ActiveX Data Objects (ADO)-

ActiveX Data Objects (ADO) is a data access interface developed by Microsoft. It allows applications to connect to, retrieve, manipulate, and update data from OLE DB–compliant data sources such as SQL Server, Access, Excel, or other databases.

Here’s a breakdown:

• ActiveX Data Objects (ADO): A high-level programming interface for data access.
• OLE DB–compliant sources: A standard for accessing data from a variety of sources (not just relational databases).
• Uses: Used in languages like VBScript, Visual Basic, and early .NET applications.
• Key capabilities:
  • Establish database connections
  • Execute queries and stored procedures
  • Navigate recordsets (results)
  • Update and manage data

ADO is commonly used in legacy Windows applications, especially in scenarios involving COM (Component Object Model) technologies. It has since been largely replaced by ADO.NET in modern .NET development.
