Oh boy. Gotta love having a team member (For a School project) be in charge of the Database functionality/design, who has almost no communication skills and basically no clue about how to store data in a data base.
Im talking dates stored as varchar(5), column sizes being way way to small, overall table design being rather terrible, no primary/foreign keys, pretty much... Actually no, everything was being stored as a varchar.
Not only that, but there was a hell lot of data that needed to be stored that wasn't even accounted for in the DB design. He made some code that could be used by our team members for queries, creating tables, inserting data (etc), almost 2,000 lines of it.... And basically nothing was fucking documented at all. I'm talking comments like "Insert data into cities table" and nothing else. More complicated functions had as much, or less documentation. Complete mess.
