“Based on the requirements above and the problems of the traditional solutions we have created a concept called the Data Lake to describe an optimal solution. If you think of a datamart as a store of bottled water – cleansed and packaged and structured for easy consumption – the data lake is a large body of water in a more natural state. The contents of the data lake stream in from a source to fill the lake, and various users of the lake can come to examine, dive in, or take samples.”

“Perhaps the most transformative aspect of an analytics architecture that incorporates a data lake is that users do not need to have the possible answers in mind when they ask the questions.”

“The difference between a data lake and a data warehouse is that in a data warehouse, the data is pre-categorized at the point of entry, which can dictate how it’s going to be analyzed.”

“The data lake, in turn, supports a two-step process to analyze the data.”

“One phrase in particular has become popular for describing the massing of data into Hadoop, the “Data Lake”, and indeed, this term has been adopted by Pivotal for their enterprise big data strategy.”
