SOFTWARE KNOWLEDGE
Software Knowledge Map
Understand how software systems work from user action to production.
Software systems are built from many connected parts.
Frontend, APIs, backend, databases, security, cloud, testing, and deployment all work together as one system.
Start with the big picture, then explore each layer step by step.
How Software Works
Most software systems follow the same basic pattern.
RUN THE SOFTWARE
Carries requests between software components.
Processes logic and business rules.
Stores application data.
BUILD THE SOFTWARE
How software is built and delivered
