ADO stands for ActiveX Data Objects. It is a data access technology that allows developers to access and manipulate data from a variety of sources, including databases, spreadsheets, and text files, in a uniform manner.
ADO is part of Microsoft’s suite of data access technologies, which includes DAO (Data Access Objects), RDO (Remote Data Objects), and OLEDB (Object Linking and Embedding, Database). ADO was introduced in 1998 and was designed to replace the previous data access technologies.
One of the key features of ADO is its ability to work with data stored in a variety of formats and to communicate with different data sources using a common set of methods and properties. This allows developers to access data stored in Microsoft Access, Microsoft SQL Server, and other databases without having to write different code for each data source.
ADO also provides a flexible and efficient way to manipulate data. For example, it provides a way to filter data, sort data, and group data. It also provides methods for inserting, updating, and deleting data.
ADO is a component-based technology, meaning that developers can use the components in their applications. These components can be reused in other applications, making it easier for developers to create new applications that access data.
In conclusion, ADO is a powerful data access technology that provides developers with a way to access and manipulate data from a variety of sources. Its component-based architecture, ability to work with different data sources, and efficient data manipulation capabilities make it an important tool for developing data-driven applications.
