Historically, data warehouses were or can be an expensive, scarce resource. They take months and millions of dollars to setup, and even when in place, they allow only very specific types of analysis.
If you need to ask new questions or process new types of data, you are faced with major development efforts. Business intelligence BI is a process for analyzing data and deriving insights to help businesses make decisions. In an effective BI process, analysts and data scientists discover meaningful hypotheses and can answer them using available data. The cause might be lack of engagement with website content. Within the BI system, analysts can demonstrate if engagement really is hurting conversion, and which content is the root cause.
The tools and technologies that make BI possible take data—stored in files, databases, data warehouses, or even on massive data lakes—and run queries against that data, typically in SQL format. Using the query results, they create reports, dashboards and visualizations to help extract insights from that data. Insights are used by executives, mid-management, and also employees in day-to-day operations for data-driven decisions. A data warehouse is a relational database that aggregates structured data from across an entire organization.
It pulls together data from multiple sources—much of it is typically online transaction processing OLTP data. The data warehouse selects, organizes and aggregates data for efficient comparison and analysis. Data warehouses provide a long-range view of data over time, focusing on data aggregation over transaction volume. The components of a data warehouse include online analytical processing OLAP engines to enable multi-dimensional queries against historical data.
Additional skills for data warehousing staff usually include relational database management and creation of database structures. Business intelligence staff usually must have training in statistics and mathematics, as well as programming logic. The growth in these two solutions is due to the maturity of business technology. As organizations accumulated more transactional data, they needed a way to access that data in a meaningful way. These tools are used to create reports that can identify trends and help to inform sound business decisions.

Modern BI tools offer a lot of different, fast and easy data connectors to make this process smooth and easy by using smart ETL engines in the background. They enable communication between scattered departments and systems that would otherwise stay disparate. From a business point of view, this is a crucial element in creating a successful data-driven decision culture that can eliminate errors, increase productivity, and streamline operations.
You have to collect data in order to be able to manipulate with it. When data is collected through scattered systems, the next step continues in extracting data and loading it to a data warehouse. With an increasing amount of data generated today and the overload on IT departments and professionals, ETL as a service comes as a natural answer to solve complex data requests in various industries.
Secondly, data is conformed to the demanded standard. In other words, this transform step ensures data is clean and prepared to the final stage: loading into a data warehouse.
Now we approach the data warehousing and business intelligence concepts. While both terms are often used interchangeably, there are certain differences that we will focus on to get a more clear picture on this topic. The main differences, as we can also see in the visual, between business intelligence and data warehousing are indicated in these main questions:.
Business intelligence and data warehousing have different goals. While they are connected and cannot function without each other, as mentioned earlier, BI is mainly focused on generating business insights, whether operational or strategic efficiency such as product positioning and pricing to goals, profitability, sales performance, forecasting, strategic directions, and priorities on a broader level.
The point is to access, explore, and analyze measurable aspects of a business. In a nutshell, BI systems and tools make use of data warehouse while data warehouse acts as a foundation for business intelligence. Skillful analysis will try to avoid problems like social and statistical biases, over- and under-fitting, duplicatability failures and self-reference. Good business intelligence usage can ensure that information gets into the hands of decision-makers and powers a data-driven culture.
