Modeling Software Systems in BCA 5th Sem: Unraveling System Modeling

System modeling is the process of representing a software system in a formal and abstract manner to aid in the understanding, design, and communication of the system.

Unified Modeling Language (UML) and Data Flow Diagrams (DFDs)

State Diagrams represent the behavior of a system based on its current state and the actions triggering transitions to new states.

<p>The Customer class represents the individual making purchases, with operations like addAddress, getOrders, and updateProfile. The Order class represents a collection of products purchased by a customer, with operations like getProducts, getTotalPrice, and updateStatus. The Product class represents items available for purchase, with operations like getDescription, getPrice, and getStockQuantity.</p> Signup and view all the answers
