Lots of technologists are promoting replacement of data warehouse by data lake. In the view point of our data science team, a modernized data warehouse should carry its own value for the analytics nowadays.
There is an article by TDWI.org sharing the viewpoint of CEO of Yellowbrick – Neil Carson what vital technology and tools being used.
His opinion is aligning with our data science evangelist – Samuel Sum on Hadoop. It is a large-scale data store but it is not easy to access and manage in many situations. It is always better to have a structured data store like data warehouse for easy user access. Also, a key-point of a successful data analytic environment is the storage speed storing the data. With SSD (flash memory), the data warehouse (both ETL and access) are now several times faster than before.
Finally, the editor of this webpage suggests read an article of Samuel Sum – talking about the Data Lake (Data Lake VS Data Warehouse).
