Q8
Single choice
In an order process, three JDBC queries need to be executed against three separate databases: 1.
Decrease inventory by the ordered volume to reserve inventory (in the inventory database) 2. Check the customer credit limit in a table (in the customer database) 3. Insert the order details in the order table (in the order database) If, for example, the credit limit check fails, the inventory needs to be restored.
Which service can be of help in this situation?
