What is Deadlock?
A situation where two or more database operations are waiting for each other and none can proceed.
Why It Matters
Deadlocks can freeze parts of your application until detected and resolved by the database.
Real-World Example
Transaction A locks row 1 and waits for row 2, while Transaction B locks row 2 and waits for row 1.
“Understanding terms like Deadlock 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.”
