JSON API Data Knowledge

1. Data Interface

   • User Interface
     • Tables
       • Row
         • All characters page: value
         • Character page: name, height, age, gender, eye color
       • Column
         • Character page: attribute and value
         • All characters page: name, height, age, gender
       • Used to display organised data for users
     • Cells
       • Sample Data
         • "name": "Luke Skywalker", "height" : "172cm"_______, "mass": "77kg"__________ "hair color": "blonde"____
         • Data structure
         • Data type
     • Headings
       • Define each row/column/section of data
       • Character page - 'character name'
       • All characters page - "All Star Wars Characters"
     • HTML
       • Table/webpage Structuring and Appearance on webpage

         • Provides aesthetic appeal for increased user engagement
         • Allows to highlight more important information
         • Examples: Bolded, colorful text, borders, margin, padding

2. Data Structures

   • JSON
     • API
       • Arrays
         • List of values that can hold multiple data types (including strings and integers)
       • Values
         • Data that can be displayed
           • Can be string (words, text) or integer
             • e.g. "Luke Skywalker", 77
               • Key-value pair: "key": value e.g. "name": "Luke Skywalker", "age" : 77
                 • e.g. "name", "age
       • Keys
         • Unique identifier for value within object
           • e.g. "name", "age"

3. Data Specifications

   • JSON
     • Validation
       • Checks data type is correct and suited
       • Checks syntax and structure
       • Ensures constraints are adhered to
       • HTML
         • Formatting must be correct
     • Data Types
       • Objects
         • Key Value Pair
           • e.g. "eye_color": "blue"
             • Max data length: 255
       • String
         • Textual elements like words or characters
           • e.g. "Luke Skywalker"
           • Max data length: 255
       • Boolean
         • Used to determine if a condition is met or not - either "true" or "false"
           • e.g. "is_jedi": true
       • Array
         • List of values - different data types
           • e.g. "movies": ["Return of the Jedi", "Return of the Ewok"]
           • e.g. "co-characters": ["Yoda", "Princess Leia", "Darth Vader"]
           • Max data length: 255
       • Null
         • Value property showing empty cell or element
       • Integer
         • Numbers or digits
           • e.g. "age": "77"
           • Max data length: 255
     • Constraints
       • Data must be an array
       • Value constraints
       • Data length
