SOLVED BY A TUTOR- Southern New Hampshire University Uses of the SQL & Mongo Databases Paper


  • Apply database systems concepts and principles in the development of a client/server application
  • Develop client-side code that interfaces with databases


You work for Global Rain, a software engineering company that  specializes in custom software design and development. Your team has  been assigned to work on a project for an innovative international  rescue-animal training company, Grazioso Salvare. You have been made the  lead developer on this project.

As part of its work, Grazioso Salvare identifies dogs that are good  candidates for search-and-rescue training. When trained, these dogs are  able to find and help to rescue humans or other animals, often in  life-threatening conditions. To help identify dogs for training,  Grazioso Salvare has reached an agreement with a non-profit agency that  operates five animal shelters in the region around Austin, Texas. This  non-profit agency will provide Grazioso Salvare with data from their  shelters.

In meeting with the client, you have discovered that they look for  certain profiles in dogs to train. For example, search-and-rescue  training is generally more effective for dogs that are no more than two  years old. Additionally, different breeds of dogs are proficient at  different types of rescue, such as water rescue, mountain or wilderness  rescue, locating humans after a disaster, or finding a specific human by  tracking their scent.

Grazioso Salvare is seeking a software application that can work with  existing data from the animal shelters to identify and categorize  available dogs. Global Rain has contracted for a full stack development  of this application, including a database and a client-facing web  application dashboard through which users at Grazioso Salvare will  access the database.

In the initial phases of this development, you developed a database  and a Python module enabling CRUD functionality for MongoDB. For Project  Two, you will complete the development of this project by coding the  dashboard and the database interface logic. This will include dashboard  attributes. The dashboard must be a user-friendly, intuitive interface  that will reduce user errors and training time.

Additionally, Grazioso Salvare has requested that the code for this  project be open source and accessible on GitHub, so that it may be used  and adapted by similar organizations. To that end, they have asked that  you also create a README file that documents and provides instructions  for reproducing the project.


Web Application Dashboard (Python Code)
After  successful completion of previous milestones and Project One, you have  created a database and established successful CRUD routines in Python  for MongoDB. For Project Two, you will now create a fully functional  MongoDB dashboard. This will allow the client, Grazioso Salvare, to  interact with and visualize the database.

To create the dashboard, you will create the different components in  Python code. Dashboard web applications lend well to the MVC design  pattern. Using this design pattern, the model is contained and accessed  in MongoDB, the views are dashboard widgets, and the controller uses  your CRUD Python module for queries as part of the interaction between  components. You will also be required to test and deploy the dashboard,  taking screenshots to show that each of the components executes  successfully.

The graphic gives a more visual depiction of the steps for the project. Step 1: Review the specs. Your code will put these into action! Step 2: Get started on the dashboard with an unfiltered data table of shelter animals. Step 3: Develop queries that allow users to filter the database. Step 4: Build interactive options through which users will activate the filters. Step 5: Add widgets for dynamic presentations of retrieved data. Step 6: Test the dashboard, verifying functionality with screen captures. Step 7: Create a README file to document your work.

  1. Before developing the Python code for the dashboard, be sure to  review the Dashboard Specifications Document provided by the UI/UX  developer at Global Rain. This document is located in the Supporting  Materials section and will provide you with examples of the different  dashboard widgets you will create: 
    • Interactive options to filter the Austin Animal Center Outcomes data set
    • A data table which dynamically responds to the filtering options
    • A geolocation chart and a second chart of your choice that dynamically respond to the filtering options
    • In addition to the widgets, you have been asked to include the Grazioso Salvare logo and a unique identifier  containing your name somewhere on the dashboard. A high-resolution copy  of the logo is included in the Supporting Materials section.
  2. Next, you will begin developing the Python code for your dashboard.  Starter code is contained in the ProjectTwoDashboard.ipynb file, linked  in the What to Submit section. Start by creating a data table on the dashboard which shows an unfiltered view of the Austin Animal Center Outcomes data set. To populate the data onto your table, utilize your previous CRUD Python module from Project One to run a “retrieve all” query and bring in the data from MongoDB.

