Computational thinking

• OOP
  • Abstraction
    • Thinking of only the necessary parts of a problem, allowing a problem to solved more efficiently in terms of time and resources.
      • This can mean to only look at a specific function that the problem is associated with, instead of the entire program.
  • Polymorphism
    • To ensure a method will take all types of data we want it to. For example a shape method would have to accept all kinds of shapes.
  • Inheritance
    • A general class or similar is used in multiple parts of a program that has a set of functions inside.
    • An example of this is an to have a worker class, that includes functions such as work hours etc. A manager class would have all the functions a worker would, plus more
  • Encapsulation
    • To make functions within a class private, preventing outside functions from making changes to private attributes.
    • This prevents accidental changes from being made, which allows a program to still function properly
• OOP 2
  • BackTracking
    • Going back to the most recent working point of a program to save time and resources
  • Data Mining
    • Searching through large amounts of data to find relationships
  • Performance Modelling
    • Used to test how specific parts of a program may function. Testing Specific modules instead of an entire program.
    • Saves on time, resources and costs. Often the model needs to be very accurate to life represent a true to life result
  • Pipelining
    • Separating a program into sections where some problems can be processed in parallel to other problems.
  • Visualization
    • Using graphs and other visualization methods to find patterns and solve problems.
• Reusability
  • Reduces the cost involved in creating a new program.
  • Increases dependency on old code.
  • Collaboration is a great way to utilize reusability as many people can search for opportunities to reuse old code.
• Caching
  • Storing webpage data to decrease load time of a frequently visited page.
  • An old version of a website may be fetched from cache.
  • If an attempt to fetch a webpages cache and it isn't present, performance is lowered.
