1. Topic Name Data Flow Diagram for Hotel Management System Presented By Mr. Brajesh Ravikant Bhaisare PGDCCA 1 st Sem Renaissance College Of Computer Science & Advance Technology Bhim Chowk Jaripatka Nagpur – 14

2. The  DFD for Hotel Management System  is an overall flow of how the data moves through a system, describing its inputs and outputs process within the entire system. Furthermore, the  data flow diagram (DFD)  is a graphical representation of the system  data process management  structure. In the case of the  Hotel Management System,  you can edit this template based on your needs. The DFD has three main levels: Context Diagram (Level 0 DFD) Level 1 DFD Level 2 DFD

3. Context Diagram for Hotel Management System The first level in discussing the system’s data flow diagram is the  context diagram . This level shows the system’s core function in a one-line process. Hotel Management System Hotel Administration Employee Customers Accommodation Information Customer Info Job Department List of Customers List of Accommodation Customer Info Accommodation Information Bill Information 0.0 Context Diagram for Hotel Management System

4. In the hotel management process, we have the following external entities: Hotel Administrator Employee Customer These entities will be the main source of data inputs and recipients of data outputs. Remember: This context diagram originated from the common idea of hotel management. Its context can be changed or modified to produce a new and unique project.

5. Level 1 DFD for Hotel Management System Manage Customer Information Assign Rooms & Facilities Manage Reservation Manage Employees Employees Customers Customer Information Customer Status Facilities Information Job Department Employee Information List of Customers Assign Department 1.1 1.2 1.3 1.4 Customer Information Customer Status Bill Information Customer Status Assign Facilities Customer Status Reservation Information

6. This example diagram shows 4 of the sub-processes from the context diagram: Customer Information Management  – is an information system where the customer’s data is validated and used as a basis for other processes just like a reservation. Assigning Rooms and Facilities  – this process may vary according to the request of certain customers. Its assignments are based on the orders of clients and guests (customers). Reservation Management  – are available in the system and are offered to customers online. This business process is one of the core functions of the project. Employees Management  – is the process used by the admin to designate their employees in different departments. This process gathers the employee information and monitors their workloads and performances. These sub-processes show various data processing. Level 2 DFD for Hotel Management System While the former levels focus on processes,  DFD level 2  gives more attention to the other aspects of the project.

7. Manage Customer Information Assign Rooms & Facilities Customer Employee Manage Reservation Manage Employees Customers Database Reservation Database Facilities/Rooms Database Employee Database Customer Info Customer Info 1.1 1.2 1.3 1.4 Rooms/Facilities Details List of Available Rooms List of Available Rooms Assign Employee Reservation List Details List of Employee Employee Info Request Reservation Assigned Accommodation List of Employee

8. For the DFD level 0 (context diagram), it should focus on the main process of the system. The DFD level 1 must elaborate more on the main process sub-processes. DFD level 2 is the project’s highest extraction which means it is the most detailed diagram among the three. But this level only specifies a part of the system or a sub-process from DFD level 1. When you need to specify all aspects of your project, DFD level 2 can be in multiple diagrams. Conclusion In conclusion, we have discussed the role of the drawing data flow diagram  (DFD) levels 0, 1, and 2  for the hotel management system.
