      • Algorithms
      • Pattern/recognition
    • Program structures
      • Sequence
      • Selection

    • Variables
      • Data type
        • Casting
          • Assign a data type or reassign
            • E.g. count = str(count)
            • Count=int(count)
        • Interger, float/real,string,data
      • Identifier
        • Known by e.g. (name)
    • Functions
      • Call from main program, pass a parameter/argument
        • E.g. count(37) - identifier of function - parameter
    • Tracing a program
      • tracetable - write down values of the variables
    • Testing
      • final
      • Iterative
        • During development
    • SQL
      • Select* or frame, move/dob - from = tablename - where = something= a condition
    • Types of language - low level(assembly) or high level(pyton)
