Assignment 2 – Dynamic review site Introduction Task Description

This is an individual assignment in which you will explore the use of data interchange between web servers and browsers, dynamic construction of page content, and API design, using PHP, JavaScript, XML, and JSON. You may adapt the application to the review of anything you wish, but you should keep the basic schema the same.

The assignment tasks are closely associated with the lab work of topics 7 to 10. Code and examples from lectures and labs should be a useful guide throughout this assignment. The assignment requires a number of files and a report to be produced.

Initial Task: Create the database using your MySQL skills. You will need at least 4 raccoons, with at least 2 reviews each. Invent your own data. Use appropriate data types. Submit your SQL file as part of your assignment.

Mark up the complete data using XML tags and save it as an .xml file. Check that the file is well-formed and report the method used. Similarly, mark up the complete data using JSON and save it as a .json file. Check that it is valid JSON and report the method used to validate. Submit both files as part of your assignment.

Create a RESTful XML or JSON API, implementing, at minimum, the following functionality: list all raccoons, retrieve all details for a single raccoon, create a new review/rating, delete a review/rating, and update an existing review/rating. Follow HATEOAS practices.

Create an HTML/CSS/JS page that uses JavaScript, the DOM, and your back-end API to display a menu of all raccoons, display an individual raccoon’s details, allow user to submit a new review, and periodically poll the details for the current raccoon.

For ITECH6224 students: Identify four relevant resources on the topic of “Session hijacking and session fixation” and write an essay discussing the topic in your own words.

Report contents: The theme of the review site, statement of completion, DOM diagram, and essay task (ITECH6224 only). Give details of any assistance received.

All files should be zipped and uploaded to Moodle by the due date and time.

Paper For Above Instructions

The dynamic review website, inspired by the concept of connecting raccoon enthusiasts, serves as an engaging platform for users to share their experiences and ratings of various raccoon species. This project not only emphasizes the interaction between front-end and back-end technologies but also showcases the necessity of well-structured databases for efficient data management. This paper outlines the implementation steps required, from database creation to API functionality and front-end development.

Database Creation

To create the database "Raccoon Reviews," the first step involves utilizing MySQL to establish two tables: Raccoon and Review. The Raccoon table consists of three fields: id (primary key), name, and image_url. The Review table includes the fields: id (primary key), raccoon_id (foreign key referencing Raccoon), reviewer_name, review (TEXT), and rating (integer from 1 to 5). For normalization, an additional table for reviewers could be created if necessary but is not required for this basic schema.

Example SQL statements to create these tables are as follows:

CREATE TABLE Raccoon (


id INT AUTO_INCREMENT PRIMARY KEY,


name VARCHAR(255) NOT NULL,


image_url VARCHAR(255) NOT NULL


);


CREATE TABLE Review (


id INT AUTO_INCREMENT PRIMARY KEY,


raccoon_id INT,


reviewer_name VARCHAR(255) NOT NULL,


review TEXT NOT NULL,


rating INT CHECK (rating BETWEEN 1 AND 5),


FOREIGN KEY (raccoon_id) REFERENCES Raccoon(id)


);

In this implementation, at least four raccoons should be inserted into the Raccoon table, and each should have at least two corresponding reviews in the Review table. Data may be invented, such as naming raccoons after family members or favorite fictional characters, to enhance engagement.

XML and JSON Markup

Once the database is populated with data, the next task is to create XML and JSON files containing complete data marked up according to their respective formats. The XML file should adhere to standard XML syntax to ensure it is well-formed. An example structure might look like this:





Bandit


http://example.com/bandit.jpg






John Doe


Amazing raccoon!


5

For JSON, the structure can be represented as follows:

{


"raccoons": [


{


"id": 1,


"name": "Bandit",


"image_url": "http://example.com/bandit.jpg",


"reviews": [


{


"reviewer_name": "John Doe",


"review": "Amazing raccoon!",


"rating": 5


}


]


}


]


}

Both markup files should be verified for validity using appropriate validators and checked for well-formedness before submission.

Back-end API Development

The API can be created using PHP, ensuring it follows RESTful principles. The API should provide endpoints to meet the functional requirements detailed earlier, allowing for operations like retrieving raccoon lists, adding reviews, and updating records.

Example endpoint actions:

  • GET /api/raccoons: Retrieved list of raccoons.
  • GET /api/raccoons/{id}: Retrieve details and reviews for a specific raccoon.
  • POST /api/raccoons/{id}/reviews: Submit a new review for a specific raccoon.
  • DELETE /api/reviews/{id}: Delete an existing review.
  • PUT /api/reviews/{id}: Update an existing review.

Implementing HATEOAS involves including links to relevant actions within the response to each API request, enhancing usability and navigability.

Front-end Development

The front-end will utilize HTML, CSS, and JavaScript to create an engaging UI allowing users to interact with the API without refreshing the page. A navigation menu will display a list of raccoons, sortable by name or average rating. Upon selecting a raccoon, detailed information including the image and reviews can be shown, with options to submit new reviews dynamically updating the displayed information to reflect the latest input.

Furthermore, the application should employ a polling mechanism, fetching updated review data every 30 seconds to ensure users see the most current reviews, enhancing the user experience and engagement.

Session Hijacking Discussion (ITECH6224 Only)

For ITECH6224 students, an essay should be written exploring the implications of session hijacking and session fixation within the context of web security. Separately sourced academic resources should be cited to provide a well-rounded view of the subject, ensuring that the essay reflects an understanding of both ethical and practical dimensions of web development.
