What is a Web Service?
Try to understand the below examples: You are in a restaurant. How your orders are communicated with the Chef? The waiter is responsible for this right. So, here the waiter acts as a web service that makes sure that 2 systems communicate (here you and chef) Another example, planning for a trip. Want to book tickets? Mostly, we will go to the MakeMyTrip app. We get a list of all the airlines and we compare the prices. Ever wondered how MMT has all the data. See, no airline will allow a third party to search in their website. Another possibility might be that what if the airline is dumping data to MMT, but what if the status changed dynamically. This creates a risk. All these airlines have exposed their web services through an API. MMT uses those web services to communicate. Web Service - Service available over the web. - Applications communicate over the web. - Database independent like in the above example different companies may be using different databases...
