Hi Ali,
thanks for your follow-up. soapUI 1.8 is likely to have improved reporting / exporting functionality for LoadTests.. but 1.7.6 will actually add a possibility to plug in custom listeners (written in java or groovy) into various events "inside" soapUI, including the execution of a LoadTest.. so if you need this "desperately" we will try to help you create your own plug-in for this until it is supported by the UI..
Regarding the database schema, when we integrate this you will likely need to follow some pre-defined schema, with the above mentioned possibility you will have full freedom to define your own schema/persistence mechanism.
stay tuned for more info on this together with the 1.7.6 release next week.
regards!
