API (Application Programming Interface) is a way for an information system to communicate with other systems. It works similarly to a browser request of a webpage, but instead of the webpage a server returns a formatted data.

For example, if your system needs to know the current weather conditions, you can retrieve this information from a weather API. OpenWeatherMap is an example of a weather API (

https://openweathermap.org/current

). This API supports different parameters to specify the data you request.

A request like this one  will return a current weather condition for the given ZIP in JSON format. You can test it in your browser. Appid parameter serves to control who is accessing the data (the ID in the given example is used for test purposes). You may also read the API docs for this API to get an idea about the structure of the data and the list of acceptable parameters.

Directions

Based on the topic of Course Project, find a relevant public API and submit the following information about it:

  • A short and concise summary on how this API will benefit the system proposed in the project.
  • A sample request to this API; download the result of the request and provide either a visual or statistical summary of the data.
  • Submit you work within a APA 7th Edition formatted word document.
  • For example, if you use an API that returns a list of geographical coordinates, you may import them to Google Map (

    https://www.google.com/earth/outreach/learn/visualize-your-data-on-a-custom-map-using-google-my-maps/

    ).

    If you are familiar with Excel or other statistical software, you can produce either a meaningful chart or a simple statistical analysis of the data. For example, if your data consist weather information for 30 days, you can compute an average weather, or draw a chart of the weather for that period.

    Most likely, you will need to convert a JSON data into CVS (or Excel) you can always use tools like this JSON Convertor (

    https://data.page/json/csv

    ). Note that not every object can be converted into a meaningful spreadsheet. Most likely you will want to have a list [] on the top level of the JSON structure, in order for each of its elements to be converted to a row.

    COURSE PROJECT OVERVIEW
    The course project consists of a series of interconnected weekly assignments that culminates in a final
    project submission (Unit 7) and a presentation (Unit 8). Students will use the business case scenario
    below to complete the project and follow the deliverable schedule included at the end of this document.
    BUSINESS CASE
    A healthy lifestyle advocacy group is aiming to build a bike sharing system within a medium size
    metropolitan area. The group has signed a contract with a company to provide the bike sharing
    technology and hardware (bike stations, bikes, network equipment, a server, and bike sharing software
    that automates the process of checking out and returning bicycles, and billing customers).
    DOCKING STATIONS & BIKES
    Image source
    The docking station provides a limited number of bike parking spots, and is characterized by its location,
    bike capacity, and by real time number of bikes parked. Docking stations have computers running on
    them, credit card reader, and a networking module which allows it to be connected to the Internet. The
    fleet of bikes has also been purchased.
    FUNCTIONING OF THE SYSTEM
    There are two ways a user can get access to the system:
    1) Using her annual subscription ($70)
    2) Buying day pass ($5)
    Every ride under 30 minutes is free. User is charged $1 dollar for a ride between 30 and 1 hour, 3 dollars
    for rides between 1 hour and 2 hours and a flat rate of 7 dollars for any ride over 2 hours. The users who
    haven’t returned a bike within 10 hours are billed with a $50 fine.
    REGISTRATION PROCESS
    A user can register online or purchase a day pass at the station.

    SCHEDULE
    Unit
    Title
    Introduction
    Description
    Points
    Unit 1
    The summary of
    the business
    processes with the
    rationale for the
    new system
    development
    The advocacy group as hired an IS
    developer company to develop an
    information system to support
    operations of the bike sharing system.
    Submit a two-page summary with the
    description of each business process, which will
    include:
    40
    The description of
    the IS architecture,
    the list of the
    software and
    database
    components, and
    hardware
    architecture
    The IS designed for the case should
    connect docking stations, manage user
    registrations and billing. We learned
    about different architecture models (e.g.
    centralized, distributed, and cloud).
    Unit 2
    See the business case for detailed
    description. First the developer company
    analyzed operational business processes
    of the bike sharing systems (bike renting,
    user management and billing) to produce
    a summary of those processes, and
    describe how the information system will
    be able to automate them.
    1) brief description of what or who (hardware
    or user) will initiate it;
    2) what the process should do.
    3) Explain what would be the role of the
    information system to support this process.
    In a Word document:
    40
    1. Propose the IS architecture for the IS for
    the bike sharing system. Explain the
    rationale behind the choice (between
    half of a page and a page);
    2. list all the software, and database, and
    hardware components;
    3. draw a architecture of the system
    showing the components using Word
    shapes, use arrows to show business
    process and major data flow between
    2
    them.
    Unit 3
    Security risks
    summary
    Any IS functions under security risks.
    These risks are especially critical when a
    system is distributed and connected to
    public networks.
    Provide a one page security risks summary for
    proposed IS which should include:
    40
    1. main security risks and the potential
    consequences;
    2. methods or design strategies to
    minimize each of those risks.
    Recommend a brief (one paragraph) structure
    of information security management that would
    include personnel roles with their core duties to
    manage information security.
    Unit 4
    Designing and
    implementing the
    software
    component
    Designing and coding the entire software
    system for the given case is a complex
    task. For this project, you will be asked to
    design and implement a small
    component of the information system
    functionality.
    Submit a Word document that would include:
    40
    1) Flow chart of the billing schema after
    completion of the ride, which will
    include including the subscription status
    check, and the price policy provided in
    the case description.
    2) Assuming that subscription_status == 1
    is an annual subscriber and
    subscription_status == 2 is a daily
    subscriber for the day stored in the
    variable day_subscribed and the current
    day stored in a variable now,
    pickup_time and drop_off_time are the
    times in minutes, write a Python code
    to describe subscription check and the
    3
    price calculation for a single ride.
    Unit 5
    Business data
    architecture / data
    models
    Any IS system operates with data. Data
    can have different types
    Design data structures (variables, lists, objects)
    that will describe the registration and billing
    processes.
    40
    Submit a Word document with the data
    structures IS will need to have in order to
    support those processes. For example, one of
    the structures should describe a list of
    registered users with their statuses and other
    parameters that you will find important.
    Unit 6
    Unit 7
    Design of the
    relational database
    structure
    Data in IS can be stored in the database.
    Relational databases are the most
    commonly used type of databases.
    In a Word document:
    Development and
    implementation
    plan
    In this unit, you will finalize your course
    project by creating a development and
    implementation plan.
    Final submission:
    40
    1) create a table(s) to describe current and
    historical rides;
    2) write SQL statements that would allow:
    a. to compute the average ride
    duration for a given user;
    b. number of bikes check out at
    the given bike station;
    c. retrieve the list of all currently
    active users.
    60
    Create a development and implementation plan
    by gathering key information from each of the
    project components you developed this term
    and summarizing it in the format outlined
    4
    below. Note that you should incorporate faculty
    feedback when developing your plan.
    Submit a 1-2 page plan describing your system
    and the development and implementation steps
    that the company will need to take to in order
    to successfully complete the project. Your
    summary should include the following
    elements:
