Was ist ein Data Warehouse?
A data warehouse is a digital system that stores data from different data sources and is optimized for performing queries and generating reports. It differs from an operational database in that it uses denormalized schemas and column-based storage. This enables fast queries and the flexible provision of data for business intelligence applications.
A data warehouse solution usually consists of the following components:
- A relational database for storing and managing the data
- An ETL solution for data preparation for analysis
Die BI-Architektur von Data Warehouses
As a rule, the architecture for business intelligence applications consists of three main levels or layers. The structure consists of the database server, analysis engine and front-end client:
- Database server (lowest layer):
This is where data is loaded from transaction systems and external sources. The ETL process is designed in such a way that data is integrated automatically and seamlessly. - Analysis engine (middle layer):
This serves as the analytical layer and is responsible for merging data from the lowest layer. Cross-database queries are executed to provide valuable insights. - Front-end client (top layer):
This layer is responsible for displaying the results. Business analysts use dashboards to view reports and make informed decisions.
Why a data warehouse is indispensable for companies
Data warehousing has many advantages for you as a company. Company size and sector are irrelevant - every company benefits from this investment in the long term. We summarize the most important reasons for using a data warehouse:
