KEY DIFFERENCE. customer feedbacks, phone logs, GPS locations, emails, text messages photos, tweets) into Hadoop/NoSQL. It takes structured, non-structured or semi-structured data as an input. OLTP vs. OLAP. Whereas Big Data is a technology to handle huge data and prepare the repository. When new data is added, the changes in data are stored in the form of a file which is represented by a table. One of the major differences between the two is Data Warehousing is an architectural concept in data computing whereas the Big Data Solution is technology. Hence, this is another difference between Data Warehouse and Business Intelligence. Hadoop as a data platform is more compelling for storing and capturing big data in a DW environment, to process that data for analytic purposes on other platforms. Snowflake eliminates the administration and management demands of traditional data warehouses and big data platforms. In Data Warehouse Data comes from many sources. Big data doesn’t require efficient management techniques as compared to data warehouse. Size : The size of the Data Warehouse may range from 100 GB to 1 TB+.

It involves the process of extraction, loading, and transformation for providing the data for analysis. Organizations know the requirement to combine their business with traditional data warehouses, with less structured and big data sources at one side and their historical business data sources on the other side. Traditional data warehouse solutions were originally developed out of necessity.
