“From an IT operations perspective, the stability of the data warehouse and fast response to any issue are critical for us. Adastra has been supporting our DWH in a way that gives us confidence in daily operations. Thanks to monitoring, we often resolve incidents before users even notice them, and during infrastructure changes, we have access to enhanced support. This is essential for running a retail network of our scale.”

Challenge

All Data, Immediately, for Everyone

Albert had been working with data for years, but as the market accelerated, traditional reporting was no longer sufficient. The company needed to:

  • quickly retrieve specific transactions or audit records
  • handle a growing number of ad-hoc requests from operations
  • consolidate an increasing volume of heterogeneous data
  • relieve operational systems that were becoming overloaded

Most importantly, Albert needed to ensure that all key data would be reliably available every morning-for management, planning, and individual stores.

From strategic decisions at headquarters to day-to-day operations at specific locations.

A critical part of this was also data quality management-not just collecting data, but ensuring it is properly stored, processed, and securely accessible across the organization.

Solution

Multi-layer Architecture, Near Real-Time Processing, and Expert Mentoring

The solution was designed as modular and scalable.

At its core are two interconnected data warehouses built on Oracle database technology, specifically optimized for processing data either daily or in near real time. These data warehouses integrate and store retail data from POS and e-commerce systems, as well as logistics and commercial data from the client’s ERP systems.

The solution also includes OLAP databases based on Microsoft technologies—both multidimensional and tabular.

On top of the data warehouse and OLAP layers, additional customer systems for reporting and business intelligence are connected, enabling efficient calculations and deeper analysis across regions, time periods, product assortments, and customer segments.

Beyond analytics, the data is also used for operational management and to support the client’s business applications.

The receipt data warehouse provides detailed visibility into every individual transaction, significantly accelerating audits and customer service processes, while opening up new possibilities for retail analytics.

“We have been working closely with Adastra for years on the development of our data warehouses, which are essential for the daily operation of all BI layers used to manage the company—from top management down to in-store staff. In my role, I bridge business requirements and the technical world—we discuss requirements together and choose the most suitable technology based on multiple criteria. When development or support from Adastra is needed, I value that the collaboration is straightforward, open, and focused on long-term sustainability and further development. They are able to recommend direction, highlight potential risks, and propose effective solutions.”
