Advantages -:

Low touch -:

The administration enables you to center completely around esteem included application advancement, instead of burdensome and tedious database organization. Amazon SimpleDB consequently oversees framework provisioning, equipment and programming upkeep, replication and ordering of information things, and execution tuning. 

Exceptionally accessible -:

Adaptable -:

As your business changes or application advances, you can undoubtedly mirror these adjustments in Amazon SimpleDB without agonizing over breaking an unbending construction or expecting to refactor code – essentially add another credit to your Amazon SimpleDB informational index when required. You can likewise pick between predictable or in the end reliable read demands, picking up the adaptability to coordinate read execution (idleness and throughput) and consistency necessities to the requests of your application, or even divergent parts inside your application.

Connection With SimpleDB -:

     BasicAWSCredentials awsCreds = new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY);
		AmazonSimpleDBClientBuilder clientBuilder = AmazonSimpleDBClientBuilder.standard().withCredentials(new          AWSStaticCredentialsProvider(awsCreds)).withRegion(Regions);
		this.simpleDB = clientBuilder.build();
  

Used Query In SimpleDB -:

                String selectdata = "select count from " + DOMAIN_NAME;
                items.add(new ReplaceableAttribute(counter, "0", true));
		    SelectRequest data = new SelectRequest(selectData);
			List itemsData = simpleDB.select(data).getItems();
  

Create Record In SimpleDB -:

		List items = new ArrayList<>();
		items.add(new ReplaceableAttribute(cunter, "0", true));
		items.add(new ReplaceableAttribute(LAST_UPDATED_FIELD, new TimeProvider().timeNow().toString(), true));
		simpleDB.putAttributes(new PutAttributesRequest(DOMAIN, DomainName);
