main objects: Connection, Command, Recordset, and Field. The Connection object represents a connection to a data source. The Command object represents an SQL statement or a stored procedure. The Recordset object represents a recordset generated by the Command object. The Field object represents a column in the Recordset object.
To use ADO in your application, you need to add references to the following COM components:
- Microsoft ActiveX Data Objects 2.1 Library
- Microsoft ActiveX Data Objects Recordset 2.1 Library
- OLE DB Provider for Microsoft Jet 4.0 (optional; required if you want to use Microsoft Access databases)

FAQs
Q. What are the benefits of using ADO Objects?
Ans. ADO objects offer a number of benefits, including performance and flexibility. When working with data in your applications, you can choose to use either static or dynamic cursors. Static cursors are faster than dynamic cursors but are less flexible; dynamic cursors are more flexible but may be slower.
Q. What is the difference between an ADO Recordset and an ADO Connection?
Ans. An ADO Recordset object represents a set of records from a database. An ADO Connection object represents a connection to a data source.
Q. What is the full form of ADO?
Ans. The full form of ADO is “ActiveX Data Objects“
Conclusion
I hope this article has provided you with all the information you need to know about the full form of ADO. If you are working with data in your project, then you may want to consider using ADO. ADO is a great way to work with data in your project because it is easy to use and it is very reliable. Plus, ADO is a great way to connect to databases so that you can retrieve data from them.
