Task Creation Page
Design:
The form contains standard information that the dorm manager need to fill out when a resident moves in or moves out of the dorm. There are two main tasks including Move In and Move Out. The information on the page changes dynamically depending on the type of the task. This page will be visited very frequently by the user, so it's designed to be efficient for filling out information. The Useful information panel will contains auto-fill information that help the user speed up the filling out task. One of the important decision for this page is to fit the two panels into two scroll views without overflow the information to the whole page. The user can choose to scroll each panel separately without moving the whole window. It's because we want to user to make good use of the auto-fill function, so they can scroll the left panel up and down while keeping the right panel statically in the view port.

One of the importance decision that effect the design is the affordances of this right panel. Many users mentioned that there wasn't enough affordance to show the auto-fill function of the information on the right. Therefore, we have decided to put a place holder on the input where the auto-fill information supposed to fill in when the user hovers over those information. Figure 2 shows the result of the auto-fill functionality.

Another important feature is when the user submits the form, if there are some missing fields, the user will receive a pop up noticing them about these fields. The user can have the option to go back and fill out those missing fields or save the form any way. Figure 3 demonstrates this functionality.

In order to follow the CRUD model presented in class, we decided to let the user edit the task. The page will be pre-filled with the most recent updated information. Figure 4a and 4b demonstrates the edit task functionality of the website.

Implementation
The back end of this page is supported by Parse. There are three objects that currently present on the server: Resident, Task, and Room. Each of this object will have a reference to the other objects so that whenever one object changes, it will also change the other. After the user submitting the task to the server, a task object will be created with each attribute corresponding to a field in the form. Then, the room and the resident will also be updated on the server to reflect the task i.e if a resident Move In to a room, the room becomes occupied and remove from the available room and the resident gets added to the system.
For the updated task, we also have to make sure that we do not created duplicate object on the server since Parse doesn't automatically check for that.
Since there are three main pages sharing the same source of information, we need to make sure that changes on one page will be reflect on other pages too. For example, if a person move out, the main page will show that as a pending task and the floor plan also have to indicate that the room is now vacant. All of the information uploading to and downloading from the server are text-based, so the retrieving time is almost instantaneous which enable the user see the current update from the server at no time. In addition, to respect the anonymity of 6.813, we also use fake data for our database which introduce some inconsistency among information. However, this doesn't present any usability problem for the user.
