The image provides an overview of various system design acronyms essential for software engineers and architects. It breaks down the components of several key principles in software development: - CAP Theorem: Describes the trade-offs among Consistency, Availability, and Partition Tolerance in distributed systems. - BASE: An alternative to ACID for databases, emphasizing basic availability, soft state, and eventual consistency, often used in NoSQL databases. - ACID vs. BASE: ACID is the set of properties for reliable transactions in RDBMS (Relational Database Management Systems), while BASE is more flexible, typically applied in distributed systems. - SOLID Principles: These are five design principles aimed at making software designs more understandable, flexible, and maintainable. - KISS Principle: Stands for "Keep It Simple, Stupid", reminding that systems function best if they are kept simple rather than made complex.
