  3. 3App Dev Lifecycle (IDDS) :o Inception – Idea is formed, Work is planned
    o Design – A solution is proposed
    o Development – Coding work is performed, Graphics are created
    o Stabilization – Testing, Deployment and Maintenance
  4. 4IPO:- Input – Information provided to the program from outside of the program, often gathered from the user
    - Output – Information produced by the program for use outside of the program.
    - Processing – Computer programs perform some sort of calculation faster than humans
    - Coding – Coding is the process of converting an algorithm into computer code
  5. 5AppInventor Break Down:- Event Driven programming – Appinventor
    - A button clicked is an event
    - Components
    - Groups of blocks
    - 3 Key Elements (IPO)
    - Algorithms – Ordered sequence
  6. 6Appinventor: Types of blocks:o Event Blocks
    o Actions Blocks
    o Get-Value blocks

  7. 7App Inventor Code:- Conditional code
    - OR, AND, NOT
    - IF statements
    - Nested expressions
    - Relations between numbers
    - IF – THEN – ELSE
    - Variables allow us to store data to remember
    - NOT will give the opposite of answer
    - OR – One of which needs to return true
    - AND – Both need to return true
  8. 8App Inventor Lists:- Lists
    - Layout of components
    - Work out values of lists
    - Add items to list
    - Insert list item – Pushes other items down
    - Add items – Adds to the end of the list
    - Index is where in the list
    - Index length of list gets the final item in the list
    - Parallel Lists – Multiple lists with index relating to each other
    - Repetition
    - Iteration – each time a repetition is called
    - While-do – If true will perform command
    - For-each – Number variable says how many times it will repeat
    - Procedure – Group of our own code we can call upon later – Inputx on the cog for information provided can have unlimited variables
    - If a notch on the left of it means it has a return value
    - If only a dent at the bottom means no return value
    - Notch on the right means input value
    - Close screen – returns us to the previous screen
    - Result is the previous screen sent value
    - To select from a lists of lists, nest select list item on select list item with right index
  9. 9Databases:- TinyDB
    - A set of data about some single entity is called a record
    - Predetermined fields
    - When we have a collection of records, which all have the same consistent structure, then we have a database
    - TinyWebDB – A cloud based database
    - Files allow us to store files on the android device
    - List of Lists – 1 way of storing a database system
    - Persisting data means its able to remain after the app has closes
