SIR Suppose i want to update field Date of birth of employee in PA0002 than using abap perspective (Application layer) i can do it and directly in database also i can do it and where ever i do change will happen in database And also same change will happen in application layer if i do dirrctly in hana perspective
So if no matter what where ever we do change reflects in both data base and same can be seen through application so what particularly is the use of using Hana perspective instead of abap
My guess, each perspective has its own properties and same functionality (ex your update option) can be done in both perspectives. Simple ABAP example, SE38 and SE80 are two different window but program can be done in both transaction. I am not fully gone through all the properties of the each perspectives. So this might give some insight of your question.
