Software Development Processes

  • A structured set of activities required to develop a software system.
  • Many different software processes, but all involve:
    • Specification: Defining what the system should do;
    • Design and Implementation: Defining the system’s organization and implementing it;
    • Validation: Checking that it meets customer requirements;
    • Evolution: Adapting the system to changing customer needs.
  • A software process model is an abstract representation of a process, presenting a description from a particular

Programming Language Fundamentals

A programming language is a set of vocabulary and grammatical rules used to instruct a computer to perform tasks. Learning about programming languages is essential because knowing just one or two languages is not enough for a computer scientist. Studying language concepts improves your ability to:

  • Express ideas more effectively.
  • Choose the right language for different tasks.
  • Learn new languages more easily.
  • Understand implementations of existing languages.
  • Even design

Software Quality: Definitions & QA vs QC

  • Quality: The degree to which software meets specified requirements and customer expectations.

  • Quality Assurance (QA): A preventive, process-oriented activity that ensures quality in the processes by which products are developed.

  • Quality Control (QC): A corrective, product-oriented activity that involves identifying defects in actual products using inspections and testing.

  • Difference between QA & QC:

Software Program Testing Essentials

  • Testing aims to demonstrate that a program functions as intended and to uncover defects before deployment.
  • Software testing involves executing a program with artificial data.
  • Results are checked for errors, anomalies, or insights into the program’s non-functional attributes.
  • Testing can reveal the presence of errors, not their absence.
  • It is a crucial part of the broader verification and validation (V&V) process, which also incorporates static validation techniques.
