This document discusses key concepts in software development including data types like boolean, integer, real, and string. It also covers programming constructs such as sequence, selection, and iteration. Finally, it outlines the typical documentation for a software project like requirements specification, test plans, code listings, and completed test logs.

1. Software Development

2. Data Types
• Boolean – expresses truth values (true or false)
• Integer – whole numbers, not fractional, can be positive, negative or
zero
• Real – stores floating point numbers i.e. 1.54 and 1.77. These include
numbers such as 1/3 and Pi
• String – stores alphanumeric combinations and text – typically text
than can contain numbers and spaces

3. Programming Constructs
• Sequence – list of instructions to be carried out one after the other.
Each instruction can be carried out once
• Selection – two or more sets of alternative instructions with one path
being chosen accordingly to the value of a condition
• Iteration – a set of instructions that could be repeated zero or more
times

4. Programming Specification/Documentation
• Requirements Specification – requirements the app must meet
• Detailed Design – proposed design of the final app
• Test Plan – table explaining expected results/outcomes
• Code and Layout Listings – prints of Java/.xml files etc.
• Test Strategy – plan of testing the app
• Completed Test Log – recorded events of testing the app
• APK File – the app file itself

5. Software Development Terms
• Constant – a value that cannot be altered by the program during
normal execution
• Debugging – locating and correcting code errors in a program. Part of
the software testing process and development lifecycle
• Pseudocode – Detailed yet readable description of what a
program/algorithm must do, expressed in a natural language rather
than programming languages
• Variable – a value that can change depending on conditions or
information passed to the program

6. Software Development Terms
• Concatenation – the operation of joining two strings together
• Functional/Non-Functional Requirements – what the system should
do, and non-functional describes how the system should work
• Application Programming Interface – toolset for programming GUI
• Modular Programming – allows the program code to be written by
more than one programmer
