This document discusses creating mobile applications that connect to a SQL Server database through a web service API. It outlines the workflow of a web application with SQL Server, explaining how to create an API interface for mobile apps to access the same database. The key points are that an API allows sharing data and business logic changes across platforms, while JSON is commonly used for API-app communication. It recommends learning web services, JSON, and HTTP libraries before building mobile apps that connect to backend services and databases.

According to the query/request , SQL server will send the data back to the web server (Application) as a response. 4. And then we can arrange or perform operations on that data from the webserver.

- 8. When we need to build another application that also uses the same database and data like Android/iOS applications, we will have to build an interface between the new platform application and the existing web application., this interface is called API. It is not recommended to connect directly to the SQL server from iOS/Android because it will not be able to make a sudden change in business logic or data manipulation as the application is in clients device. If it is accessed through the web service then we can make changes to the web service at any point of time and it is a painless way for users too. SQL Server
- 9. In this case we can create API using web service in the web application , and we can access that web service from any other platforms/applications. The main thing we have to be careful about is the method that we are going to use for communication between the API and the application. As we are building the application in different language and different platform we need a common language/method of transferring data. That are JSON/XML methods. The most used method is JSON data., JSON is a method that wraps a data into an object with a key-value pair. And for most of the programming languages, libraries that supports JSON are available.
