System Design
• Coding Languages

display invalid input messages
▫ As well as give an example of
correct format
• Platform Support
▫ Windows only
▫ i.e. (!MAC && !LINUX)
• Modifiability
▫ Modules are opened ended
▫ Design your own solar system or
build another one
 Default is our own Solar System
• Constraints
▫ Take up minimum amount of
memory
 Less than 512 MB of RAM
▫ Low CPU usage
 Can’t interfere with user task
 Less than 5% CPU usage
• All constraints are going to be based
off the recommended hardware.

Part B.1
• Simplification (abstraction)
▫ I analyzed the composition of our solar system and pulled the most relevant objects
that occupy it. 8 Planets, 2 Asteroid Belts, and a single star/sun. There are comets
and asteroids that move about through our solar system. The planets have a
gravitational pull on objects, an orbit ring around the sun, and a rotate with some
tilt on their axis. All of these events take place over time.
• Refinement (what details you decided to add)
▫ I broke down aspects of the solar system further and made them into modules that
could be generally. Instead of making Saturn, I make a planet object that has the
attributes of Saturn. This would promotes modifiability and add planets to our solar
system if needed. I wanted to maintain this trend for all my modules. For Example,
the sun is a star object that has the same, mass, volume, density, and is a main
sequence star. From breaking down my objects into these modules, I got the idea of
making this Solar System simulator into an interactive background of your very
own solar system that you can create. I added features that would make this
system more interesting to play around with. Time manipulation and the ability to
create any object and placing it into your solar system on the fly. Special Effects and
Music were aspects to make it flashy and relaxing. These extra features will allow
the user have an experience with this product.
Part B.2
• Discuss the criteria you used to determine that your model was “good
enough” to hand in
▫ My product is a component based design that satisfies all the
requirements of what our solar system has to offer. I added more
requirements to make my solar system product more unique and
hopefully more to offer than just a simple educational program. Each
component/module has attributes or sub components that accomplish
its task. The modules have a well defined layout of how they relate and
interact with each other. It needs to be refined one more level to see
code solutions ,but the overall system architecture is complete. I think
that my design is balanced in both product and engineer design.
Default Solar System & Questions
• Create your own!
• See what happens when you
spawn a star in a random
location
• Launch comets at planets
• It’s your Solar System!
