What is Transaction (Database)?
A group of database operations that either all succeed or all fail together.
Why It Matters
Transactions prevent your data from ending up in an incomplete or inconsistent state.
Real-World Example
Transferring money involves debiting one account and crediting another. A transaction ensures both happen or neither does.
“Understanding terms like Transaction (Database) 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.”
