Study Notes

Software Design

Software design is the process of defining the architecture, components, interfaces, and characteristics of a system or application.
It plays a crucial part in the software development lifecycle by translating requirements into a representation of the software's structure.

History of Software Design

Early Days (1950s-1960s)

Software design during this era focused on algorithms and efficient use of hardware resources.
Languages like Fortran and COBOL were influential in early design practices.

Structured Programming (1970s)

The 1970s saw a rise in structured programming.
It emphasized modular and hierarchical program design.
Prominent figures like Edsger Dijkstra promoted principles for clearer, maintainable code.

Object-Oriented Design (1980s-1990s)

Object-oriented design (OOD) gained prominence, highlighting modularity, encapsulation, and reusability.
Languages like Smalltalk, C++, and Java popularized OOD concepts.

Component-Based Design (1990s-2000s)

Component-based design (CBD) emerged, promoting software development through reusable software components.
Design patterns emerged as standard solutions to common design problems.

Service-Oriented Design (2000s-Present)

An approach using service-oriented architecture (SOA) and later microservices.
Architecture focused on building applications as loosely coupled services.
Emphasizes scalability, flexibility, and interoperability.

Modern Trends (Present)

Software design continues evolving with agile and DevOps practices.
Practices that support iterative development, continuous integration, and continuous delivery are emphasized.
Design principles, such as Design Patterns, Domain-Driven Design (DDD), and design thinking, are critical to modern software design practices.
