2.2. ERP Data Categories Business Data Categories

relatively static data stay valid over a period of time usually describing business entities used repetitively e.g. supplier data (address)

Master Data

short living valid during a transaction only always related to master data e.g. quantities

4. Conclusion

Sytem Data Provision Generation of data (conform to business constraints) Inserting data

Table injections Using the system functions

System Data Stability & Test Data Correlation Defining and checking test case preconditions Using pre- and postambles

Input Data Constraints Annotating object oriented (hierarchical) constraints to behavior models

Input Data Provision Generation of data (conform to business constraints & system state) Data picking in set of existing templates

Research Topics

Research PlansAlternative contributions to Service Integration Testing for eSOA
