I investigated further on the downloads and views field in the app store and here is what I found:
1) There is no such field as views in the database. But, it would be a nice to have feature for the developers to know how many times their app has been viewed.
2) There is no code corresponding to increment in the number of downloads in the codebase. We can remove the database field which corresponds to the number of downloads as we directly have an install option on the app store. Or we could use that field to show number of installations for the respective apps in the appstore so that the existing database field would be used instead of introducing a new one.
