Study Notes

Solutions to Software Crisis

Effective solutions include spreading software engineering practices and enhancing software engineering disciplines.

Difference between Software Product and Program

Development: Programs are created by individual users for personal use; software products are developed for broad user bases.
Functionality: Programs typically possess limited functionality; software products are more complex and comprehensive.
Documentation: Software products include detailed documentation like SRS, design documents, and user manuals, while programs may lack substantial documentation.
User Interface: Software products require good graphical user interfaces, unlike many individual programs.
Team Development: Software products are developed collaboratively by teams of engineers, whereas programs are often developed solo.
Examples: A sorting program vs. a word processing software product.

Software Process and Layered Technology

Software engineering incorporates layered technology focused on quality, processes, methods, and tools.
Quality management is essential; the process layer serves as the foundational element.
Emphasis on reusability of software components is increasing, seeking to utilize libraries of reusable algorithms and design structures.
Component engineering is emerging as key, allowing developers to use in-built components like GUI elements.

Categories of Software

System Software: Collections of programs that enable other programs (e.g., compilers, editors).
Application Software: Standalone programs tailored for specific business functions.
Engineering/Scientific Software: Covers a wide range of complex computations across various scientific fields.
Embedded Software: Resides within products or systems, controlling features and functionality.
Web Applications: Comprise web pages created using languages like Java, CGI, and HTML.
Artificial Intelligence Software: Encompasses expert systems useful for robotics, image recognition, and more.

Goals and Objectives of Software

User Requirements: Understanding and satisfying end-user demands is critical for software development.
Reliability: High reliability is essential to avoid costly mistakes and maintain customer trust.
Maintenance Costs: Designs should minimize restructuring when updates are needed.
Timely Delivery: Systematic development aids in meeting deadlines.
Production Costs: Developing cost-effective software products is important.
Performance: Optimized speed and memory usage are key for high performativity.
Reusability: Enabling the reuse of software across systems can enhance reliability and reduce costs.

Challenges in Software Engineering

Legacy Systems: The maintenance and updating of old but valuable systems present significant challenges in software engineering.
