What is a data lake and a data swamp?
A data lake is a data storage architecture that stores raw data from all of an organization’s data sources. Unlike a traditional data warehouse, a data lake does not require any prior data modeling, allowing organizations to store unstructured, semi-structured, and structured data of all kinds.
However, without proper data governance and a well-thought-out enterprise architecture, a data lake can quickly become a data swamp, which can lead to a loss of business value and relevance.
In a data swamp, stored information is not managed properly. Data can be duplicated, inaccurate, incomplete, or outdated, which can lead to errors in analysis and decision making.
