Question

I am working on a problem where I am trying to figure out the best way to design the Db tables for this. Lets say I have multiple books and each book has variable number of pages in it…I need to track page views for every book

e.g. Book 1 = 10 pages , Book 2 = 20 pages, Book 3 and 100 pages and so on
As the user views each page in a book, I need to log that information.

The motive is to come up with some aggregation numbers on the %views of each book. I should be able to say e.g. “70% people read Book 1 upto Page 7 and then drop off”

I envision it as

book 1 page 1 1000 views
book 1 page 2 950 views
book 1 page 3 800 views
.....
...
book 1 page 10 50 views

and with this I can generate a drilldown report of sorts

however, with variable page numbers in each book, what is the best way to store this information?

any help would be much appreciated

Answer 1

You will need to add an extra table:

PagesViews:

• BookId.
• UserId.
• PageNumber.
• ViewDate.
• …

With a composite primary key(BookId, UserId, PageNumber).
