A data provider is used for connecting to a database, executing commands and retrieving data, storing it in a dataset, reading the retrieved data and updating the database. Net consists of the following four objects: Data Adapter This is integral to the working of ADO.
This functionality should be implemented manually in the Save Workbook method and based on the requirements the developer should choose the most suitable approach to check which cells are modified.
