Database Transactions and ACID Properties

Start with transaction basics

The Basic of Data Transaction mind map introduces a transaction as a unit of database operations that should be processed reliably. Start there to see how the page frames the topic. It also mentions recovery and concurrency, giving you terms to look for in the other resources.

Next, open the ACID properties slides. They name atomicity, consistency, isolation and durability. The Transactions mind map adds short explanations, including the idea that a transaction is performed in its entirety or not at all. Compare its wording with the slides as you study.

Use questions alongside the maps

The Transactions flashcard deck asks what ACID stands for and prompts you to explain each property. It also asks about rollback. Try answering each question before looking at the card, then return to the mind maps where you need another view of a concept.

For a broader set of prompts, use Transaction Management. Its questions cover transaction termination, the properties of a transaction and concurrency scenarios. The Transactions & ACID deck also includes questions about rollback and isolation levels. There are no quizzes listed on this page, so these flashcard questions offer a way to practice alongside the maps.

Explore the wider unit

The Database mind map brings ACID and concurrency together, including the idea of multiple transactions executing at the same time. You can use it to revisit terms after working through the flashcards.

This topic is one section of Storage, Query Processing and Transactions in Databases and data science. Keep the unit context in mind as you work through the transaction resources, and use the maps to organize the ideas you encounter. Choose a resource and explore it at your own pace.
