Hello guys!
Quick question. Would you like anymore videos on Big Data, Data Science or any other topics?
Please let me know. I'm focussed more on CSS tutorials right now.

Can you explain about mongo db in dbms pls

[@timbarnbou372]

Thank you. Wouldnt mind a little more in depth but this was perfect for a quick overview for someone that is new to this topic.

[@ConstantLearners_AI_ML_CS]

Thank you. Stay tuned for more.

[@amirassadi]

Thank you for your VERY clear and eloquent presentation. You have a VERY well-organized flow of conceptual logic, and clearly representative of depth of your knowledge. I have subscribed with the hope that you add to your videos, take your viewers to a journey of exploration of the recent advances in DB theory and implementation. Certainly it is a long journey when ordinary lecture series take on the task. I am certain you will invent a most efficient, yet rigorous road to this goal. My gratitude and admiration.

[@ConstantLearners_AI_ML_CS]

Thank you so much for your very kind words. Although they make me a little nervous on this journey of learning and sharing, but I will try my best to be able to give my best.💛

If I may ask,, is there anything like object oriented database model please explain

[@ConstantLearners_AI_ML_CS]

Yes there is OODM. But in this video I have only explained the basic database models. OODM is an advanced kind where data is stored in the form of objects. If you have learnt object oriented programming languages, it is easy to understand OODM also. In relational databases we could store only a single kind of data in tables. But in OODM we can store any form of data in the form of objects. And these objects are real world entities.

[@michaelphillips5844]

Are there only 4? I see some sites have object-oriented, flat data model etc.

[@ConstantLearners_AI_ML_CS]

Yes there are more, but the most basic ones are these. For example, Object-oriented databases were built to overcome the drawbacks of RDBMS and give databases more strength and structure.

[@randikemendis5860]

Good Explanation
P.S:- ERD relationship part I have got clear. in this example Doctor --> Duties --> Department "When it go like that his all operations related to that department will cover by one relationship. is it ok ?

[@ConstantLearners_AI_ML_CS]

Thank you so much. I am glad the video could help.
Yes you are right, the doctor's duties in that department will connect him to that department, because the doctor has duties in that particular department. So in the doctor's table and the department's table, some entries will be same like doctor's visiting hours, etc and thus establish a relationship between both. I hope I was clear.

What weaks are you referring to?
Actually these concepts are so vast in themselves, that I didn't want to add anything more. However, there is a recent video that I have uploaded on data models, I am sharing the link for that, I hope that it will help.
