IA2 (Client Problem (Requirements (Reduce tuckshop lines by allowing…

- - - - When you enter the app it immediately asks for your suburb and saves your most recent location for future uses. This relates to the given task as this could be applied through a campus selector to find the nearest tuck shop.
      - Shows a informative images of what the food is when browsing
      - Gives a score out of six and shows the amount of users that have voted on it. If you click on it, it also shows written reviews and score distribution
      - Only shows the a brief description of the item with its price, however, no other information is shown immediately
      - Shows possibilities for meals, e.g. if the user is viewing a burger the app recommends a meal to accompany it
      - Each store has a different layout of information and gives the user an inconsistent experience
    - - Shows a meaningful image of the item that is being sold
      - Shows the price of the food as well as a rating given by other students on how good it is
      - Shows dietary information about the item when the user presses on the item image, such as kJ, halal, peanuts, dairy, vegetarian friendly
      - Shows all items in a easy to view way and displays that items are still available by keeping them in full colour, and shows unavailable items in greyscale
      - Allows the user to filter through options to find items that meet their needs e.g. if they are vegan or halal.
      - Shows a consistent colour scheme of black, white and green which makes the app pleasant to view and remain consistent
- - - - A potential social impact of this app in the context of a broader school community is that it will be able to allow students to spend more of their lunches relaxing. Studies have shown that students perform better when well rested and fed and as such if they are able to quickly and easily get their lunch without waiting in lines they will be better fed and better rested for their next classes, improving their performance
    - - An economic impact of this app for the school is that it the ease of access and ability to purchase will increase and as such will drive more students to buy from the tuckshop. This will increase the revenue produced by the tuckshop and subsequently the school. Allowing for more money to be put into the education of students
    - - A personal impact of this app is that, similar to the wider social impact of the app, will allow for students to be able to spend more of their lunch times resting. This will allow for them to perform better in their later classes and as such improve their overall grades in school.
- - - - Tuckshop Menu Screen:
        
        The menu screen will have a large table view that shows all the different items that are able to be bought at the tuckshop. Each table view cell will have the name, an image, whether its halal and vegetarian friendly, price and size. This will allow the user to make an effective decision quickly about what they would like to have. It also allows vegetarian and Muslim users the ability to quickly identify items that they are able to have
      - Order History Screen:
        
        The order history screen will show the user previous orders they have made. This will be displayed in a table view to allow for infinite theoretical past orders to be shown to the user. Each table view cell will have an image, the name and the price of the item. It will also have a button that will allow the user to order the selected previous order again allowing for quick ordering if the user has the same thing often
      - Profile Screen:
        
        The profile screen will show the user all the personal information that is associated with the account.

      - Home Screen:
        
        The home screen will act as a hub for all other major functions of the app, having buttons that connect to all the other features of the app such as the menu screen, settings, profile, and current order screen. This screen will also be accessible from every other screen through a 'return to home' button.
      - Login Screen:
        
        The login screen will be the first screen the user accesses and will have the app name and the username and password section.

A small hint box will be located underneath the username and password field instructing the user as to what their username should look like
      - Order Confirmation Screen:
        
        The order confirmation screen will display all the items the user has selected to purchase in a table view. A purchase button will be at the centre middle of the screen that will allow for the user to purchase the order. A UI alert will pop up once the user has pressed purchase to confirm that they would like to purchase it, if they press yes than another alert will tell them that their order has been placed and tell them their new wallet balance
    - - All interactable features of the app will be clearly distinguished from the background with a unique colour as to allow for the user to easily define buttons and text fields as interactable
      - A consistent and minimalistic colour scheme will be used throughout the app to make it more accessible as it will not overload the user with information and will be aesthetically pleasing to users
      - The users personal information and information required to access their ‘wallet’ will be encrypted and authorised before allowing a user to access their account. Measures will be taken against cyber attacks focusing on stealing a users money
    - - Link colours must be different to other text colours and must have a colour contrast of at least 4.5:1
      - Main headings must have a colour contrast of at least 3:1
      - Verdana must be the primary font and secondary can be Helvetic, Ariel, and sans serif
      - An 'About us' and 'Help' screen must be accessible from the home page and must meet set requirements

    - - Sub-heading must have a meaningful hierarchy
      - Error messages must be clear and specific and give clear details on how the user can fix the issue
      - Interactive text fields/forms must have a visible label to show allow interaction
  - - - SQLite3 will be used to create and manage the database in this task.
      - The database will be able to modified through an admin login for the app so as that it can be updated if prices and other information about items is added or removed
      - The Xcode development environment will be used to create this app for the latest IOS and ideally an iPhone as most people have access to an iPhone and it is more practical than an iPad for ordering food on the go
      - The database will be created as a relational schema so as that multiple tables can be created at connected through primary and foreign keys so as that it can be more effectively normalised
    - - Random Meal Generator
        
        The random meal generator will generate a random meal by first creating 3 random integers. These will be used to select a main meal, snack and drink from the Menu table in the tuckshop database. The total price and other options about the food will also be able to be changed by the user. This will be impleneted by using a WHILE statement and a 'brute force' method and generating meals until they meet the users requirements
      - Read and Retrieve values from Database
        
        In order to read values from the database SQL queries will be used. This will achieved with the WHERE function that will allow the user to query the database where the users search is equal to a specified record. The records retrieved will than be converted to swift readable variables and displayed
      - Order History
        
        The order history process will be made by storing all previous order ID's from the users previous orders. These will be stored in a separate table in the database through the use of the APPEND function. These will than be retrieved from the database through the WHERE function as the user will be shown all previous orders associated with their userID
      - Ordering
        
        The user will be able to press an 'add to cart' button that will add the item they have selected to their cart. This will be done by appending the menuID of the selected item and appending it to the orderHistory table with the corresponding orderID
      - Menu Display
        
        The menu will be displayed on a table view, this will allow for the user to scroll and see all information about each item. The data will be retrieved from the database through the SELECT * FROM function as it is collecting every menu item from the menu table as well as all information associated with each item to display
    - - Database
        
        Modifications
        
        In order to normalise the data to allow for it to be used effectively in a database several things must be done including; creating seperate columns for the sizes of meals and drinks as they can be several different data types, putting the extra information of a the item on a different table to the description and price of the item, these being halal, allergy and veg info.
        
        The data will be normalised using the three normal forms. This will allow the data to be formed into a relational schema database and be used in the project.
      - Datasets
        
        Menu.csv
        
        The dataset given provides a list of menu items with a MenuID, Category, Desc, Price, Halal, Allergy info, and Veg columns. This gives enough information to create a detailed description of a food item to the user before they buy it.
        
        Additional information that will be gathered to add to the dataset is images of the food/drinks. This will help the user to understand what they are purchasing.
        
        Additional information that will be gathered to add to the dataset will be information about students including their: student ID, family name, given name, wallet amount, and email. This will allow for the student to login to their school account and access their school wallet balance.
