Loop cards are a great game that can be played individually or as a class. They are perfect for review key vocabulary or questions at the end of a topic or when revising for an exam.
Instructions
Cut out the cards from the paper horizontally (but don't cut them in half!) and then shuffle them.
Now start joining each question on the right hand side of the card to the matching answer on the next card.
Carry on until all the cards loop together and you have competed the game!
Hint: Make sure that you set your paper to portrait to print 4 cards per sheet of A4 paper.
A concurrency control technique in database systems where transactions are ordered based on their timestamp values.
Serialization
Ensuring that the execution of multiple transactions produces the same result as if they were executed sequentially.
Commit
The final step of a database transaction where all changes made within the transaction are permanently saved.
Isolation Level
A property that determines how concurrent transactions interact with each other and the level of data visibility.
Two-Phase Locking

Record
A single, complete set of information within a table.
Database Transactions
The process of performing multiple database operations as a single unit of work, ensuring consistency and integrity of data.
Undo Log
A mechanism used in the recovery process of a database to revert the effects of incomplete or aborted transactions.
Concurrency Control
