ACID Principles
Foundations ✓ → SQL & safety → Production → Projects
SQL & safety · 2 — Procs, tx, performance · ~6 min · Module 4: Transactions and Error Handling
What is this?
ACID — Atomicity, Consistency, Isolation, Durability — is what ShopNest money SQL relies on.
Why should you care?
Without ACID, retries and partial failures corrupt wallets.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
// Atomicity demo
await using var tx = (SqlTransaction)await conn.BeginTransactionAsync(ct);
// ... two updates ...
await tx.CommitAsync(ct); // both durable togetherWhat happened?
- Transactions give A and help C/I/D with engine support.
- Choose isolation for I; commits for D.
Practice next
- Name each letter with a ShopNest example.
- Show rollback atomicity.
- Discuss durability after commit.
- Break mid-tx and verify undo.
- Read committed vs snapshot one-liner.
Remember
A=all or nothing. Match isolation to need. Commit = durable.
ShopNest ledger ACID
Wallet posts only via transactions.
Outcome: Auditors trust balances.
