Terrace Uniform Shop - Coggle Diagram

- - - - System status being visible
        
        The user should always be informed on where they are in the website and what they are doing. This is done through clear descriptions and appropriate feedback.
        
        For example, if the user clicks on a button in the header they expect to be transported to another page in appropriate time and therefore good interface design is doing so.
      - Having the interface and the real world be interlinked
        
        The system should use words and phrases the user is familiar with rather than system specific language and conventions
        
        For example, if an interface asked the user to input their password a description next to the text box should use the word 'Password' as this is the well known phrase for the type of input required.
      - The user having a sense of both control and freedom
        
        The user should have an emergency exit to leave pages and functions.
        
        For example, a redo and undo function should be supported
      - Interfaces have a consistent style and standard
        
        Actions or functions instigated by the user should result in the same outcome throughout the different pages within an interface.
        
        For example, the buttons within the header should always lead to the same pages when they are pushed.
      - Eliminating error messages from the system
        
        Test the interface thoroughly for errors to ensure that the user does not encounter error messages
        
        For example, if a process commonly results in an error message then the code should either be worked on and then tested or deleted from the interface all together.
      - Ask the user to recognise information rather than recall information
        
        The system should not ask the user to remember information that is not present on the current interface. Instead, the interface should present the information to the user and ask them to recognise that piece of information
        
        For example, if a user is purchasing an item the picture of the item should be present on the checkout page so that the user does not have to remember what the item they are buying is
      - A minimalist design should be used within each interface
        
        Every piece of dialogue and every element within the interface should be necessary as unnecessary information cognitively strains the user.
        
        For example, a description next to the submit button is not necessary as the user already knows what the button does and therefore should not be included.
      - Making sure users understand and diagnose error messages
        
        error messages should be presented in plain language
  - - - Only the password and username has to be entered and if they match fields in the database the user will be transferred to the last page they were on.
    - - Basic items such as email, password and their s-number and student password if they are a registered student
    - - The user will select a category of products through clicking on the image representing the category. Then, for consistency
    - - only the payment method has to be entered as transaction security is not required for this assignment
  - - - Once the user is logged in as a student, they can access the purchasing and browsing features
    - - If a user is logged in but not as a terrace student they have 20 days in which they can access the purchasing and browsing features. however, after the 30 day period the account will be restricted from purchasing items
    - - Users that are not logged in will not have access to the purchasing features in the shop but can browse through the items
        
        This is so that the terrace store does not run out of clothing for terrace students
    - - the organiser can add or remove items from the website by dropping them from the sql database. They can also add or delete accounts using this method
        
        The organiser is also provided with data regard to the units of each item sold per a period of time and other sales data
- - - - A short paragraph describing the purpose of the item
