00:00 So far, we've been kind of poking at MongoDB, 00:03 playing around with some of maybe existing data 00:05 or creating simple little databases with one or two records in it. 00:09 We're kind of done with that, we're ready to move on 00:11 to be building the main application that we're going to build for this course. 00:15 So we're going to take this concept of a car dealership 00:18 that does service for autos, sells cars, does service like engine repair, 00:23 fixes flat tires and so on, for a Ferrari dealership, 00:26 and that's going to be our demo for the rest of this course. 00:29 On this first go round, we're going to start out 00:32 with an empty database or a non-existent database, 00:34 we're going to model it in MongoDB with MongoEngine 00:38 and then we're going to run that code and create a few simple cars, 00:41 a couple Ferraries, maybe associate the cars with some owners, 00:45 do some service on the cars, somebody over rev the engine 00:48 and has got to get a new engine, or got a flat tire, 00:51 things like that; we'll see how it all works. 00:53 Later, when we get to the high performance section, 00:55 we're going to instead of start with an empty database 00:57 start with one with like a quarter million cars and tons and tons of service records 01:02 and they will start asking really interesting questions 01:05 and really focus on the performance side of things. 01:08 So we're going to use this for the rest of our time 01:10 and I have been really waiting till we got to the MongoEngine section 01:13 to create what I would think of as a somewhat realistic complex demo 01:17 because with PyMongo it's fine, but you'll see the real power of modeling this 01:21 in a full featured realistic production style way 01:25 once we get to MongoEngine things like indexes and uniqueness, 01:29 and constraints and types and lots of good stuff. 01:32 So I hope you're ready to learn MongoEngine, 01:34 and put it to work building this cool Ferrari dealership.
