Along with the Data Warehouse, there is another concept that is sometimes confused. We are referring to the data lake . What are the main differences between data lake and data warehouse?
Data types and structure. Data warehouses tend to be organized, while data lakes tend to obtain somewhat disorganized information because the source ingests it directly.
The objectives of data lakes are primarily to achieve profitability and reduce the cost of data management. They do not need to be adapted to any specific system, which makes the initial phases of the work easier. Data warehouses are more complex.
Different user profiles. While data lakes are run by data engineers and data scientists, data warehouses are used by data analysts and business analysts. They require that the information is pre-processed, at least at a certain level.
Data engineers use data lakes to store incoming data. Data warehouses are set up for read-only use by analyst users, and they can add information if they see fit.
Size. Data warehouses are smaller, due to the selectivity of the information they collect. Data lakes are much larger because they hold all the data that could ever be considered important to the company.
Advantages of Data Warehouse
There are several advantages to having a Data armenia whatsapp data Warehouse . Below we highlight those that best reflect the qualities of this system:
They provide coherent information on various multifunctional activities.
It helps to integrate very different sources of data and information in an agile and simple way.
Reduces response time when specific reports or reports need to be prepared.
Information from various sources can be accessed from a single point.
Great capacity to maintain historical data, important for those who need to perform retrospective studies and comparisons with other moments in history.
Data Warehouse Examples
There are numerous examples in everyday life of companies that rely on Data Warehouses . One example is that of the retail trade , which often stores data related to distribution and marketing in order to know where their item is located. The information retained also helps them improve services, monitor offers and better understand the purchasing behavior of users.
Another interesting example is in the world of insurance and banking . Here a number is capable of moving millions and millions of profits or losses, which is why both Big Data and specific tools such as this Data Warehouse are essential in the financial and economic fields.
Finally, to broaden the scope and help the reader better understand the multiple applications of data storage, we must refer to health care . In order to offer the best treatments and efficient help, it is essential to have forecast reports to know what is best suited to each person, each patient.
This formula, as well as others closely linked to the advancement of data management and conscious storage to take advantage of business intelligence, are covered in several of the training proposals of the EAE Business School . Specifically, we must refer to the Master in Big Data & Analytics and the Global Master in Business Analytics and Data Strategy .
