Study Notes

Technology in Action - Chapter 10

  • Chapter 10 is titled "Behind the Scenes: Software Programming"
  • This chapter is part of a textbook titled "Technology in Action"
  • The textbook is in its 16th Global Edition

Understanding Programming

  • Some tasks are complex and require creative thought and human touch
  • Other tasks are repetitive or involve electronic information, making them suitable for automation via programming
  • These tasks follow a series of clear steps

The Importance of Programming

  • Careers in programming offer plentiful jobs, strong salaries, and often easy telecommuting arrangements
  • Programming is necessary when no existing software is available to perform a specific task
  • Macros can accomplish complex sequences of steps with a single command

Life Cycle of an Information System

  • An information system is a collection of parts working together to achieve a common goal (e.g., a body is a system)
  • An information system includes data, people, procedures, hardware, and software
  • It helps in planning and decision-making
  • Systems such as online purchasing systems for companies such as Amazon and Netflix rely on information systems

System Development Life Cycle (SDLC)

  • The SDLC is a six-step model to develop information systems
  • Steps include problem/opportunity identification, analysis (developing specifications), design (using data flow), development, testing and installation, and maintenance/evaluation
  • Corporations form a development committee, analysts explore the problem, define requirements, and suggest a plan of action
  • Flowcharts and data flow diagrams support programming
  • Program performance is monitored to ensure it meets end-user needs

Life Cycle of a Program

  • Programming translates a task into commands for a computer to execute
  • Program Development Life Cycle (PDLC) outlines the stages from development to deployment
  • Problem statements clearly describe tasks
  • Data is the raw input; information is the output
  • A method converts input into output

Problem Statement

  • A problem statement clarifies tasks to be performed
  • It helps programmers understand the goals
  • The statement should guide interaction with users regarding data input, desired outputs, and the process to get to this output.

Error Handling and Testing

  • Error handling anticipates and describes how the program will respond to incorrect input
  • A testing plan outlines expected input and its corresponding output values

Algorithm Development

  • An algorithm is a set of steps describing a program's operations for task completion
  • Algorithms are represented visually using flowcharts
  • Pseudocode is a text-based description of an algorithm

Flowcharting

  • Flowcharts use symbols to show the direction and flow of operations in an algorithm
  • Specific symbols represent activities such as binary decisions (yes/no questions) or processing steps

Flow Control

  • Decision points in programs define actions to take based on input values
  • Binary decisions involve yes/no (true/false) questions
  • Loops repeatedly ask questions and execute actions

Top-Down Design

  • Top-down design breaks down a problem into a series of high-level tasks
  • Tasks are further divided into smaller subtasks and sequences of instructions to form the algorithm.

Object-Oriented Analysis

  • Programmers identify categories (classes) of inputs in object-oriented analysis
  • Reusability is a key feature, and creating new classes (derived classes) that build upon pre-existing classes (base classes)
  • Specific examples (objects) of a class are created as needed (e.g. multiple employee examples).

Coding

  • Coding translates algorithms into instructions comprehensible by the computer.
  • Programming languages are used for this translation.

Programming Languages

  • Programming languages use particular words and rules.
  • Programming languages allow control of a computer's CPU without knowing hardware details.
  • Different programming languages have different strengths in handling various programming tasks.
  • A programmer has to take into account various factors when selecting a language for a specific project and application (e.g., space requirements, speed required). A variety of languages and tools are on the market and the programming market is diverse.

Integrated Development Environment (IDE)

  • An IDE supports programmers in writing and testing programs

Debugging

  • Debugging involves identifying and correcting errors in programs
  • Logical errors cause programs to run unexpectedly.
  • Runtime errors, such as division by zero are specific types of problems within the program.

Testing and Documentation

  • Internal testing involves in-house groups testing the program
  • External testing involves people representing target users testing the software
  • Beta testing often precedes the final release
  • Documentation and manuals help users utilize the software.
  • Programmatic software goes through specific stages when being released to the market which include: release to manufacturers (RTM), general availability (GA).
