2.2 (Programming)

1. Itteration

   • Loops - run through similar items of data

2. Counter

   • FOR counter 1-5 Output counter

3. Sequencing

   • It allows programs to solve tasks through a number of steps
   • Allows computers to think

4. Strings

   • It inputs a certain length of a certain word
     • stringname.length stringname.upper stringname.lower

5. Data

   • Data Peristance is storing data to be used later on
     • Such as text files

6. Abstraction

   • Describing the problem in more detail and making it easier to solve

7. Algorithmic Thinking

   • Pseudo Code - Statements written for each step
   • Flow Chart - A set of shapes to make a diagram for each step

8. Pattern Recognition

   • Any repeated code in solving the task, the pattern will simplify the steps

9. SQL

   • Standard Query Language, it is a language that is used with databases
     • Stored in MySQL, Oracle, SQLite instead of text files
   • SELECT FROM Scores WHERE Scores > 10
     • It this it where to get the data from and the criteria stats

10. Arrays

    • An array can store multiple pieces of data
    • Usually have fixed sizes and occupy a static (set) amount of memory

11. Sub Programs

    • Used to save time and simplify code by avoiding repetition of code
      • Main types are procedures and functions

12. Records

    • Stored in data
      • Stored in RAM
      • Useful for small volumes of data
    • Stored in Text Files
      • Stored in the Hard Disk
      • Store data while a program isn't running
      • Useful for small volumes of data
      • Requires linear search, which is slow
