Axe World

Your happy hour is boring. What better way to spend time with your coworkers then throwing axes?

We've got a bustling business where small groups book appointments then come to us to throw axes at the wall. But managing the paperwork is becoming a huge pain. Please help us with your database skills!!

I0: Getting Going

I think we should have a database called axeworld just like our business.

Top-Down & Bottom-Up

As we think about process there are two general ways to solve a software problem: top-down and bottom-up.

Top-Down

Top-down development tries to first define how the user or consumer will utilize the system. To do it well you ask questions about the interactions like:

• What kind of interface will the system have? (ex: web, mobile, hardware, etc)
