I am from the Business Intelligence, Data Analytics background. So mostly Tableau, reporting tools and databases. But there are only 77 database related problemsets compared to few 100's or 1000's for other areas? Also didn't find any information related to Database in sections for contests, interview, compensation and other sections. I can go for premium but looks like I will be disappointed with little to no information.

Am I looking at the wrong places? Am I missing something? Would love some help.

Thank you!
