Data Lakes vs Data Warehouse: Key Differences

The term data lake has been on the rise and is being used more frequently, but it’s important not to confuse this with data warehouses. While both are used for storing data, they are not interchangeable terms. Many view data lakes as more beneficial for their company- in fact, 43% of businesses reported that they found data lakes increased their operational efficiency.

What is a Data Lake?

data lake can be thought of as a large pool of unprocessed data that is stored in its original format. Data lakes are fed data from real time sources such as operational databases, social media sources, and CRM tools. When using a data lake, you’re able to store all of your data at any scale. This essentially means that you can store your data untouched, as-is, without the hassle of structuring the data first. Learn more about how you can advance your business using data lakes here.

Data Lake vs. Data Warehouse

The terms data lake and data warehouse are often used interchangeably. However, data in a data warehouse has been cleaned and structured for a specific use, where data in a data lake has not. The two types of data storage are often confused, but are much more different than they are alike. In fact, the only real similarity between them is their high-level purpose of storing data.

The distinction between the two is important because they serve different purposes and require different sets of eyes to be properly optimized. While a data lake works for one company, a data warehouse will be a better fit for another. The one undeniable fact is that organizations who successfully generate business value from their data will outperform their peers.

Why People are Using Data Lakes

The amount of data being gathered is growing exponentially. With the advancements in compute power, businesses can afford to leverage this data to drive decision making. Data lakes provide a cost-effective way to store years of data while maintaining data integrity so that it can be used in the future.

Using data lakes allows for new types of analytics such as machine learning over new sources like log files, data from click-streams, social media, and internet connected devices. This helps in identifying opportunities for business growth at a much faster rate through attracting and retaining customers, boosting productivity, and making informed decisions.
