In this Capstone project for the Photo Tourist you will implement a Ruby on Rails web application that makes use of both a relational and NoSQL database for the backend and expose the data through services to the Internet using Web services and a responsive user interface operating in a browser from a desktop and mobile device. You will have a chance to revisit and apply what you have learned in our previous courses to build and deploy a fully functional web application to the cloud accessible to your co-workers, future employers, friends, and family. In developing the Photo Tourist web application, you will get to work with different data types and data access scenarios (e.g., fielded data display and update, image upload/download, text search, access controlled information) to provide your users the ability to show off their photos and information from trips they have taken and to seek out photos and information from trips taken by others. Using the application you develop, your users will be able to • Create an account • Upload and download photos to the site and make them accessible to others • Provide descriptions of trips and photos that others can read • Organize photos by location and trip, • Find photos based on location • Find photos based on text searches of descriptions • Locate the place where the photo was taken on a map

From the lesson
Technical Architecture and API Development Setup
In this module, we will start your journey into being part of an end-to-end application development as a Rails/AngularJS fullstack developer intern. You will learn the technical architecture and software requirements of the targeted application you will be a part of developing. You will also get a chance to shake off any rust that may have accumulated on your Rails development skills.
As a part of the technical architecture, you will learn of the various layers, technologies, libraries, and services used in the development, deployment, and operation of the targeted application. You will get an early sense that this course is "no joke" when it comes to challenges, but you will be shown a path through most of them. You may be able to skip the application installation until the end if you are using the same computer that you used in the first five (5) courses of the specialization. None of the new software installations are required for this module -- but are included in a single lesson for modularity. You will develop an end-to-end, API-to-Database, resource solution for ActiveRecord/RDBMS and Mongoid/MongoDB using Rails scaffold generator. You will establish a Git repository for this work, provision database and Rails resources on the internet for staging and production deployments, and deploy your solution to the Heroku to be accessible from the Internet.
If you are a seasoned Rails developer and competent with ActiveRecord, Mongoid, and Heroku -- you may want to initially skip the review lectures, review the final Git commit for module one (1), and try your hand at the optional assignment at the end. Aside from the technical architecture lesson, this module is mostly a quick breeze through many of the topics of courses one (1) through three (3). A similar, small-scale review of courses four (4) through five (5) will be covered in the next module. Please enjoy! Also, if you have not done so already I recommend that you read the Course Overview description which provides additional context on what you will be doing in this course.
