Which statement best describes the nature of transactions in Mendix?

The statement that transactions are realized through microflows accurately captures a key aspect of how Mendix manages data changes. In Mendix, microflows are the building blocks for implementing business logic and automate processes, including transaction management. When a microflow is executed, it can carry out a series of operations, such as creating, updating, or deleting entities, and it encapsulates those operations within a transaction.

This ensures that all changes made within the microflow are treated as a single unit of work. If the operations complete successfully, the transaction is committed, and the changes are saved to the database. If an error occurs, the transaction can be rolled back to maintain data integrity, ensuring that either all changes are applied or none at all. This functionality is central to building robust applications in Mendix where consistency and reliability of data management are critical.

By executing transactions through microflows, Mendix allows developers to orchestrate complex data manipulations while embedding the transaction logic transparently within their application workflows. Understanding this relationship is vital for effectively using Mendix to develop applications that require transactional data handling.
