Design Model || SOFTWARE ENGINEERING

Summary

In this session, the presenter explores the two dimensions of board design: process and abstract. The process dimension tracks the design's evolution from requirements gathering to the final model, while the abstract dimension delves into the detailed information of each element. The design model comprises four key elements: data, architectural, interface, and component design elements. Each element is crucial, with data focusing on business logic and database access, architectural on the software's structural view, interface on user experience, and component on the software's internal structure. The session concludes with a look at deployment, emphasizing the importance of delivering a complete, high-quality product to the user.

Takeaways

• 📊 The board design model has two dimensions: process and abstract, which help in understanding the evolution and detailed information of design elements.
• 🔍 The process dimension shows the changes in the design model from requirements gathering to the final design.
• 🔎 The abstract dimension provides a detailed view of each element in the design model.
• 💾 Data design elements are crucial for business logic and database access, organized at component, application, and business levels.
• 🏢 Architectural design elements are like a floor plan for software, focusing on the overall structure and considering application information, specific requirements, and availability of styles and patterns.
• 📱 Interface design elements aim to provide a good user experience, including external interfaces to other systems, networks, and internal interfaces between components.
• 🔗 External interfaces are essential for interactions with other systems, like the driver and admin apps in a delivery service app.
• 🏭 Internal interfaces are necessary for the interaction between different modules in a system, such as an ERP system.
• 🛠️ Component design elements focus on the internal structure and finishing of the software, ensuring reusability and proper functionality.
• 🚀 Deployment level elements are about delivering the complete software product to the user, ensuring availability and proper deployment.

Q & A

What are the two dimensions of board design model discussed in the session?

The two dimensions of board design model discussed are the process dimension and the abstract dimension.

What does the process dimension of the design model represent?

The process dimension represents the evolution of the design model, showing the changes from the analysis phase to the design model, including requirements gathering.

How is the abstract dimension of the design model described?

The abstract dimension allows us to see the detailed level of information of each element in the design model.

What are the four major elements of the design model?

The four major elements of the design model are data design elements, architectural design elements, interface design elements, and component design elements.

What is the role of data design elements in the model?

Data design elements create a model that contains every business logic and database access class, and they operate at component, application, and business levels.

Can you explain the component level in the context of data design elements using the example of a flip cart?

At the component level, using a flip cart as an example, the main goal is to deliver a high-quality product to the customer in the right way, maintaining high standards.

What is the significance of architectural design elements?

Architectural design elements provide a view of the software, similar to a floor plan of a house, and they need to consider information about the application, specific requirements, and availability of styles and patterns.

How does the interface design model contribute to user experience?

The interface design model aims to provide a good user experience by focusing on user interfaces, external interfaces to other systems, various networks, and internal interfaces between design components.

What are the three important elements to consider in interface design models?

The three important elements to consider in interface design models are user interfaces (UI), external interfaces to other systems, and internal interfaces between various design components.

Why are component level design elements important in the IT industry?

Component level design elements are important in the IT industry due to their reusability and the detailed internal structure and finishing they provide, which are crucial for the software's functionality and quality.

What does deployment level of elements entail?

The deployment level of elements involves making the complete software product available to the user, ensuring proper deployment to meet the customer's needs.
