The invention proposes a simpler and more efficient method for building a navigation schema in a cloud service broker platform (CSB) that builds a complex user interface (UI) from the CSB platform to an integrated connector application. The present disclosure automates navigation schema generation by obtaining a connector package, transforming a navigation schema therein from a hierarchical form to a plain form, and creating a modified schema for such. The present disclosure further discloses a method for creating a navigation schema template according to chosen placeholders and helps a user to fill in the template, and further check the created schema.
