Information Desk System DFD

Information Desk System DFD – A data flow diagram (DFD) for an information desk system might include the following components:

  1. External entities: These are external entities that interact with the information desk system, such as customers or staff members.
  2. Processes: These are the processes that occur within the information desk system, such as retrieving information or updating records.
  3. Data stores: These are the data stores that the information desk system uses to store and retrieve information, such as databases or file systems.
  4. Data flows: These are the data flows between the external entities, processes, and data stores. For example, a customer might request information from the system, which would trigger a process to retrieve the information from the data store and return it to the customer.

Here is an example of a simple DFD for an information desk system:

[Customer] –> [Request Information] –> [Retrieve Information] –> [Information] <– [Update Records] <– [Staff]

In this example, the customer is an external entity that sends a request for information to the system. The request triggers a process to retrieve the information from the data store, which is then returned to the customer. The staff member is another external entity that can update records in the data store.


The Information Desk System has six modules. They are System Administrator module, officer module, School principal module.

OFFICER MODULE –

This module enables the officer to access the data that has been sent by the school principal. The officer will also return feedback to the school principal.

SYSTEM ADMINISTRATOR MODULE

The module enables the system administrator to perform system and database backup or restore functions. The system administrator may view the audit log, which records all users access to the database. An event log that captures unsuccessful or unauthorized logon to the system is also available.

SCHOOL PRINCIPAL MODULE

In this module the school principal is in charge of the schools activities. He is supposed to collect the required data such as the number of students, the number of teachers, the number of classes, the attendance of both teachers and the students.

MAIN OBJECTIVE
