+## Notes
+As I'm rather Johnny then the one that writtes a library for Johnny, I focused on using the created service in the front end. 
+The Concept is a CRUD Application based on firestore.
+I didn't think it's neccesary to split it in two services. I thought it makes more sense if the transaction know to which user/account they belong instead of having an additional account object.
