Industrial Information system

Assignment # $1$

Question $1$:

Create a Level$-1$ IDEF$0$ Diagram for the Order Fulfillment Process of an online retail company. The diagram should model the process of receiving customer orders, checking inventory, processing payments, packing, and shipping the order.

Your diagram must include the following for each function $($A$1,$ A$2,$ A$3,$ etc.$)$:

Inputs: What triggers or initiates the function? $($e$.$g$.,$ customer order, payment information$)$

Outputs: What is the result or product of the function? $($e$.$g$.,$ packed order, shipping confirmation$)$

Controls: What rules, policies, or conditions guide the function? $($e$.$g$.,$ inventory availability, order policies, payment authorization rules$)$

Mechanisms: What resources or tools are required to perform the function? $($e$.$g$.,$ warehouse staff, order processing software, shipping equipment$)$

You are required to: Provide a single top$-$level diagram $($A$0)$ that represents the Order Fulfillment Process as a whole. Decompose it into at least four main functions $($A$1,$ A$2,$ A$3,$ A$4)$ on the Level$-1$ diagram. Clearly label all inputs, outputs, controls, and mechanisms using proper IDEF$0$ notation.

Question $2$:

Create a Data Flow Diagram $($DFD$)$ for the Student Registration System at a university. The system allows students to register for courses, view their schedule, and make payments for tuition.

Your DFD should:

Be a Level$-1$ Diagram showing the main processes, data flows, data stores, and external entities involved in the registration system.

Model at least four key processes $($e$.$g$.,$ registering for a course, generating schedules, managing student data, processing payments$).$

Clearly represent:

Processes: Show how data is transformed within the system $($e$.$g$.,$ "Process Registration" or "Generate Schedule"$).$ Data Flows: Represent how data moves between processes, data stores, and external entities $($e$.$g$.,$ student details, payment confirmation$).$ Data Stores: Identify where data is stored $($e$.$g$.,$ "Student Database" or "Course Catalog"$).$ External Entities: Show interactions with external users or systems $($e$.$g$.,$ students, financial office$).$

Make sure to provide a high$-$level view of how the system works, with a focus on the flow of data between components.
