Question

Which programming language can we use with NoSQL? Give me an example of a code? And what does it do?
please write the answer in the computer not from the paper

Answer 1

Hello,

TO answer your question, any programming language can be used with the NoSQL database. I will be considering MongoDB as the NoSQL database to be specific. My choice will be Java.

Why Java?

Java is the most popular language and is evidently present everywhere right from your mobile phones to the PC. java has got many inbuilt features that help it gain robustness such as JVM, JIT, etc. Also since java uses bytecodes to execute the program on any platform it is considered to be safe programming languages because also its is parser with the rigorous compiler check

How to use it?

At the very first you set up MongoDB server and create the DB on your local machine, followed by downloading the Java to MongoDb connectivity jar from the website

http://mongodb.github.io/mongo-java-driver/?_ga=1.157773946.175697985.1454146274

Next, you need to import the jar into your project workspace and then copy-paste the below program

////////////(MongoDbConnectionExample.java)////////

import com.mongodb.DB; import com.mongodb.MongoClient; public class MongoDbConnectionExample{ public static void main( String args[] ){ try{ MongoClient mongoClient = new MongoClient("localhost", PORT_NUMBER(example-1234)); DB db = mongoClient.getDB( "YOUR DB" ); System.out.println("Connection established"); } catch(Exception e){ System.err.println( e.getMessage() ); } } }

What does it do?

It tries and connects to the your local Mongo DB server. If your connection is successful you get the message(Connection established) else you get the proper error your code is facing in order to connect it to the database.-
