What term describes a data lake repository where data quality is poor and finding information is nearly impossible?
Answer
Data Swamp
As the industry moved beyond the initial concept of the basic data lake, a significant practical problem emerged: without proper oversight and governance, simply collecting vast amounts of raw data could render the repository unusable. This poorly managed state, characterized by low data quality and extreme difficulty in locating relevant information, is referred to as a 'data swamp.' The recognition of this risk spurred architectural advancements, like the development of the data lakehouse, which aims to introduce warehouse-like controls to prevent the lake from devolving into an unmanageable swamp.
