[TYPO] Databases - Relational Algebra and Calculus

Please be specific as possible and add a link to the relevant file/lines.

Hi, I just wanted to point out there is a typo in the OMSCS database class notes. It is located in the Relational Calculus and Algebra section and the sub-section is Relations are Sets (https://www.omscs-notes.com/databases/relational-algebra-and-calculus/#relations-are-sets). I believe there is a missing closing left paratheses next to the relation name.

So instead of looking like this:

πSex((σHomeTown='Atlanta'RegularUser))

It should be like this:

πSex((σHomeTown='Atlanta'(RegularUser))

Also for the query above it as well, I think the relation name should be within the paratheses of the selection operation. I'm not sure how important this is and it may not matter anyways, but this the format the professor uses so I thought maybe it would be good to keep everything consistent.

By the way, thank you so much for making these notes I very much appreciate the work you put into them!!!

Best Regards,
Michael
