Abstract: Systems and methods consistent with certain embodiments of the invention relate to optimization of hierarchy screen refreshes in a graphical user interface. According to one exemplary embodiment, a method for refreshing a graphical user interface that includes a navigation hierarchy is disclosed. The method comprises storing a first representation of the navigation hierarchy at a front end system and a second representation of the navigation hierarchy at a back end system, the second representation being a reduced version of the first representation. The method receives a user interaction with the graphical user interface and sends user inputs to the back end system if the user interaction triggers an event. The method determines at the back end system an updated representation of the navigation hierarchy based on the user inputs, without requesting the first representation of the navigation hierarchy from the front end system.
