II. Overall Description

1. Product Overview

Website design is an essential element for any business, whether it's a small startup or a large corporation. A well-designed website provides a platform for businesses to interact with their customers, showcase their products and services, and build their overall brand image. In today's digital age, having a website that resonates with your audience is more critical than ever. That’s why the business owner reached out to me and my team hoping to improve their current website. The website will be used to manage their product, their staff and customers.

2. Product functionality

The website has 3 main levels of access: Admin-Staff-Customer. Here is the list of what the website can do: ● Perform basic login function ● Identify user’s role for each login ● Making change to staff’s list ● Making change to customer’s list ● Putting user’s product inside cart ● Removing user’s product from cart ● Generate user’s transaction history ● Updating user’s profile information ● Updating staff’s profile information ● Deleting staff from staff list ● Deleting user from user list III.

1. Design tools

1.1. UML definition

UML(Unified model language) is a standardised modelling language consisting of an integrated set of diagrams, developed to help system and software developers for specifying, visualising, constructing, and documenting the artefacts of software systems, as well as for business modelling and other non-software systems.UML diagrams include class diagrams, use case diagrams, sequence diagrams, state diagrams, and many others.

1.2. Popular UML diagrams

There are two main categories; structure diagrams and behavioural diagrams In Structural diagrams : ● Class Diagram: represents system class, attributes and relationships among the classes. ● Component Diagram: represents how components are split in a software system and dependencies among the components. ● Object Diagram: represents a complete or partial view of the structure of a modelled system In Behavioural diagrams : ● Activity Diagram: represents step by step workflow of business and operational components. ● Use Case Diagram: describes functionality of a system in terms of actors, goals as use cases and dependencies among the use cases.

2. Development tools and techniques

2.1. Cloud

Cloud computing refers to the delivery of IT resources/computing services through the internet (i.e. the "Cloud"). From processing power and storage to software deployment and analytics, these services replace the traditional way of owning physical assets to offer innovation, competitive advantages, flexibility and sharing of resources. The convenience and economics of cloud providers make them increasingly appealing. Cloud deployments are: ● Typically fast and easy to provision. ● Deliver enormous flexibility and are always-on. ● Boost speed and performance. ● Move organisations away from a cash-intensive CAPEX model toward a more budget- friendly OPEX framework.
