Conclusion
What is a Data Lake?
A data lake is a storage system that allows the collection, storage, and analysis of large volumes of raw data in its native format. The central idea is to store a vast amount of data without the need to structure it beforehand, unlike data warehouses that require the definition of schemas before storing data.
This approach brings significant flexibility, allowing data to be manipulated and analyzed in different ways as needs arise.
What is the difference between Data Lake and Data Warehouse?
The main difference between a data lake and a data warehouse lies in the flexibility of data manipulation. Data warehouses are optimized for rapid analysis and complex queries of already processed and structured data, while data lakes are designed to handle large volumes of data in various formats, including documents, images, videos, and other types of unstructured data.
This capability makes them especially useful in scenarios where speed in obtaining insights is not the only critical factor, but rather the ability to explore and discover new opportunities or insights from raw, heterogeneous data.
