- - - - These will be styled based on the nature of the message eg: (green - success, red - warning)
    - - Navigation elements will be consistent throughout the solution meaning that a user can easily navigate the solution regardless of what page they are on
  - - - Assists with the solution's learnability
    - - It will also be ensured that this order of 'tabindex' is logical, and flows consistently throughout all pages
    - - This ensures that the simplicity of the interface doesn't interfere with the usability and helpfulness of the solution
    - - This widens the demographic that can use the solution
  - - - Alert banners will be implemented at the bottom of the page to notify users of ongoing processes
        
        These are colour-coded, ensuring that the overall message is easily portrayed through the interface design
      - Inputs will be cleaned and checked before use, ensuring that a user's inputs are accurate and relevant to the process
      - It will be ensured that the solution focuses on error-prevention in that it will be difficult for a user to make a mistake
      - Solution's interface will be minimalistic, maximising the range of features available whilst also ensuring that the interface isn't cluttered
    - - The interface layout of the solution will be consistent with the layout used in the Terrace website
        
        Ensures that the interface is similar to users that are already familiar with the Terrace website
      - Site layout will be consistent throughout all pages. Elements used in the interface will be mirrored throughout it, ensuring that the site feels 'connected' and 'linked'
      - Consistent page styling will be used
    - - Elements will adjust based on the size of the viewport
      - Solution must be usable on mobile devices (seen in technical proposal)
      - Solution can be operated on multiple different platforms
    - - Further explored on in the hardware/devices branches
      - Navigation elements will be dynamically adjusted depending on the size of the current viewport
        
        When the viewport is decreased, the navigation bar will transform into a hamburger menu
      - The Bootstrap 4 framework will be used to develop a mobile-first front-end. This framework simplifies web responsiveness
        
        The layout of the solution on a mobile viewport is considered before the development of the larger viewport layout
        
        Dynamically adjusts the sizing of images, text, columns, rows etc.
- - - - Extension of HTTP
      - Important when users transmit sensitive data
      - Websites that don't use HTTPS are marked differently than those that do use it
      - Prevents websites from having their information broadcast in a way that's easily viewed by anyone snooping on the network
    - - Adds a layer of security that helps to detect and mitigate certain types of attacks, including cross-site scripting and data injection attacks
      - Response header that allows web site admins to control resources the user agent is allowed to load for a given page.
    - - Encryption is simply a security method where information is encoded and can only be accessed or decrypted by a user with the correct encryption key.
        
        Symmetric Encryption
        
        Uses a secret key which is applied to the content to change it in a particular way.
        
        Sender and receiver must know the secret key in order to unlock the information. This poses a risk to the information if someone has access to the key when they shouldn't.
        
        Asymmetric Encryption
        
        With asymmetric encryption, two related keys are used (key-pair). One of the keys is available to the public so you can encrypt the data. Then there is another key which is then kept secret
        
        Slower than symmetric encryption; however, you don't have to worry about passing public keys over the internet.
    - - Appends a random 'salt' as a prefix or suffix to the password before it is hashed
      - Ensures that although two passwords may have the same hash, their hashed value when a salt is appended is different
      - Transforms the password into something that is 'non-deterministic'
      - Fixed-length cryptographically strong random value
      - Can mitigate the damage that a rainbow table or dictionary attack could do
      - This 'salt' is a value that is stored in the same table as the password hash
      - This salt is generated upon the creation of each stored credential rather than per user or system-wide.
    - - This is essential as mentors are required to upload an image of their blue card when they register for the solution
      - The file extension of the image needs to be checked; however, this can be bypassed through the use of a double file extension
    - - Ensures that the input is valid
      - Validation checks ensures that the type, length and format for the input is acceptable
      - Adds a layer of protection against injection as inputs are cleansed of any special characters
    - - Passwords aren't stored as their original value. Once a user submits a password, it will be hashed.
      - Using SHA-256, inputted passwords are transformed into a 256-bit hash value that is usually represented as a hexadecimal number of 64 digits.
  - - - Used to temporarily store a user's information
      - Student's information can be used to personalise various aspects of the system
      - Reduces the amount of table querying
  - - - Students can view sessions that they are signed up to attend
      - They can rate the mentor once their session is complete
      - Can propose sessions that require a mentor to facilitate
      - Can cancel a session for another time that may suit them
      - Add/remove subjects that they need help in
    - - Can approve pending mentor applications by looking at the uploaded image of their blue card
      - Can manipulate all aspects of the data
      - Can create sessions for individual students if need be or can simply create sessions for a common need
      - Can change the details of a session
      - Can generate reports on each student given their attendance and session notes
      - Can view ratings for each mentor and student
    - - Can arrange a session for a student
      - Can edit session information if need be
      - Can rate a students performance with a rating and give them an annotation
      - Can mark a student away or present
      - Can fill in an empty session that a student has made
      - Can add/remove subjects from their list of preferred subjects
  - - - This integration with TASS allows for student data to be secure and always up to date (data is already authenticated)
- - - - Collection of general student information for year 11 and 12 digital solutions students
      - This is used as sample data to mockup a solution that would be applicable for a much larger number of students
      - In the final solution, the solution would be integrated with TASS, allowing for data to be constantly up to date and secure
      - Student information is also used for student account creation and account verification via email
  - - - Contains each individual session as an entry into the table
      - Contains the date of the session including start and end times
      - Extra session info -> (mentor, student limit, subject, etc.)
    - - Table that contains all user information for students, mentors and admins.
      - This table could be linked to a further two tables (students, mentors). This would remove the possible NULL fields in the users table. The information that is common to all users (username, password, etc.) will then be stored in the users table
    - - This is a list of subjects that is available to the students and mentors.
      - Simply a list with a subject id, subject name and a year level.
        
        Year level column is important as various mentors may only be able to assist students up to a certain level for some subjects
    - - Enables a user to add their 'preferred' subjects
      - Functionality
        
        Mentor adds subjects that they are able to mentor
        
        A student opts in to subjects that they need help with
    - - Allocates a student to a session
      - Records a student id linked to a session id
      - Contains extra information regarding the student in relation to the session (attendance, notes, status etc.)
