Data Lake

What is a data lake?

Data lakes are large collections of data from many, often disparate, sources spanning an entire organization. To create a data lake, your data sources may include sensors or IoT devices, website traffic, LinkedIn or Twitter activity, and business sales.

The amount of data stored in data lakes is huge, sometimes up to petabytes. A data lake stores data in a more natural way than a data warehouse. It helps in collecting data from different sources and structures. It is important for an organization to properly set up and maintain a data lake, taking into account aspects such as data lake management, privacy and security.

What are the benefits of a data lake for companies?

Regardless of source or format, data lakes are becoming a central part of a company's data strategy. The business benefits of a data lake include:

Respond to today's sheer volume and variety of data, rising user expectations and a rapidly globalizing economy.
Remove the barriers that separate all business data and empower organizations to unite all disparate data.
Simplify the analysis of all data at once, without obstacles.
Provide a single, unified view of all business data and the flexibility to access data in multiple ways.

A data lake is a concept consisting of a collection of storage instances from different datasets. These resources are stored in a near-exact or even exact copy of the original format and added to the original data stores.
