fetch and modify data in another application

fetch and modify data in another application

hi
i found already a 4 yr. old answer to this topic - so if nothing changed with Creator 5 i will use this approach. - create a function that provides the data in App A
- call this function in App B and fetch the data

same with modification of data

or is there a more elegant approach in Creator 5? eg. something more "query-like"
thank you
kind regards
Lambert
