Health Level 7
Health Level 7 (HL7) is a group of international standards that facilitate the exchange of data between computer systems used by healthcare organizations. The term HL7 is used to refer to both the organization responsible for developing and supporting these standards, as well as to the versions 2.x and 3 of the standards, along with other standards developed by local HL7 organizations across more than 35 countries. The number 7 in the HL7 name corresponds to layer 7 of the ISO/OSI reference model for communication (ISO7498-1), signifying that the standard specifies communication at the application level.

Helm Chart
A Helm chart is a collection of pre-configured Kubernetes resources that can be easily managed and deployed with the Helm tool. Charts offer a reproducible and shareable way of creating Kubernetes applications, ranging from simple resources like a memcached Pod to more complex stacks comprising HTTP servers, databases, caches, and more.

Horizontal Pod Autoscaler
Horizontal Pod Autoscaler (HPA) is a Kubernetes API resource that automatically adjusts the number of replicas of a Pod based on targeted CPU utilization or custom metric targets. HPA is usually utilized with ReplicationControllers, Deployments, or ReplicaSets, and cannot be applied to objects that cannot be scaled, such as DaemonSets.

HostAliases
HostAliases is a Kubernetes feature that allows a user to define a mapping between IP addresses and hostnames that should be added to a Pod's /etc/hosts file. It is a configurable option that can be used to inject custom host-to-IP mappings into the container's networking namespace. However, this feature is not supported on Pods that are using the hostNetwork mode.

HUBS
Gaia-X Hubs serve as national-level organizations that provide a platform for users to participate in the development of digital ecosystems. They facilitate collaboration among national initiatives, act as central contact points for interested parties, and promote the exchange of ideas and best practices with other regional Gaia-X Hubs in Europe and beyond. The Hubs also work towards international alignment by identifying regulatory challenges and defining requirements for a harmonized digital environment.

Hyprid OLAP
There are various techniques for storing multidimensional data structures, also known as OLAP cubes. These techniques include Multidimensional OLAP (MOLAP), Relational OLAP (ROLAP), and Hybrid OLAP (HOLAP). In the hybrid OLAP approach, HOLAP, data is stored partially in the database server and partially in the OLAP server.
