Hi Priyanka,  
This is not so much a question about elasticsearch but more about whichever system you use to feed it.  
Logstash is one example of an ETL tool and [here](https://discuss.elastic.co/t/loading-incremental-data-into-elasticsearch-from-oracle-database/102007/3) is an example question about using it to do incremental updates from a database.  
If you have further questions it's probably best to ask in the Logstash forum
