Dogs ’n’ data

What & why

We’re going to explore creating data structures that are common to programming—by describing dogs.

Often information needs to be structured with a limited set of data types.

Data structuring is critical to understanding configuration and program information storage.

Data structures

  • string — just some text
  • number — just a number
  • boolean — true or false
  • array — a collection, like <ol>
  • object — a named collection, like <dl>

Simple example

name: Paddington
size: Small
weight: 5
colours:
  - Brown
  - Black
  - White

Set up

  1. Form into pairs
  2. Get assigned a dog
  3. Get a pencil & a piece of paper
  4. Describe the dog’s attributes using data structures
    In a way that would work for every dog
  5. Present the structure so we can build a specification
