Introducing the CUB Methodology: A Fresh Approach to Software Development

Software development is a complex process that requires careful planning and execution. The CUB methodology is a new approach that combines [Scrum framework ](https://www.scrum.org/resources/scrum-guide)and [UML design principles](https://www.visual-paradigm.com/guide/uml-unified-modeling-language/what-is-uml/) to create a more efficient and effective development process by focusing on three main stages of software development; **create**, **update** and **behave**.

## Create
First up is Create. This is where the development team collaborates with the Product Owner to create a product backlog. To help with this process, they use UML use case diagrams to model the interactions between users and the system, and UML class diagrams to model the structure of the system.

## Update
Once the product backlog is created, it's time for the Update stage. This is where the team adapts their processes and practices based on feedback received from the previous sprint. To aid in this process, they use UML sequence diagrams to model the interactions between objects in the system over time.

## Behave
Finally, there's Behave. Throughout the development process, the team must ensure that the system behaves as intended. To help with this, they use UML object diagrams to model specific instances of classes and test how objects interact with each other. They also use UML component and deployment diagrams to model the physical components of the system and make sure they're deployed correctly.








Let's take a closer look at how the CUB methodology can be applied to both front-end and back-end development.

# Front-End CUB: Creating Robust and Responsive Web Applications
The CAB method can be applied to front-end development to create robust and responsive web applications. The following is a breakdown of how the CAB method can be used in front-end development:

### Create:
UML class diagrams can be used to model the structure of the web application.
In the "Create" phase, the front-end development team can use Server-side Rendering (SSR) to create the initial structure of the web application. SSR generates the HTML for a web page on the server-side and sends it to the client-side for display. This ensures fast loading times and better search engine optimization (SEO). 

### Update:
Client-side Fetching and First Web Paint techniques can be used to improve the user experience. UML sequence diagrams can be used to model the interactions between client-side and server-side components of the web application.
In the "Update" phase, the team can use Client-side Fetching and First Web Paint techniques to improve the user experience. Client-side Fetching allows the client-side to fetch data asynchronously and dynamically from the server, improving the web application's performance. First Web Paint is the first time the user sees the web application displayed on their device. The team can optimize the First Web Paint experience by reducing the time to first paint and improving the perceived load time.

### Behave:
Reactivity and Routing can be implemented to create a reactive web application.
UML component diagrams can be used to model the physical components of the web application, including the various pages and their relationships.
In the "Behave" phase, the team can focus on creating a reactive web application by using frameworks such as React or Vue. These frameworks allow for real-time updates of web application data without requiring the page to refresh. UML object diagrams can be used to model specific instances of classes and to test how objects interact with each other. Routing can be implemented to ensure that the web application's different pages are accessible and navigable.

# Back-End CUB: Creating Scalable and Secure Web Applications
The CUB methodology can be applied to back-end development to create scalable and secure web applications. The following is a breakdown of how the CUB method can be used in back-end development:

### Create:
In the "Create" phase, a web server is set up with a server-side programming language like Node.js, Python, or PHP. The server is configured to handle HTTP requests and responses. UML use case diagrams can be used to model the interactions between users and the system.

### Update:
In the "Update" phase, the team adapts their processes and practices based on feedback received from the previous sprint. The system is adapted to work with a database management system like MySQL or PostgreSQL. Stored procedures can be created to execute database commands repeatedly. UML sequence diagrams can be used to model the interactions between objects in the system over time.

### Behave:
In the "Behave" phase, the team should focus on ensuring the system behaves as intended. A router can be created to map URLs to the appropriate code in the back-end. Controllers can be created to handle the business logic of the system. Security measures can be implemented to protect the system from unauthorized access. Logging and monitoring can be set up to track system performance. UML component and deployment diagrams can be used to model the physical components of the system and to ensure they are deployed correctly.

## Conclusion
Overall, the CUB methodology can help software development teams create robust and secure back-end systems by focusing on the creation, updating, and behavior of the system. By using UML diagrams to monitor progress, communicate with stakeholders, and ensure everyone is on the same page, software development teams can streamline their work and deliver high-quality systems. Give the CUB methodology a try in your next software development project and see the difference it can make!
