The Erasmus insurance case and a related questionnaire for distributed database management systems
This is the third report concerning transaction management in the database environment. In the first report the role of the transaction manager in protecting the integrity of a database has been studied [van der Made-Potuijt 1989]. In the second report a model has been given for a transaction manager as a parallel decision process [van der Made-Potuijt & Groenewegen 1990], In this report a case, the Erasmus Insurance Case (EI-Case) will be presented that can be used to test transaction management in a centralized and distributed environment. It can also be used to describe transaction management in a distributed environment as parallel decision processes. The purpose of the questionnaire is to investigate the functionality of a particular distributed database management system. The answers of the questionnaire can be certified by tests on an implementation of a case. To this aim tests are added to the questions, referring to the implementation of the EI-case in the Distributed DBMS under investigation.
