A practical approach for detecting multi-tenancy data interference

The implemented support tool prototype demonstrates the method's effectiveness for supporting the transformation of single-tenant legacy source code into multi-tenant components or microservices. It could also be used to confirm that multi-tenant components or microservices are free of data interference defects. The prototype implementation has been validated in a case study with code from the open-source enterprise application SugarCRM. Results indicate that the developed approach significantly increases the efficiency of multi-tenancy transformation in larger code bases by pointing out potential defects.
