Could anyone help me distinguish the difference or relation between SIBS (Silverlake Integrated Banking System) and AS/400. Is it a built-in solution of AS/400 or a separate solution? And it's AS/400 is object based design which APP, OS and DB are integrated, how the use access to those layer (APP, DB & OS) work. eg. having an ID can access to all layers or else?
Thanks for all your response to my questions.
