The aim of this thesis was to modify an existing order queue application which was unable to execute orders in a queue in parallel which in turn could lead to a bad user experience due to the increased queue delay. The thesis proposes two queue structures to allow parallel execution within a queue. One of the two is selected for implemented in the modified order queue application. The implementation was carried out in Java EE and used different types of frameworks such as JPQL. Some parts of the order queue application had to be modified to be able to handle the new queue structure. New attributes that defines dependencies of the orders are used to find a suitable parent for each order in the queue. The queue structure was visualized making it possible to see the execution in real time, and a test server was implemented to test the queue structure. This resulted in a working prototype able to handle dependencies and parallel orders. The modified order queue application was performance measured and compared to the original order queue application. The measurement showed that the modified order queue application performed better than the original order queue application in terms of execution time below a certain number of queues. Future work includes optimizing the methods and queries in the implementation to increase the performance and to handle parallelism within the orders.
