What is a Data Warehouse?

A data warehouse is a system that can pull a lot of data from many different sources within an organization and present it in a different, usually user-friendly way. It is often used for analyzing and reporting.

Its main purpose is to make important business decisions easier and faster to take.

How Data Warehouse works?

Data Warehouse collects complex queries, data, factors or numbers from different sources (CRM, ERP, Banking, User Database etc.) and converts them into, for example easily, readable reports and user-friendly dashboards (Business Intelligence). Because it is done fully automatically the whole process is incomparably faster and more efficient than manual collecting and analyzing an enormous amount of information. Summing up - depending on the input Data Warehouse in result will give appropriate, required output.

Examples of Data Warehouses

Financial Dashboard

Imagine you’re a Chief Financial Officer (CFO) at one of the biggest chemical companies in Poland (Europe top 5). Your responsibility, among others, is to manage company financial risk, keep an eye on cash flow forecasts and present financial status of the organisation to other board members and CEO.

These tasks require collecting, transforming and processing vast amounts of information from sources like SAP ERP system, multiple bank accounts, custom financial Excel reports and others. What is crucial - it’s essential to have all this information up to date at any time.

Financial Dashboard

We’ve faced this challenge during implementation of a Data Warehouse enriched with stack of analytical applications fulfilling those needs. Beyond standard Data Warehouse ETL processes implementation and custom management dashboards, we have delivered more sophisticated applications like real time currency risk alerting and forecasting (by calculating currency gaps & value at risk).

Core business value delivered with FDB:

  • always up to date financial liquidity forecasts
  • visually appealing financial KPIs presentation
  • integration of all information essential for decision makers
  • automation of reporting processes and saving time of core employees

Though the costs of implementing Data Warehouse of such scale are high, they are usually well justified by the insights the tools can generate, time saving and increased performance of the whole financial department. That’s why many CFOs consider digitalization of financial forecasting and ask us for help during this process.

SportClub Group

At first glance this system, which supports the work of call center operators, does not look like a Data Warehouse project. It looks just like some useful tool with familiar and intuitive UI/UX, intended for employees of the company.

But in order to deliver the value it needs to be integrated, in real-time with 7 different e-commerce shops (based on IAI platform). This is where Data Warehouse comes in - such integration requires processing large amounts of data and lots of queries in a tremendous speed. As a result, the system provides the employees with essential data about customers who are contacting the call-center.

SportClub Data Warehouse

Before the implementation of Data Warehouse in SportClub Group, identification of the customer and his/her order was taking a few minutes before the call-center operator could even start to solve the problem or answer any questions.

After the implementation of DW, the whole process is sped up significantly which transfers directly into higher efficiency of SportClub customer service.

SportClub DW contains:

  • Data integration from many sources with thousands of queries
  • Real-time customer recognition (by a phone number)
  • Customer profile - last orders, payments etc.
  • Customer buying patterns - what products does he/she usually buy
  • Customer rating system - whether he/she is polite or not for the operators :)
