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).
