![]() Given how “big” that data can get, data lakes are critical as they provide a platform where data can be stored efficiently, safely, and easily retrieved for analysis. Data scientists can analyze the data generated to improve customer retention rates and reach out to new ones. Organizations generate large volumes of data from their consumers, operations, and processes. See More: What Is Platform as a Service (PaaS)? Definition, Examples, Components, and Best Practices Data Lake Architecture There’s also a general lack of skill set required to use tools in data lakes that may necessitate new recruitments or internal professional developments leading to increased costs. One of the main challenges that data lakes present is that since the raw data is stored “as is”, they must have specific processes for cataloging and securing data failure to which queries may not be fulfilled. Data lakes are also highly scalable and support many languages. They also support faster querying as data scientists can perform analytical queries independent of the production environments. Data lakes allow business intelligence (BI) tools to directly pull data when needed, making it a complementary analytical support tool. This ensures more efficient analytics.ĭata lakes provide solutions to organizations looking to accumulate all the data from distinct data sources in one place to generate insights from it. Modern data lakes frequently have a cloud-based analytics layer that optimizes query performances against data in a data warehouse. ![]() Modern data lakes provide low-cost data stores that can be scalable by storing their data in the clouds, unlike traditional ones, which use on-premise storage facilities. Data stored in warehouses are used chiefly by business analysts, while data lakes can be used by data scientists, data developers, and business analysts. Data lakes also provide a cost-effective way of storing data. Unlike data warehouses, data stored in data lakes don’t have to be pre-processed. They allow for secure and efficient raw data storage without fixed limitations for future analytical performances. Demand for space for storage of this data has therefore been on the rise, which data lakes provide.ĭata lakes provide a repository for storing vast amounts of data in structured, semi-structured, and unstructured data forms. ![]() To get a competitive edge in the market, organizations have collected a lot of data from their consumers and key stakeholders. A data lake is defined as a data system designed primarily for unstructured data, where one can store information in object storage units or “blobs” to power analytics, machine learning, and other data uses in a different ex-situ location.
