acid-fundamentals

What problem does it solve?

It helps you understand what Atomicity, Consistency, Isolation, and Durability actually guarantee for a database transaction, how configuration changes those guarantees, and how to avoid confusing ACID’s meanings—especially “C”—with other “consistency” concepts.

Core Features & Use Cases

• ACID property definitions you can apply: Atomicity, Consistency, Isolation, and Durability explained as concrete guarantees, including what each property protects against.
• Configuration-aware reasoning: Clarifies how isolation level, replication mode, and durability-related settings change what the application can truly rely on.
• ACID vs BASE and ACID vs CAP clarity: Distinguishes ACID consistency from CAP consistency and maps ACID to the BASE tradeoff model.
• Practical verification checks: Provides verification criteria to ensure your team distinguishes database guarantees from application invariants and doesn’t assume defaults.
• Clear boundaries on when not to use it: Directs users to the correct neighboring skills for isolation-level selection, distributed CAP tradeoffs, schema design, migrations, and replicated design patterns.

Quick Start

Use acid-fundamentals to explain the four ACID properties and how their guarantees change with a database’s isolation level, durability configuration, and replication mode.
