Understanding MVC Framework and Web2py

Introduction to MVC Framework

The Model-View-Controller (MVC) framework is an architectural design pattern that separates an application into three main logical components: Model, View, and Controller. Each component is built to handle specific development aspects of an application.

  • Model: This component corresponds to all the data-related logic that the user works with. It can add or retrieve data from the database.
  • View: This component is used for all the UI logic of the application. It generates a user interface for the user.
  • Controller: The controller processes all the business logic and incoming requests, manipulates data using the Model component, and interacts with the View to render the final output.

The MVC framework isolates the business logic and presentation layer from each other. It was traditionally used for desktop graphical user interfaces (GUIs), but nowadays, MVC is one of the most frequently used industry-standard web development frameworks to create scalable and extensible projects.

What is a Web Application

Web applications differ from conventional websites in terms of the content they display to the user. Web applications can process user input and react to it. They are able to store and retrieve data and present it to the user in a web browser. One could say that conventional websites are for consumption and web apps for interaction.

Introduction to Web2py

Web2py is a free, open-source web framework for agile development which involves database-driven web applications. It is written and programmable in Python. It is a full-stack framework and consists of all the necessary components a developer needs to build fully functional web applications.

Web2py framework follows the Model-View-Controller pattern of running web applications. It separates the data representation (the model) from the data presentation (the view) and also from the application logic and workflow (the controller).

Conclusion

Understanding the MVC framework is crucial for modern web development. It provides a clear structure for designing web applications, making the development process more manageable. Web2py is an excellent example of a full-stack framework that utilizes the MVC pattern, providing a robust platform for building database-driven web applications. Runestone is also modern web development. A user is able to login, and access their library and interact with the book of their choice. Runestone gives the option to do self-grade evaluation. MVC framework allows the interactivity that a user gets from Runestone Academy textbooks which make Runestone unique.

  After hearing from Dr. Brad Miller, what are your first impressions about Runestone as an open-source project? Please explain. After hearing from Dr.Brad Miller I am amazed at the process of how Dr.Miller was able to successfully bring this project alive. It started off as just an idea which I thought everyone would love because I personally know how effective and useful it is to students today, but hearing that there were some people that did not want their textbooks published this way, and wanted to keep things the way they were surprised me. It is hard to get every single person to agree and get excited about an idea, but I am really happy that Dr.Miller was able to find those that helped him in his journey and partnered with him because they saw his vision. During his talk Dr.Miller mentioned that a lot of his students had helped him, and I specifically remember him mentioning the student that wrote the code for the grade book. Because Runestone has become more popular due to...

Let's do a high-level overview of "a n authoring and publishing system for authors of textbooks, research articles, and monographs, especially in STEM disciplines."  which is called Pretext. As stated in the pretextbook.org website the publishing system is targeted for scientific and textbook-heavy fields. As we all know writing a research paper or publishing something that is STEM-related can be tedious because there are certain rules, and regulations that one needs to follow. Pretext is a markup language, and allows the author to take advantage of the features included within it. One of the big plus of pretext is that it frees up author's mind from having to focus on how the content is displayed, and just focus on the actual content. As technologies are getting more advanced by the day, it can be difficult to keep up and maintain the published content which is another reason why Pretext is convenient. The software of Pretext " keeps up with technical advances a...

  Over the summer as an intern at Bank of America, I got a pretty good insight of how effective Agile practices can be. I have some high-level understanding of what Waterfall model is, and as  Liz Lockhart, PMP and Agile Leader has stated it is " The  waterfall project management method  is a linear, step-by-step approach that's ideal for projects with a clear scope and predictable timeline. It involves rigorous planning upfront to ensure that the project stays on track, with progress tracked closely and issues addressed promptly." As we know, technology is changing and fast paced which is why waterfall model is outdated and cannot keep up with the changing requirements that is required. On the other hand, one of manifestos of Agile methodology is " Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage ." From my personal experience, working with a big company I have seen how effective, ...
