Introduction to Web Services And how to use them in your apps Konstantinos Goutsos Undergraduate student – ECE Department StudentGuru Patras Member 

What’s a Web Service? Most web applications use a Database to store their data and a Front-End to present it. The Web Service connects the Front-End to the Database enabling it to access stored data. 

Why are Web Services useful? Using an extra layer as a way to provide data to your app reduces complexity and improves maintainability Separating data from the front-end makes it easier to work with a team When done right, services are accessible from any platform as they are based on open standards 

Where have I used services?  Dynamic websites  Most mobile apps  Multiplayer games  Application Interfaces (APIs)  And every other application using dynamic content 

Demo outline We will add scoreboard support to the “Find the Number” app following these steps:  Create a database to store our data  Create a WCF Service to get/send data from our database  Use the service to connect the application to the database
