Quiz on transaction concept, serializability, transaction isolation and its levels.
RDBMS transactions are a feature of relational database management systems (RDBMS) that allow users to group multiple SQL statements together. With a transaction-aware RDBMS, users can start a transaction, perform actions, and either commit the results to the database or roll back all of their SQL statements.
Here are some aspects of RDBMS transactions: Concurrency control: A critical aspect of RDBMS that ensures that multiple transactions accessing the same data can execute concurrently without producing incorrect results Transaction manager: Responsible for enforcing the atomicity of transactions, which means that either all the changes made within a transaction are committed to the database or none of them Consistency: Defines the rules for maintaining data points in a correct state after a transaction Durability: Guarantees that changes made by a transaction once it has been committed are permanently kept in the database and will not be lost even in the case of a system failure or catastrophe Isolation: An integral part of database transactional properties that ensures data remains consistent and accurate
Other aspects of RDBMS include: The relational model and Relational algebra.
