Bad data breeds like Tribbles. Coddle even one bit of it, and your entire database will fill up with junk. And it's got so many causes! Weird user input. Data races under load. Changing business needs. We can't fully prevent data corruption, so how can we recover from it? In this talk, you'll learn how to fix bad data at every level of your system. You'll learn UX techniques for incremental, mistake-reducing input. You'll get a rubric for validation design that accomodates new features. And you'll learn auditing techniques to catch bad data early, before your database fills up with evil Tribbles.
