Building Services with ASP.NET Web API
Services expose data and processes through APIs (Application Programming Interfaces) implemented using common approaches or standards. Decoupling our back-end from our front-end makes it possible for our services to support multiple client apps. We can even allow other developers and organizations to consume and use our services to further broaden the reach of our applications. In this course, you'll learn how to use the ASP.NET Web API framework to build a RESTful service or HTTP API. As you learn about Web API, you'll create a service for the Fitness Frog single-page web app (SPA) developed using Angular.

Integrating PHP with Databases
Building a PHP-driven page is the first step in mastering PHP. The true power of PHP shines when you connect it to a data source like an API or a Database. To introduce you to databases, we'll use an example project -- a Personal Media Library application. We'll refactor this project by replacing an associative array with a database to provide a more robust and scalable tool to store the data in the media library. In the process, you'll learn how to use PDO -- a PHP extension to communicate with a database. You'll also learn about relational databases including how to search for data across multiple tables, as well as how to add common web site features like search forms and pagination.

Object-Oriented PHP Basics
At a glance, object-oriented programming can appear to be far more complex than simple procedural, or inline, code. However, this doesn’t have to be the case. Because object-oriented programing is similar to the way human beings perceive the real world, using the object-oriented approach, can help you visualize the solution to a problem more easily. Object-oriented programming, or OOP for short, is a style of coding that allows developers to group similar tasks into containers. In PHP, containers are defined using classes. A class contains all the functions and variables that describe an object.

User Authentication With Express and Mongo
Learn how to implement a custom user authentication system that controls users access to web resources using Node.js using Express and MongoDB. The system lets users sign up, log in, and log out, limiting access to password-protected resources. Express is a popular web framework for creating MVC applications and RESTful APIs in Node.js. Express lets developers define routes and middleware for submitting and retrieving data in our database. We will leverage the document based NoSQL database, MongoDB, to store our user data by creating a user model with mongoose. Mongoose is an open source Node package for defining data models for an application and connecting to MongoDB.
