Transaction processing and ACID
A transaction is a single logical operation in a database. Example: Booking a ticket in an airline ticket reservation system. A transaction consists of several actions.
Concurrency: Even though many users can access and edit data at the same time, a database ensures the changes are reflected to all of them.
This A Level Computer Science module introduces transaction processing and ACID to your students, explaining:
- ACID rules
- Issues in multi-user database
- Record locking
- How deadlocks can be prevented?
