What’s the size of the global datasphere? IDC reports that in 2019, it was around 40 zettabytes. It’s projected that the sector will increase to 175 zettabytes in 2025. In terms of time, if one person wanted to download the entire package in 2025, he/she would have to spend 1.8 billion years! The revenue from data will rise, as well as the demand for data warehouse solutions.
Undoubtedly, to deal with Big Data and scale properly, businesses require the appropriate tools. It’s essential not to use a sledgehammer to crack a nut. In other words, you should understand your business goals and build the software that matches these needs perfectly. At DICEUS, we design and implement custom systems tailored for each client exclusively.
Overall, data warehouse solutions remain the universal tools for data management/analysis, so we’re going to talk about them today. The guide unveils the basics of DWH concepts, the purpose of this software, pros, and cons. It also provides a review of data warehouse vendors that deliver off-the-shelf and custom products.
In the beginning, let’s understand what are databases and data warehouses, how they work, which architectures exist, and what are other approaches to data processing. The section may look a bit complicated, but give it a chance. These are the very basics described in simple words. After studying this section, you will understand DWH better and will be able to spot the best warehouse solutions.
The simplest definition of data warehouses sounds like “software systems for data analysis and reporting”. These apps are repositories that contain all business information. They are cores of business intelligence departments thanks to rich functionality in the area of reports and analytics. Warehouses keep the integrated data from various sources, both current and historical.
At this point, let’s find out the difference between a database and a DWH. Even experienced business people confuse these terms often. Here’s the main contrast:
It’s clear that DWH apps are highly useful. But what is the primary purpose of a data warehouse? Well, the function is to extract, transform, and load (the approach is known as ETL) information. The goal is to gather the essential data under one roof, get market insights, and improve business processes, eventually.
The ETL model is the basis of data warehouse solutions. Information in them follows the same path in the majority of cases. Initially, a tool receives data from various sources like CRM apps or social media. Then, a DWH integrates and cleans info to make ready for analysis. After integration, the primary module stores data and delivers it to users who can then mine it, create queries, send it to other systems.
Based on the process, Renson Obongo, BI consultant at Analytics8, defines four core elements and steps in any DWH:
As for the difference between structures, there are basic warehouses that support simple queries and more advanced tools with staging and data mart layers. Here, staging areas improve integration accuracy and cleanse information better. Data marts help to deliver the needed info to target groups of users. In this case, the difference of a data warehouse vs. a data mart is simple: the latter is just a structural part of the former.
Now, we have a complete data warehouse meaning. It’s a system that gathers, transforms, and stores data and metadata, organizes it and enables analytical opportunities.
Yes. Apart from traditional SQL data warehouse programs, there are other approaches to data management. It happens that even the best data warehouse vendors can’t provide a product that deals with all the modern challenges. With the rise of new data types from IoT devices, video hustings, audio units, new challenges arise. Big Data changes the world. Regulators reveal new standards. Privacy becomes even more essential.
With all these updates, it seems a good idea to consider alternative data processing options. Here are the most prominent ones:
If you want to develop the best warehouse solutions or upgrade the existing ones, look at innovations. The mentioned alternatives may be better than traditional DWH tools for some businesses. We can help with an analysis of your company goals and issues to define the most suitable software type. But if you’ve decided to deploy a DWH, don’t forget about data warehouse solutions comparison, including one for pros and cons.
Of course, don’t forget about the reliability of data warehouse solutions. You can find more on this topic in our article dedicated to DWH security.
As with any digital tool, a DWH isn’t a magic wand. It can’t save your company from all failures or prevent issues with the software, hardware, customers, and regulators. However, it can optimize the majority of processes. Further, we want to compare critical benefits and drawbacks. Note that the next sections are dedicated to traditional DWH structures. The analysis of data warehouse advantages is provided by Daan van Beek, owner of Passionned Group.
Ultimately, the perfect switching periods are different for different companies. But there’s one sign that can help you to identify this moment. While most of the companies start with basic data management tools like Excel or Google Spreadsheets, they may face performance problems. Due to limitations of the software, programs/sheets start loading slower, data start missing, and employees start complaining. Departments also may want to make data shareable to generate better insights or optimize processes.
As well, here are three questions that help to learn if you need a new tool:
It may be tough to choose the correct structure and implementation model. Different companies required different tools, for instance, SMEs are often happy with basic apps, while multinational corporations required dozens of staging layers and data marts. We handle custom development by making unique products with the needed features only. With tailored software, you can avoid the majority of the mentioned disadvantages.

Moving to the examples, let’s check which DWH systems are considered the best. We will analyze them by functions, advantages/drawbacks, pricings, client focuses, and platforms. Note that this section features only off-the-shelf or prepackaged software that supports little to no customization. For custom products from Diceus, check the last paragraph.
Also, be aware that the selection is mostly based on Gartner’s magic quadrant methodology for data management. We will look at the market leaders and one visionary – a company that has a strong market vision but not as good implementation. There are no challengers in the recent report, and we don’t want to focus on niche players.
Being a part of the famous cloud system Amazon Web Services, Redshift enables plentiful online data analysis opportunities. It utilizes standard architecture and SQL tools that support various data types. The system relies on high-performance hardware, re-replicates info automatically, and offers the Spectrum tool to analyze data in Amazon S3 directly. Still, it features relatively slow query planner and high hourly costs for idle times.
BigQuery is a native system developed by Google and based on its cloud platform. It’s a serverless DWH solution with SQL support and automated data processing. It also supports connected apps like Hadoop and Spark. The tool is pretty fast on small and medium scales but may become slower and slower as the size increases. As for efficiency, the software will be much cheaper for teams with workload spikes. BigQuery requires some coding skills.
Instead of a single product, IBM offers a family of different data warehouse solutions – Db2. They’re based on the AI features, comprehensive processing, scaling, and universal deployment options. You can choose a cloud or a local tool, get an integrated system, or extend the capabilities with IBM InfoSphere DataStage – a BI and DWH module focused on data integration. It features the combined HDW/LDW architecture and Hadoop.
This one is the only visionary from the Gartner’s magic quadrant. MarkLogic offers a comprehensive, unified system to manage enterprise data.
