Abstract: The invention relates to method and system for creating a data model. The method includes receiving input to create process entity via first User Interface (UI). The process entity is configured to act as first-class citizen. The method further includes creating node corresponding to process entity to generate nodal network via second UI; dynamically receiving attributes associated with selected entity via the first UI; annotating node corresponding to the selected entity based on the attributes received via the second UI; and dynamically creating link between first and second nodes in the nodal network via the second UI. The second UI includes nodes. The link creation includes receiving selection of the first node; receiving selection of the second node; generating the link between the first node and the second node; and receiving direction input associated with the link; and defining direction of the link between the first and second nodes.

Abstract: Embodiments of the present disclosure provide a system and a method for designing and developing an Application Programming Interface (API). The method includes receiving selection of one or more data objects of a relational structure corresponding to an API from a user through a User Interface (UI), and generating a selected response data structure comprising each of the one or more data objects. The method further include receiving a selection of one or more data object filters corresponding to the selection of the one or more data objects, from the user via the UI, and receiving a user request for the API, via the UI, corresponding to the data object of the one or more data objects. The method further include displaying API response data based on the user request, via the UI.
