Aim

This unit aims to provide learners with the knowledge and skills needed to build a Back end web application. Topics covered include data storage and data management using relational databases.

Unit Learning Outcomes

1.

Design, develop and implement a Back end for a web application using Python and a framework.

Assessment Criteria

  • 1.1

    Design a Front end for a data-driven web application that meets accessibility guidelines, follows the principles of UX design, meets its given purpose and provides a set of user interactions.

  • 1.2

    Implement custom HTML and CSS code to create a responsive full-stack application consisting of one or more HTML pages with relevant responses to user actions and a set of data manipulation functions.

  • 1.3

    Build a database-backed web application that allows users to store and manipulate data records about a particular domain.

  • 1.4

    Design a database structure that is relevant to the domain, including relationships between records of different entities.

  • 1.5

    Design and implement test procedures (automated or manual) to assess functionality, usability, responsiveness and data management within the Full Stack web application.

  • 1.6

    Write Python code that is consistent in style and conforms to the PEP8 style guide (or another explicitly mentioned style guide, such as Google's) and validated HTML and CSS code.

  • 1.7

    Write Python logic to demonstrate proficiency in the language.

  • 1.8

    Include functions with compound statements such as if conditions and/or loops in Python code.

  • 1.9

    Write code that meets minimum standards for readability (comments, indentation, consistent and meaningful naming conventions).

  • 1.10

    Name files consistently and descriptively, without spaces or capitalisation to allow for cross-platform compatibility.

2.

Model and manage data .

Assessment Criteria

  • 2.1

    Design a data model that fits the purpose of the project.

  • 2.2

    Develop the model into a usable relational database where data is stored in a consistent and well-organised manner.

3.

Query and manipulate data.

Assessment Criteria

  • 3.1

    Create functionality for users to create, locate, display, edit and delete records.

4.

Deploy a Full Stack web application to a Cloud platform.

Assessment Criteria

  • 4.1

    Deploy a final version of the full-stack application code to a cloud-based hosting platform (e.g. Heroku) and test to ensure it matches the development version.

  • 4.2

    Ensure that final deployed code is free of commented out code and has no broken internal links.

  • 4.3

    Document the deployment process in a README file that also explains the application’s purpose and the value that it provides to its users.

5.

Identify and apply security features.

Assessment Criteria

  • 5.1

    Use Git & GitHub for version control of a Full Stack web application up to deployment, using commit messages to document the development process.

  • 5.2

    Commit final code that is free of any passwords or secret keys, to the repository and to the hosting platform.

  • 5.3

    Use environment variables, or files that are in gitignore, to hide all secret keys.

  • 5.4

    Ensure that DEBUG mode is turned off in production versions.
