Analytical Databases
Glossary Page
Analytical databases (often referred to as data warehouses) belong to the class of relational databases. They are optimized for the OLAP25 application scenario, which is characterized by moderately large amounts of data26, extensive support for the SQL query language and a small to moderate number of users. Analytical databases are not new and are often used in conjunction with Hadoop for big data projects.

Sovereign connectivity: Automating access in dataspaces
Sovereign connectivity in dataspaces requires automating network access to ensure security, compliance, and operational scale. In the Data Intelligence Hub, we replace manual firewall updates with a declarative, Kubernetes-native model using Custom Resource Definitions (CRDs). Customers define their allowed IP ranges through a self-service portal, which generates an IpAccessPolicy object representing the desired state. A controller then reconciles this state with the underlying infrastructure, automatically updating Kubernetes Ingress configurations and preventing drift. This architecture ensures auditability, validates inputs before enforcement, and keeps network access aligned with the principles of data sovereignty across multi-tenant environments.
