Читать книгу Data Lakes For Dummies - Alan R. Simon - Страница 30

Turn the clock back to the early 2010s when big data burst onto the scene. Almost every organization was exploring how this new generation of data management technology can overcome many of the barriers and constraints of relational databases, particularly for analytical storage.

Big data promised — and delivered — significantly greater capacity than was possible with relational databases. With big data, you can store unstructured and semi-structured data alongside your structured data. You can also bring new data into a big data environment with lower latency than with relational databases.

Wait a minute! That sounds just like the description of a data lake! So, is a data lake just another name for big data?

Well, sort of … possibly … or maybe not… .

The best way to think of the two disciplines in relation to one another is as follows:

 Big data is the underlying core technology used to build a data lake.

 A data lake is an environment that includes big data but also potentially other data management technologies along with services for data transmission and data governance.
