If a data lake isn't well managed and governed, it can become more of a swamp than a lake. Data is dumped into the platform without suitable oversight and documentation, making it difficult for data management and governance teams to keep track of what's in the data lake. That ...
A data lake is a low-cost data storage environment designed to handle massive amounts of raw data in any format.
James Dixon, the CTO of Pentaho and the creator of the term “data lake”, presents a challenge to the big data community in his blog “Union of the State - A Data Lake Use Case”. Dixon argues that it is time to start figuring out how to make the data lake a time machine for a...
A data lake stores the raw data from various data sources in a standardized open format. However, use cases such as data exploration, Interactive Analytics, and Machine Learning require that the raw data be processed to create use-case-driven trusted datasets. For Data Exploration and Machine Le...
Origin of the Term Data Lake Coined in2011by James Dixon, the term “data lake” was initially a theoretical concept fordata scientists. However, it has since gained traction among non-specialist users. Many companies have functional data lakes, andmanaged service providersoffer them as ready-mad...
With a data governance and privacy solution, you can ensure data accessibility, trust, protection, security, and compliance across your data. This video shows a data fabric use case for implementing a data governance and privacy solution in Cloud Pak f
Ultimately, the choice between a cloud-based and on-premise data lake depends on factors such as organizational requirements, budget constraints, and the specific use case for the data lake. Many organizations opt for a hybrid approach, combining elements of both cloud and on-premise solutions to...
