Systems Development Life Cycle
The Systems Development Life Cycle (SDLC) outlines the stages involved in creating an application, starting from planning and analysis through to maintenance and eventual obsolescence. It ensures a structured approach to the development and ongoing evolution of information systems.
2 stepsProgram Design
Program design is an essential step before coding, focusing on understanding the program's objectives, utilizing design tools such as pseudocode and flowcharts, and creating test data. This process ensures thorough planning, clear documentation, and testable logic, leading to more efficient coding and easier long-term maintenance.
2 stepsProgram Quality
Program quality encompasses essential attributes of a program’s code, including reliability, robustness, usability, portability, maintainability, efficiency, and readability. These qualities ensure the program functions correctly, handles errors effectively, is user-friendly, and operates efficiently across various systems. A high-quality program is also easy to maintain and update, with clean and understandable code that facilitates future enhancements.
2 stepsPseudocode
Pseudocode is an informal, high-level way of describing a program’s logic using simple, English-like statements. It helps plan and document algorithms before converting them into actual code.
2 stepsFlowcharts
A flowchart is a diagram that visually represents an algorithm or process, using shapes and arrows to illustrate the sequence of steps. It is a useful tool for designing and documenting workflows or programs.
2 stepsSoftware Testing
Software testing ensures a system meets its requirements, handles inputs correctly, and performs efficiently. Test data is used to verify the algorithm and the coded program by predicting expected outputs and identifying any discrepancies.
2 stepsIntegrated Development Environment (IDE)
An Integrated Development Environment (IDE) is a software application that combines essential tools for software development, such as a source code editor, compiler, debugger, and build automation. It streamlines the development process by integrating tasks like coding, compiling, linking, and debugging into a single interface.
2 stepsVersion Control, Git, and I/O Operations
Version control systems, such as Git, track changes in files and support efficient collaboration and code management. Input and output operations handle the exchange of data between systems and external devices.
2 stepsIntroduction to "Hello, World!" Program and Python IDEs
A "Hello, World!" program is a basic introduction to programming, showing the message "Hello, World!" to confirm the setup. In Python, this is done using the print() function.
