What is ACID?
A set of properties (Atomicity, Consistency, Isolation, Durability) that guarantee database transactions are reliable.
Why It Matters
ACID compliance ensures your data stays correct even when things go wrong, like power failures or concurrent writes.
Real-World Example
A bank transfer either completes fully or not at all. ACID prevents money from disappearing or doubling.
“Understanding terms like ACID matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
