When a business is looking for a way to store large amounts of data to be used and analyzed in the future, it can consider two major solutions - a data lake or a data warehouse. While it is important to note that an organization can benefit from either of these technological solutions, they are not interchangeable. Understanding what each does, their benefits and drawbacks, and other factors will help ensure you choose the right solution for your specific needs.
The concept of a data lake is still relatively new, though it is growing in popularity among industries that depend on holding massive amounts of data for future use. In this system, data is collected from different sources and stored in their native formats. There are no set limits for formats, size, or other factors, making it extremely easy to direct data into the lake. The data can come from transactions, document preparation, reporting software, logs, machine to machine, and other sources.
Once the information is saved into the data lake, it can be pulled out and used by any company’s authorized systems or employees. As it is being pulled out, the data is transformed into whatever format the person or system needs it to be. A data lake uses the ELT (Extract, Load, Transform) process, making it extremely fast and easy to add new information to this system. The key benefits of a data lake are:
Cost-effective – Data lakes benefit from the economies of scale since they can always take advantage of the largest storage solutions. Most data lakes are housed in the cloud, where storage space is affordable.
Format agnostic – There is no need to transform the data from one format to another before feeding it into the data lake, making data transfer much faster and easier.
Easily sharable – Using a simple permissions-based system, any person or system that needs data can access it. However, they will need to be able to transform the data into a format they can use.
A data warehouse is another system designed to store and manage large amounts of data. With this option, however, the data is kept in files and folders formatted in specific ways to make them better organized and easier to find. And it makes sense because one of the primary uses of a data warehouse is to facilitate analytics to improve decision-making and overall business intelligence. Data warehouse systems use the ETL (Extract, Transform, Load) process, which requires additional processing when the data is flowing in. When pulling the data out for use, it will already be in a useful format so that the process will be faster and easier.
Like a data lake, companies can feed information into a data warehouse from multiple systems. Once fed into the system, it is also intended to remain in place, unedited, from that point forward, except in specific situations. When the data is needed, people or systems will pull it out and use that copy for whatever tasks need to be completed. The advantages of a data warehouse include:
Focused on business use – While technical systems and staff often use data lakes, a data warehouse is formatted specifically for use in business operations, including reporting and analytics.
Positive return on investment – A properly handled data warehouse implementation will support an entire business intelligence strategy. This has been shown to help businesses achieve excellent ROI.
Easier to access – Information within a data warehouse does not need to be formatted when pulling it out, making it faster and easier for those who are accessing it.

When creating a new data warehousing environment, there is much to consider. One of the most important elements to be aware of is the fact table. The fact table is one of the central tables within a data warehouse that uses a star schema. There are three main types of fact tables, each of which will store a different set of information to be analyzed and used as part of an overall business intelligence strategy.Explore
Data Warehouse as a Service (DWaaS) is a business solution that has been rapidly growing in popularity. It enables companies to secure the information for their data warehouse on cloud infrastructure, making data easily accessible by those who need it but protected from thieves and hackers. Organizations considering this service need to understand its benefits, how it can be integrated into their existing systems, and what options are available to them.Explore
Cubicles, workstations, and paper reports are fading from memory – the workplace is going through constant and rapid evolution. A new era of open environments, tele-commuting, and digital workspaces has replaced the analog office setting. Moving forward, digital workflow transformation will have even farther-reaching effects on organizations and employees. Systems, tools, apps, and processes are being digitized and migrated to the cloud. This cloud-enabled evolution will in turn be impacted significantly by artificial intelligence (AI) capabilities.Explore
IT is having an existential moment, if you will, where it is no longer enough just to support business enablement. IT must also power next-generation digital business models emerging from the widespread adoption of social, mobile, analytics, and cloud. This leads to a strategic shift wherein organizations must optimize their business and IT operating models to simultaneously extract synergies and improve performance. Many organizations are struggling, however, with how to empower IT to harness this wave of disruption and build a sustainable next-generation operating model.Explore
