Which of the following model is used to show how data flows through a sequence of processing steps?

Explanation

Data flow model It is a diagrammatic representation of the flow and exchange of information within a system. Data flow models are used to graphically represent the flow of data in an information system by describing the processes involved in transferring data from input to file storage and report generation. Additional Information Object model It is a logical interface, software, or system that is modeled through the use of object-oriented techniques. It enables the creation of an architectural software or system model prior to development or programming. An object model is a part of the object-oriented programming (OOP) lifecycle. Semantic data model It shows objects and their relationships in a format that highlights the real world (versus technical jargon). In a semantic diagram, we display objects and their relationships to other objects (an album contains songs). System modeling It is the process of developing abstract models of a system, with each model presenting a different view or perspective of that system. It is about representing a system using some kind of graphical notation, which is now almost always based on notations in the Unified Modeling Language (UML). Models help the analyst to understand the functionality of the system; they are used to communicate with customers Hence Option 4 is correct
