   • If we talk about the dataset or the database, it might hold your most recent purchase history, but indirectly it helps to analyze current shopper trends. 

   Let’s see five key differentiation of Data Lake and Data Warehouse:

   1. Information in a local organization 

   Gathered data can be arranged quicker and gotten faster since it doesn’t have to experience an underlying change process. 

   For customary social databases, the information would need to process and controlled before being put away.

   Outline on-Read, then again, permits the pattern to be created and custom-fitted dependent upon the situation. The design is created and anticipated on the informational collections required for a specific use case. 

   When the pattern has been created, it very well may be saved for sometime later or disposed of when not, at this point required.
