Spring transaction management simply means: How does Spring start, commit, or rollback JDBC transactions. 4) Durabilityĭurability guarantees that once the transaction commit and changes are written to the database, they will persist even in the case of system failures like crashes or power outages.Īs a result, the transaction's modifications are never undone.
Isolation ensures that the intermediate state of a transaction is invisible to other transactions.Īs a result, transactions that run concurrently don't interfere with each other. If the data gets into an illegal state, the whole transaction fails. 2) ConsistencyĬonsistency guarantees that the data is in a consistent state when a transaction starts and when it ends. The transaction would have either completed successfully or been rolled back if any part of it failed. 1) AtomicityĪtomicity guarantees that all the commands in a transaction (to read, write, update, or delete data) are treated as a single unit and either succeed or fail together.
propertiesĪCID is an acronym that stands for atomicity, consistency, isolation, and durability.ĪCID properties ensure that a database transaction (a set of read, write, update, or delete operations) leaves the database in a consistent state even in the event of unexpected errors. Transactions can impact a single record or multiple records. A database transaction is any operation that is treated as a single unit of work that either completes fully or does not complete at all and leaves the storage system in a consistent state.
