Database Management Systems | Data Flow Diagram | Context or Zero Level DFD | S403P ShortLectures

In this session of Database Management System Labs – CS403P, we explore one of the most important system modeling tools: the Data Flow Diagram (DFD). This video covers the complete foundation of DFD in a simple and practical way. You will learn: What a Data Flow Diagram (DFD) is Why DFD is used in system analysis and design The core components of a DFD (Process, Data Flow, Data Store, External Entity) The concept of Context / Zero-Level DFD Three real-world examples explained step by step Whether you are a Computer Science student, IT student, or preparing for exams, this lecture will help you clearly understand how systems interact with users and how data moves within a system. By the end of this video, you will be able to confidently draw and interpret basic DFDs for real-life scenarios. #CS403P #CS403Labs #DatabaseManagementSystems #DataFlowDiagrams #DFD #ContextLevelDFD #CS403 #CS504 #VirtualUniversity #M
