This term refers to the ability of a system to perform a specific task, which may be a production step or operation. The term "adaptability" describes the different ways in which a system can be modified or adjusted to perform a task. There are three main types of adaptability: Reconfiguration: This involves activating a known production module or switching to a different tool to execute a task that has been executed before. In modular production systems, this may involve integrating a temporarily deactivated module or enabling plug and play capabilities. Adaptation: This refers to the ability of a system to perform a task that it has not performed before, but has the physical capability to do so. A solution must be found, often through a problem-solving or learning algorithm, that enables the system to execute the task. Adaptation with system extension: If the system does not have the physical capabilities to perform a task or lacks sufficient capability, an extension of the system may be necessary. This may involve adding a new module or enabling new capabilities through new tooling. It is important to distinguish between the different types of adaptation capabilities, as the scope of the adaptations and the tools required to achieve them vary widely.

Administration shell

The administration shell provides physical and non-physical economic goods (assets) with a standardized, multi-vendor, interoperable digital twin. The uniform format and semantics of the administration shell allow the digital twin to be used across different company boundaries and follow the asset throughout its entire life cycle.

Advanced Analytics

Sophisticated techniques and tools are utilized in advanced analytics, which involve the independent or semi-independent analysis of data or content, exceeding the realm of conventional business intelligence (BI) and enabling the discovery of profound insights, prediction, or suggestion generation. Advanced analytic methodologies encompass data/text mining, machine learning, pattern matching, forecasting, visualization, semantic analysis, sentiment analysis, network and cluster analysis, multivariate statistics, graph analysis, simulation, complex event processing, and neural networks.

Affective Computing

A computing device equipped with the ability to detect and suitably respond to user emotions and other stimuli is what we refer to as affective computing. This capacity enables the device to gather emotional cues from various sources such as facial expressions, posture, gestures, speech, keystrokes force or rhythm, and even temperature changes of the user's hand on the mouse. All of these cues can signify changes in the user's emotional state, which can then be detected and interpreted by the computer. To accomplish this, a built-in camera captures images of the user, and algorithms are used to process the data into meaningful information. Besides, affective computing applications are exploring technologies such as speech recognition and gesture recognition.

Analytical Databases DWH

A database optimized for supporting business intelligence (BI) and analytical applications, usually incorporated in a data warehouse or data mart, is known as an analytic database. An analytic database, also referred to as an analytical database, is a system that is solely for read-only purposes, housing past data on various business metrics like inventory levels and sales performance. It enables business analysts, executives, and other employees to execute queries and generate reports. This database is routinely updated with the most recent transactional data from an organization's operational systems.

Analytics as A Service

AaaS is the delivery of analytical tools and services using web-based technologies, which enables companies to avoid investing in internal hardware infrastructure for their analytics needs.

The process of obfuscating data involves eliminating the traces or digital footprints that could reveal the source of the information to an unauthorized user. Whenever data is transmitted through a network, it leaves behind an electronic trace that can be followed by forensic analysts to identify the sender.

Apache Hadoop

The Apache Hadoop initiative creates open-source programs for dependable, extensible, decentralized computation. The Apache Hadoop software framework offers the ability to process large datasets across computer clusters through basic programming models. Its design enables it to expand from individual servers to thousands of machines that provide local computation and storage. Instead of depending on hardware for reliability, the framework detects and manages failures at the application level, delivering a highly available service on a computer cluster, each of which may be vulnerable to crashes.

API Management

API management refers to the secure and scalable publication, promotion, and oversight of application programming interfaces (APIs). This encompasses the development of resources to support end-users, which serve to define and document the API.

Architecture of Standards 

The Architecture of Standards (AoS) document establishes a goal for Gaia-X by reviewing and consolidating existing standards related to data, sovereignty, and infrastructure components, while also clarifying which standards are endorsed and supported by Gaia-X.

Architecture Principle 

The Architecture Principles establish the fundamental guidelines governing the use and deployment of all IT resources and assets within the Gaia-X initiative. They are the result of a consensus among the various entities involved in the initiative and provide a framework for making future IT-related decisions.

Artificial intelligence

Artificial Intelligence is a domain of computer science focused on exhibiting intelligent behavior in machines, particularly on computers. Machine learning, knowledge-based systems, and robotics are all subcategories of artificial intelligence.

Artificial neural network

Artificial neural networks are statistical models that take inspiration from the workings of biological brains. They are made up of interconnected nodes arranged in multiple layers, with each node containing a function and each connection between nodes carrying a weight to be optimized using deep learning algorithms. The input that reaches a node's function via each connection is adjusted based on its weight.

Augmented Reality

Augmented Reality (AR) is a type of Mixed Reality (MR) that combines the perceived and computer-generated reality, similar to Augmented Virtuality (AV). Unlike Virtual Reality (VR), where the focus is on creating a completely virtual environment, Augmented Reality aims to provide users with additional information that has a direct connection to their real-world experiences.
