In the big data era, it is impossible to imagine a well-functioning business without a serious well-managed digital infrastructure. Modern data warehouse solutions (DWS) provide great opportunities for storing and managing terabytes of information, ensuring the development of entire industries and even small countries.
Today, DWS is used by enterprises of all sizes to improve the quality of business intelligence, enhance their decision-making capabilities, and gain the best competitive advantage. According to forecasts, the volume of the global DWS market will grow at an average annual rate of 10.7% and will reach $51.18 billion by 2028.
Main factors contributing to this growth include:
- the need for a dedicated storage system
- the demand for column-oriented data warehouse solutions to perform advanced analytics
- the need for minimal latency, real-time viewing and analytics of operational data
Market growth will also be driven by increased enterprise awareness of the growing data streams from various sources and the introduction of modern business intelligence tools. New industry trends involving virtual storage and AI will surely provide tremendous benefits.
The question is, which data warehouse solutions are the best? Due to the COVID-19 epidemic, many providers pursue multiple business and marketing strategies, updating their product portfolios with customized offers. Google LLC did just that, providing speed-boosting capabilities for its BigQuery cloud storage, allowing analysts to complete tasks five times faster.
At DICEUS, we offer our review of the best DWS.

What is a data warehouse?
The data warehouse (DWH) is an electronic database designed to collect data from various sources, analyze and manage them.
DWH acts as a channel between operational data warehouses and supports composite data analytics. Fragments of data from the warehouse, which are stored in the “data mart” for quick access, can be used across departments of the enterprise. To effectively support decision-making, data is retrieved from various sources and loaded into the warehouse.
DWH can be organized into tables, stripped of redundancy, and transformed for consistency using ETL extraction, transformation, and loading. It stores structured data, which is well organized and searchable. It can be easily accessed by anyone in the organization. It is predictable, reliable, and applicable in most business environments because they provide:
- Fast indexing, cataloging and searching
- Easy launch and support
- Accessibility for business users
It is the core of a business intelligence system built for data analysis and reporting. Storage costs are high, so they are not best for storing large volumes, semi- and unstructured data.
Types of data warehouse solutions
There are three main types of data stores:
Enterprise data warehouse (EDW)
It is a centralized corporate repository. It provides a unified approach to organizing and presenting data suitable for enterprise-wide decision-making support. EDW also offers the opportunity to categorize data and provide access according to different sections.
Operational Data Warehouse (ODS) is a database designed to integrate data from disparate sources to be further used by reporting applications. The data is updated in real time, so that it can be conveniently used for routine actions.
It is a part of the data warehouse dedicated to a specific direction, such as sales or finance. In an independent storefront, you can collect data directly from sources.
According to the way of implementation, DWH can be both physical and virtual.
Data warehouse features: how it all works
The data warehouse acts as a central repository where information comes from one or more sources, for example, from a transactional system and relational databases. By combining information, an organization can comprehensively analyze customers. The warehouse enables data mining to identify patterns that can lead to increased sales.
The data can be structured, semi-structured, and unstructured.
It is processed, transformed, and loaded so that users can access the information in the warehouse using business intelligence tools, SQL clients, and spreadsheets.
Specialized solutions often include a number of useful features for managing and consolidating data. You can use them to extract and use data from different environments, transform data and remove duplicates, and ensure consistency in analytics. Some contain machine learning algorithms and built-in artificial intelligence.
Main functions and capabilities of DWH
- Associated tools for entering, adding, extracting, and manipulating data
- Extraction capabilities from many types of source files
- Ability to load and normalize structured, semi-structured, or unstructured data
- Data transformation (cleanup, deduplication, consistency)
- Data consistency for different naming conventions
- Built-in and offline storage and processing optimization
- Complete overview of all corporate data
- Multiple deployment options (private, public, on-premises, hybrid cloud)
- Available as a Service (Automated Infrastructure Management)
- Integrated machine learning algorithms, AI
- Sharing data with controlled access
- Built-in encryption for high data security
When delivered over the cloud, solutions are even more flexible. As with other as-a-service environments, business leaders can add and remove features to meet changing needs.

Case study: how we developed a DWH for a bank
Bank al Etihad – a Jordanian bank that offers a wide range of financial services, including online payments and mobile banking, approached us with a request to create a DWH with a robust architecture. It is one of the fastest-growing banking structures in Jordan, looking to keep pace with the current global economy and technological advances.
They had a pressing need to validate the information from reports, clarify business reporting needs, and improve storage architecture to achieve a smooth and consistent workflow. The task was to develop and integrate DWH solutions and implement a liquidity risk management system for cooperation with the European Bank for Reconstruction and Development. The ultimate goal was to develop basic analytic and reporting dashboards.
The project was managed by managers with PMI certifications. A serious technological stack was used ─ PL/SQL, Oracle Apex, Oracle SQL Developer, Git, Jira, Microsoft Project. In the shortest possible time, we presented a new design of the storage architecture ─ the software core of the management reporting system based on Oracle UBS FLEXCUBE in partnership with the Frankfurt School of Finance and Management International Advisory Services.
DICEUS specialists implemented a complex data warehouse for connecting and analyzing business data from 15 heterogeneous sources based on their information model with data marts for the entire bank workflow.
We have developed and implemented a process for regular monitoring and analysis of key banking operations, reporting systems for loan and deposit portfolios. Several tests were carried out and the project was delivered on time.
Our work has reduced the load on commercial transaction systems and paved the way for optimized integration in the future. The multi-level reporting system on Oracle BI makes it possible to track every operation and transaction. We’ve created a single and unified source of information for scalable and reliable reporting with an interface that provides all the easy-to-navigate elements.
As a result, the client got what he never had before – a data model for in-depth analysis, strategic planning, and forecasting. We have enhanced DWH to ensure efficient workflow and information reliability. Thanks to automation, the solution is ideal for consistent monitoring and analysis of key banking transactions in real time.
