A relational database like SQL is a collection of data items organized in tables. ACID is a set of properties of relational database transactions. |
|
|
|
- **Atomicity** - Each transaction is all or nothing |
|
- **Consistency** - Any transaction will bring the database from one valid state to another |
|
- **Isolation** - Executing transactions concurrently has the same results as if the transactions were executed serially |
|
- **Durability** - Once a transaction has been committed, it will remain so |
|
|
|
There are many techniques to scale a relational database: master-slave replication, master-master replication, federation, sharding, denormalization, and SQL tuning. |
