The sybase tag is ambiguous, as Sybase has two quite distinct database products: sybase-ase and sqlanywhere. Many questions are not tagged correctly, because both Sybase products are literally just called "Sybase" by end users. But then it's kind of hard to determine the correct product in questions like this one here, which in turn leads to wrong answers and unnecessary discussions:
But in principle, tagging these questions simply with sybase is about as wrong as not caring whether you're asking a sql-server or an ms-access question and just blindly tagging it as microsoft... Or you might not care about if something is about ios or osx and just tag it as apple
How could this be improved? Should there be some warning rules attached to certain tags, e.g. when you tag your question with sybase, then you should also chose one of sybase-ase and sqlanywhere? Or should the sybase tag be completely removed and merged into the any of the other two?
