Travel and Tourism Management System DFD – A data flow diagram (DFD) is a graphical representation of the flow of data through a system. It is used to understand the processes and data inputs and outputs of a system and to identify potential issues or inefficiencies. In a travel and tourism management system, a DFD might include: Processes that represent the different activities that are carried out in the system, such as booking a flight, making a hotel reservation, or generating reports. External entities that represent the sources and destinations of data, such as customers, suppliers, and travel agents. Data stores that represent the storage of data within the system, such as databases of customer information or flight schedules. Data flows that represent the movement of data between processes, external entities, and data stores. A DFD can be organized at different levels of detail, with higher-level diagrams providing an overview of the system and lower-level diagrams showing more specific processes and data flows. The goal of creating a DFD is to provide a clear and comprehensive understanding of the system and how it operates.
Context Flow Diagram
A Context Flow Diagram (CFD) is a type of flowchart that shows the inputs and outputs of a Travel and Tourism Management System. It is typically used to give a clear overview of the system and its functions. The CFD is also used to identify any disconnection between business activities and business objectives. It typically consists of overall application dataflow and processes of the system. A CFD typically contains all of the userflows and their entities such as customers, travel agents, packages, transportation, booking, hotels, tours, etc. It can be exported as a PDF for high-quality printouts.
Travel and Tourism Management System DFD
The Top Level Data Flow Diagram (DFD) of a Travel and Tourism Management System is a graphical representation of the “flow” of data through an information system. It is typically used to give a clear overview of the system and its functions. The DFD typically contains all of the userflows and their entities such as customers, travel agents, packages, transportation, booking, hotels, tours, etc. It can be exported as a PDF for high-quality printouts. The Top Level DFD can also be used to identify any disconnection between business activities and business objectives. Additionally, it can help to identify areas for improvement and to streamline processes.
