bhaiya one suggestion , when you start a topic please try to finish it there only. Like for example you started attributes and then there you didn't discussed the types there. then you started Relationship there also types were discussed later. Main problem in this is when i'm making notes then starting one topic has to be finished there so that notes end up sequentially . rest everything is fabulous .
