How do you initiate a database transaction in Avaloq Script?

Initiating a database transaction in Avaloq Script specifically involves the use of the "beginTransaction()" function. This function is designed to start a new transaction in the database, allowing for a series of operations to be executed as a single unit. By doing so, it ensures that either all the operations are successfully completed and committed to the database, or none of them are applied, maintaining data integrity.

The choice of "beginTransaction()" is grounded in the way transaction management works within database environments, where controlled starting and ending of transactions is crucial for consistency and reliability. Other options involve functions related to transactions but do not serve to initiate them. For instance, "commitTransaction()" is used to finalize and save the transactions that have been started, while "startTransaction()" and "openTransaction()" are not standard functions used in Avaloq Script for initiating transactions. The distinction is important for understanding transaction flow within the framework of Avaloq Script.
