FAQ4: What is a data lake?
A data lake is a centralized repository that allows you to store all your structured and unstructured data at any scale. You can store your data as-is, without having to first structure the data, and run different types of analytics—from dashboards and visualizations to big data processing, real-time analytics, and machine learning to guide better decisions.
FAQ5: What is a data warehouse?
The data warehouse only stores structured data from one or more disparate sources, which will be processed later for business users to provide meaningful business insights into corporate performance. The data warehouse is the core of the BI system which is built for data analysis and reporting. By the way, if all the processed data is stored in data warehouse, the cost will be high.
