What are UML Diagrams?


UML diagrams are based on the UML (Unified Modeling Language) used to describe the E-Commerce Website. It includes the major actors, roles, actions, artifacts, or classes, in order to better understand the information.

Software engineers uses UML modeling language to create diagrams. That is to provide ready-to-use, expressive modeling examples to users (programmers). The UML Diagrams are categorized into two types: the structural diagrams and the behavioral diagrams.

The Structural UML Diagrams represents the rightful structure and features of the E-Commerce Website. On the other hand, the Behavioral UML Diagrams illustrates the System’s behavior towards the users and data handling.

What is E-Commerce Website UML Diagram?


The UML Diagrams are part of project documentation that represents the overall E-Commerce Website. Each of these diagrams shows different visualization of E-Commerce Website structures and behavior. That is to know how the system handles data and interact with the targeted users.

Is it necessary for E-Commerce Website to have UML Diagrams?


The answer is “yes.” It’s because the UML diagrams are the blueprints of the system’s structure and behavior. Structural diagrams help in building the structure of an E-Commerce Website. The behavioral diagrams, on the other hand, help in determining the system’s behavior towards the user and data processing. All of the UML diagrams work in sync and relatively to achieve a well-engineered project.

How to build E-commerce Website UML Diagrams?

Time needed: 5 minutes.

The UML Diagram development steps and guidelines are provided here. You don’t have to burden yourselves because each of these steps were also applied in the UML diagrams developed.

  1. Step 1: Gather Information

    The first thing that you must do before building UML Diagrams for the website is to collect as much e-commerce data as you can. You’ll need to know how they manage products’ information and processing customer transactions.

    You must complete all the necessary information in order to provide a quality software for them. Then you’ll apply the data gathered in designing the UML diagrams.

  2. Step 2: Evaluate

    After gathering much information, you will have to evaluate them. You will only include the important processes done in e-commerce website. The targeted users can help you in evaluating the needed processes. Then you will convert them into modules or features.

  3. Step 3: Start creating your Blueprint.

    The blueprints stands for the diagrams that you’ll create. The information gathered and evaluated will be the important basis in creating it.

    You will start segregating all the data according to the entities that needed to be emphasized. Example of which are:
    • Class Diagram – focuses on data structures.
    • Use Case Diagram – focuses on processes.
    • Sequence Diagram – focuses on sequences of events.
    • Activity Diagram – focuses on users’ activities or interactions with the system.

E-Commerce Website Project UML Diagrams:

The purpose of building the website is to provide the seller and buyers the easier and efficient way of doing purchase and endorsing products. And in order to do that, you have to complete the needed diagrams to perfectly furnish your project. Build your project completely using UML Diagrams to help you and keep you from errors.

Sequence Diagram

The designed sequence diagram shows the series of events that occurs in E-Commerce Website. The actors are represented by a stick man and the transactions or classes are represented by objects. This gives you clear explanation E-Commerce Website behavior in terms of processing the flow of instructions.
