You are an IT intern working for a small accountancy firm. During the COVID hard lockdown

period, the firm realised that it has to be more adaptable if it is to survive and as such have
decided to develop an application that will allow clients to make use of the firm’s services via an
online platform. The IT department of the accountancy firm will be developing this new online
platform.When a user enters their details on the home page of the application, the client management
subsystem will confirm whether they are a registered user or not. If they are a registered user,
their identity will be verified and they will be able to select a service action such as a statement
request or a tax filing request from the services subsystem. If they are not a registered user, the
system will register a profile for them based on the information they provided, verify their identity
and allow them to select a service action. As yearly tax submissions are time sensitive, the
platform should be available 24 hours a day, 365 days a year.All systems analysis activities have been concluded for the application to be developed for the
accounting firm. It was decided that the application will run through a web browser to ensure
greater portability of the application. It will only interact with the company’s internal databases
for the time being. All data inside the database will be encrypted.
Answer all questions in relation to the development of the application for the accounting firm.
When a client registers a profile using the application, they provide their name, surname, address,
ID number, tax number
Q.5.2 Explain how you will convert class Client to a table that will form part of a
relational database.

1 answer

To convert the class Client to a table in a relational database, we need to map the attributes of the Client class to columns in the database table. Each attribute of the Client class will become a column in the Client table in the database. Here is how we can map the attributes of the Client class to the columns in the database table:

- Name (varchar): This will be stored as a varchar data type in the database to store the client's name.
- Surname (varchar): This will also be stored as a varchar data type in the database to store the client's surname.
- Address (varchar): The address attribute will be stored as a varchar data type in the database to store the client's address.
- ID number (varchar): The ID number attribute will be stored as a varchar data type in the database to store the client's ID number.
- Tax number (varchar): The tax number attribute will also be stored as a varchar data type in the database to store the client's tax number.

In addition to the above attributes, we will also need to include a unique identifier for each client, such as a client_id, which will serve as the primary key for the Client table. This primary key will ensure that each row in the Client table is uniquely identified.

By creating a table in the relational database that mirrors the structure of the Client class, we can effectively store and manage client information in the database as part of the application's functionality.
