My answer won't help you in the immediate question but it is an answer you need to know anyway for future reference.
ANY database project (actually ANY project that MAKES something that someone else will use) should have some kind of design document in which you analyze the problem, lay out a plan of attack, list clear project milestones, and specify abilities that would let you define readiness. If you didn't define readiness criteria up front, you cannot answer the question with any certainty and WE can NEVER define readiness for you. Readiness for user consumption means that it will do what it was supposed to do X% of the time. (What was it supposed to do again? Oh, we didn't write that down. I guess we don't know if we are ready or not.)
This isn't meant to be a rude response, though. It is more a response to drive home the point that we can never answer that question. Only YOU can decide (or could have decided) whether project ABC is functionally ready for the real world. We know principles. YOU know your project. But readiness is not a principle. It is a quantified list of abilities to respond to expected situations, anticipated inputs, hypothetical report requests, etc. You make a list of what you wanted to be able to do, then check off items on the list. Mark the critical items specially. Add a couple of more like "Won't crash out from underneath a user just after a two-hour input session without saving data." and "Won't give wrong answers to legit questions."
I'll answer a related question that you didn't ask but should have, because it is the only generic answer anyone can give you. When is a given project (Database, program, piece of engineering, building, ...) complete? Answer: On the day that no one is still using it and no one will in the future use it. Until then, you are never done. You might be in a slow spot but you are never done with a "live" program.