    Tip:  Be sure to consider your client when creating the interactive data  table. Consider optional features that will make the table easier to  use, such as limiting the number of rows displayed, enabling pagination  (advanced), enabling sorting, and so on.

    Note: If you completed  the Module Six Milestone, you have already completed this step. Copy  your code for the data table into the ProjectTwoDashboard.ipynb file.

  3. Next, you will make sure that the dashboard filter options can properly retrieve data from the database. Start by developing database queries that match the required filter functionality.  Refer to the Rescue Type and Preferred Dog Breeds Table, located in the  Dashboard Specifications Document, to help you construct these queries.  

    Note: Be sure to utilize your previous CRUD Python module  (a PY file) from Project One to develop these database queries. You  will need to hard code in the username/password for the “aacuser”  account as part of the CRUD Python module class instantiation.

  4. You must develop the controller pieces to create interactive options that allow for the selection of data based on your filtering functions  (such as radio items or drop-downs). Develop these pieces in your IPYNB  file, and be sure to import and use your CRUD Python module queries  from Step 3. These interactive options will enable the control of other dashboard widgets, such as the data table and charts.

    Tip:  You may choose any interactive option that you wish, such as radio  items, a drop-down menu, and so on, as long as the client is able to  intuitively use the interactive option to filter the data. Refer to the  Dash Core Components reading from the module resources to help you set  up these options.

  5. Next, you must modify or create the dashboard widgets that receive  input from the interactive options and present those dynamic updates to  the client. Be sure to modify or create these widgets in your IPYNB  file. Specifically, you must do the following: 
    • Modify the data table you created in Step 2 so that it is an interactive data table that responds to input from the interactive options.
    • Create charts that display data in response to updates  from the data table. As outlined in the Dashboard Specifications  Document, you are required to create, at minimum, a geolocation chart  and a second chart of your choice.
    • Note: If you completed the Module Six Milestone, you have already  begun work on this step by creating the geolocation chart. Copy your  code into the ProjectTwoDashboard.ipynb file. You will need to make sure  that this chart receives updates from the interactive options.
  6. Finally, after developing all of your code, you must test and deploy  the dashboard to make sure that all of your components work. To  complete this step, run your IPYNB file. You must either take screenshots or create a screencast of your dashboard and widget functionality. Each of your screenshots or your screencast should contain the Grazioso Salvare logo and your unique identifier. Your screenshots or screencast must show the following: 
    • The starting state of your dashboard, which should include your widgets for the interactive options to filter data (such as radio items or drop-downs), the interactive data table, and the charts
    • Executions of your dashboard, showing the widgets after each of the following data filters has been applied (four screenshots total): 
      • Water Rescue
      • Mountain or Wilderness Rescue
      • Disaster or Individual Tracking
      • Reset (returns all widgets to their original, unfiltered state)
    • You will include all of these screenshots, or your screencast, in  your README file when describing the functionality of your project.  These screenshots are required as they demonstrate proof of your dashboard’s functionality.

Grazioso Salvare has requested  documentation to accompany the code for your dashboard. This will ensure  that they are able to understand the work that was completed and more  easily maintain the code for this project.

You have been asked to create a README file that documents the project and includes instructions for reproducing the project. Be sure to address all of the following areas:

  • Describe the required functionality of the project.  Include the screenshots or screencast taken while testing and deploying  your dashboard (Step 6) as proof that you have achieved the required  functionality.
  • Describe the tools used to achieve this functionality and a rationale for why these tools were used. 
    • Be sure to explain why MongoDB was used as the model component of  the development, including what specific qualities or capabilities it  provides for interfacing with Python.
    • Be sure to explain the Dash framework that provides the view and controller structure for the web application.
    • Be sure to include links to any resources or software applications that were accessed or used.
  • Explain the steps that were taken to complete the project.
  • Identify any challenges that were encountered and explain how those challenges were overcome.
