ActiveX Data Objects (ADO)

ActiveX Data Objects (ADO)

ActiveX Data Objects (ADO) is a set of data access components provided by Microsoft that allows developers to access and manipulate data from a variety of sources in a uniform way. ADO is based on the ActiveX technology, which is a set of software components that can be used to build and customize applications.

ADO provides a number of components that can be used to connect to and work with data stored in a variety of formats, including databases, spreadsheets, and text files. It provides a set of interfaces that allow developers to execute queries, retrieve data, and update data stored in a data source.

One of the key benefits of ADO is that it provides a unified interface for working with data, regardless of the underlying data source. This means that developers can use the same code and techniques to work with data from different sources, such as a SQL Server database and an Excel spreadsheet.

ADO is widely used in a variety of applications, including web applications, desktop applications, and mobile apps. It is often used in conjunction with other technologies, such as the .NET Framework and Visual Basic, to build powerful and scalable data-driven applications.
