Hotel Management System Quiz

While working on a hotel management system, your task is to visualize how guest information flows between modules without detailing the order of steps or control logic. Which diagram would best represent this?

• Use a flowchart to show step-by-step logic

• Draw UML activity diagram with system decisions

• Use a data flow diagram to map information

• Make a structure chart to display process levels

Your manager asks you to design a system diagram that gives stakeholders a basic overview of how the reservation system interacts with outside entities, without internal process breakdown. What should you use?

• Level 1 DFD with internal module grouping

• Level 2 DFD showing all subprocess flows

• A UML class diagram with actor interactions

• A context diagram for a high-level overview

You are tasked to create a software module and have identified that some functions will be reused frequently across various parts of the program. What component in a structure chart is best suited for this?

• Make it a sub-module under another control

• Label it a library module for reusability

• Add it as a looped control process

• Use a condition diamond for logic control

During a DFD peer review, your colleague notices a process box without any arrows leading in or out. What is the most valid reason to correct this?

• Every DFD process must link with data

• DFDs may exclude flows for internal steps

• Processes can exist independently if descriptive

• The system handles internal routing automatically

In your hotel system DFD, you mistakenly routed data from a data store directly to another data store without passing through a process. What rule did you violate?

• DFDs require distinct actor identification

• Data must flow through a process first

• Loops are forbidden between data stores

• Only outputs can link data stores

Your team wants to break a top-level system process into sub-processes to analyze how guest details are checked, stored, and confirmed. Which DFD level should you use?

• Context diagram for executive summary

• Level 1 to split major components

• Level 2 for external actor relationships

• Flowchart for module description only

You are viewing a structure chart where a small diamond appears beneath a module. What feature is this likely representing?

• A repeated function for data processing

• A conditional module selection process

• A termination point in a submodule

• A user input-triggered data loop

During system visualization, you see a curved arrow looping over multiple modules. What does this imply in a structured chart?

• Submodules return output to upper level

• Modules operate in a fixed order always

• A loop executes the modules repeatedly

• A decision control runs each module once

You're documenting high-level functions for hotel management to review. You want something clear and hierarchy-based, without showing how the data flows or is controlled. Which is most appropriate?

• Structured chart with submodule expansion

• HIPO diagram for clean documentation

• UML sequence diagram with steps

• DFD Level 2 with technical breakdown

A new programmer joins your project. To help them write accurate code, you want to avoid ambiguous diagrams and instead use plain logic-based text. What should you provide?

• Structured English for logic instructions

• UML diagram with symbol interpretations

• Context diagram for visual user flow

• Class model using object and attributes
