SQL Database

  • Let us take a traditional database, here, a database design and Scheme are to be defined before you enter data. In data-lake, there is no format for this. It is like a dump. 
  • This dump you can send to Hadoop repository for data analysis. This repository can be incremental. Also, you can build a large database.

Data lake Vs Hadoop

Data-Lake is a dump of data with no format. There are many pre-formats required before it sends for analytics. One is data security and encryption. These techniques to be done before you send your data to Hadoop repository.

In real-time, Hadoop data analytics need lot other pre-processing of data required to proceed further.
