@SelvarajC16771071 Datapage is a temp database where instead of fetching data everytime from database, Dpage will run and store the data in the clipboard, so that no need of hitting the database everytime. This improves the performance. Scope refers to the duration for refreshing the data. 

If Thread is set - whenever the dpage is called/referred , the dpage runs and it will bring the current data(example:stock market)

If Requestor is set - Operator logs in and refer the dpage for first time , dpage will run and loads the data in clipboard. until or unless operator logs off or flush the dpage manually . the data remains same (example:fetching gold price) which changes twice a day .

If Node is set - let's say the data changes once in 24 hours. Operator logs in and refer the dpage for first time , dpage will run and loads the data in clipboard across the application. until or unless next operator logs in  the other day  the data remains same (example:date). Hope this helps.

Depends on the context , you have to set the scope. 

Thanks
