 Conceptual design implements and evaluates covid-19 for generic for systematic data transfer and data capturing methods. The report will describe the physical and social aspects of the system. It will enable an understanding of the representative model. Promote practical knowledge of system details among the team members. And the provision of a point of reference about the system for future specification gathering. It will capture key business entities like a person, place, concepts, and specific events.   

 

 System decomposition 

 

                                                                                                                                                                                     

 

 

 

 

 

 

 

 

 

 

 

 

 There is a high-level design and architecture of the system. The essence of the system architecture is breaking down the system into its comprising components. The system is decomposed into a login page where a person enters personal information like name, email, city of birth, and current city. The critical key becomes the ID or Passport number, which are then submitted to allow access to the system. 

 LOGIN page will be represented as 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 After entering the details, the system will access the next page, where one will answer a Questionnaire. The questionnaire will involve open-ended questions to a patient. Patients will have to respond with either a yes or no.

 

• Did you travel to the Covid areas?

• Do you cough?

• Do you have a sour throat?
• Do you have a sense of test?

• Do you have a headache?

•  Do you have breathing difficulties?

 

 

 The system will ask the system to upload documents, which will be verified to determine if they are valid documents for the covid-19 test. If they are valid OR not correct, a QRCODE will be generated. The code will be put on a bar code reader to grant access or not. The system has an interrelationship in that the provided information through a questionnaire, when submitted, is used to generate a Qr Code. The uploading of Covid-19 certificates helps to determine if the person has been tested or not. 

 

Functionality

Then QR will be used for giving or denying access to a supermarket or an office. 

 The system will test if a  person has undergone the covid-19 test or not.

It will determine the number of positive or negative patients through data sampling on the specific areas the persons are staying. 

It will report positive cases by answering the questionnaires. 

 Non-functionality

The system wil not be used for contact tracing.

It will not test positive or negative people but will get information through a questionnaire and verification of Covid related documents.
