If your organization produces mountains of data that you do not need to transform into insights right away, a data lake can be a good option. Other data lake solutions to look into including the open data lake solution, Qubole. There is also the infinitely scrollable data lake with a relational layer, Infor Data Lake. The phone saves the footage with additional information that is typically easy to understand, such as the date, time, and, sometimes, shooting location.
- Database Management Systems store data in the database and enable users and applications to interact with the data.
- In a data lake, the catalog defines where existing data can be found and in what format .
- One of most attractive features of big data technologies is the cost of storing data.
- The choice of which big-data storage architecture to choose will ultimately depend on the type of data you’re dealing with, the data source, and how the stakeholders will use the data.
- As mentioned, a data warehouse provides clean and organized data.
Given the scale and flexibility of data lakes, it’s easy to ask, “what is a data warehouse used for?” Despite their size, data lakes aren’t suited for every task. Too much unprioritized data creates complexity, which means more costs and confusion for your company—and likely little value. Organizations should not strive for data lakes on their own; instead, data lakes should be used only within an encompassing data strategy that aligns with actionable solutions.
Data stored here will never turn into a swamp due to intelligent cataloging. End-users of a data warehouse are entrepreneurs and business users.

In a data warehouse architecture, the catalog controls how data is loaded. This is why warehouses are considered less flexible but faster because data gets a structure first, then it is written in proprietary optimized formats. In a data lake, the catalog defines where existing data can be found and in what format . Data lakes have traditionally been thought of as flexible and slower because data gets written in any format and then structured later.
The benefits of a data lakehouse
And data lakes in the cloud are an effective way to store diverse data and can scale up to petabytes and beyond. Traditional on-premises enterprise databases are not equipped to support these newer demands. Deployed on dedicated hardware acquired by the organization and installed and managed by the IT team, they are expensive and time-consuming to set up, operate and scale. They can also take months to upgrade and often require a fair amount of regular maintenance that only an experienced database administrator can provide. How do these options come into play with evolving business needs? Let’s start with an explanation of their key details and the differences between them.
One of the key factors in Data Lake vs Data Warehouse is the choice of tools and software. Data lakes can be used in a variety of sectors by data professionals to tackle and solve business problems.
Database vs. data warehouse vs. data lake: which is right for me?
You can store, retrieve, and analyze it for specific purposes for that reason. The manufacturing department uses its data mart to analyze assembly line efficiency, process data to input into AI solutions and maintain procurement databases. Not all companies need to store information from multiple applications.
Data lakes can store structured, semi-structured, and unstructured data. Data lakes delivered in Microsoft Azure are built on storage accounts with Data Lake Storage Gen2 enabled when creating the storage account. Processed data is data that is collected and translated into usable information. In other words, processed data can provide actionable insights to help you improve your marketing campaigns and processes to drive better results for your business. When it comes to data storage, there are two distinct types of solutions that you can use—a data warehouse and a data lake. Both of these solutions have their own benefits, but it’s important to understand the key differences between them so that you can choose the best option for your needs.
With a holistic view of your costs across AWS and Snowflake, your engineering teams can make informed decisions to better optimize your product or features for profitability. But you would still need to translate that raw data into valuable and understandable information to remove the guesswork out of your decision-making. Think of the different data sources as the various departments in your organization depositing organized data in one place. The goal is usually to help provide practical insights into an organization’s multiple operations. An increasing number of tools can help your organization query semi-structured data, such as Snowflake. Structured data refers to stored data in a standardized format, such as rows and columns, to be more easily understood.
The importance of choosing a data lake or data warehouse
Database Management Systems store data in the database and enable users and applications to interact with the data. The term “database” is commonly used to reference both the database itself as well as the DBMS. There are several differences between a data lake and a data warehouse. Data structure, ideal users, processing methods, and the overall purpose of the data are the key differentiators. An enterprise data warehouse defines clear structures for how enterprise-wide data is collected, organized, and queried.
It could also be used by a manufacturing department to analyze performance and error rates to enable continuous improvement. Data sets within a data mart are often utilized in real time, for current analysis and actionable results. Data warehouses are large storage locations for data that you accumulate from a wide range of sources. For decades, the foundation for business intelligence and data discovery/storage rested on data warehouses. Their specific, static structures dictate what data analysis you could perform. Typically, data warehouses store historical data by combining relational data sets from multiple sources, including application, business, and transactional data.

Maintaining a data lake isn’t the same as working with a traditional database. It requires engineers who are knowledgeable and practiced in big data. If you have somebody within your organization equipped with the skillset, take the data lake plunge.
Data warehouses only hold processed data that has been used for a specific purpose. One of the benefits of a data warehouse is that storage space is not wasted on data that may not be used. Data lake stores raw data that can sometimes have a specific future use and sometimes just for hoarding. A Data Warehouse is a large repository of organizational data accumulated from a wide range of operational and external data sources.
There is an increasing reliance on both structured and unstructured information, and the latter has grown exponentially. Data warehouses can’t handle different data formats and workloads. Traditional and siloed databases were the original repositories for storing and managing data. Fast-forward a decade, and organizations could only go so far with the large amount of information generated day to day and minute to minute. Access and load data quickly to your cloud data warehouse – Snowflake, Redshift, Synapse, Databricks, BigQuery – to accelerate your analytics.
Unstructured data
But, the data in lakes does not demand as many compute resources as it takes to organize warehouse data. That also makes data lakes cost-friendlier for storing vast amounts of data than data warehouses. The most significant difference is that while data lakes hold all manner of data, processed or not, data warehouses keep only structured data. Data lakes also keep the data in a flat architecture instead of the structured database environment in a data warehouse. Adata mart is a subset of a data warehouse that benefits a specific set of users within the business or business unit. A data mart could be used by the marketing department of a manufacturing company to determine the ideal target demographic or persona to aid in the development of marketing plans.
Data lake vs data warehouse: Key differences
Building a data warehouse can be very expensive and time consuming to properly review your source systems, design a data model, and create the necessary ETL to process it.

Data Lake vs. Data Warehouse: What’s the Difference?
A data warehouse is a relational database that can handle, store, and bring to one place structured data sets coming from multiple sources. Data warehousing supports business decision-making by analyzing varied data sources and reporting them in an informational format. The data lakehouse is the newest data storage architecture that combines the cost-efficiency and flexibility of data lakes with data warehouses’ reliability and consistency. Instead, information from nearly any source can stop in a data lake during its lifetime.
A data warehouse is a good choice for companies seeking a mature, structured data solution that focuses on business intelligence and data analytics use cases. However, data lakes are suitable for organizations seeking a flexible, low-cost, big-data solution to drive machine learning and data science workloads on unstructured data. Data lakes and data warehouses are both storage systems for big data used by data scientists, data engineers, and business analysts. But while a data warehouse is designed to be queried and analyzed, a data lake has multiple sources of structured and unstructured data that flow into one combined site.
Additionally, because the structure of the data is predetermined, it requires minimal maintenance once set up. Although both data warehouse and data lake are commonly applied for big data storage, the concepts are not identical. A vast collection of unstructured raw data is known as a data lake. A data warehouse, on the other hand, is a collection of processed data that has already been formatted, sorted, and structured for a particular purpose. The data warehouse is the oldest big-data storage technology with a long history in business intelligence, reporting, and analytics applications.
Data lake allows greater flexibility in how the data is eventually used because they keep the data in its raw state. Fulfill the data lake vs data warehouse promise of the Snowflake Data Cloud with real-time data. Support for analytics nodes that are designated for analytic workloads.
