Data consists of different signs which are related to each other ordered by a special Syntax rule. Data are numbers, characters, images, or other outputs from devices. Data are in a format that can be further processed by a human or put into a Computer, stored and processed, andlor transmitted to another human or to an other information processor. Data on its own has no meaning. Only if interpreted by some kind of data processing system does it takes on meaning and become information.

Raw, unrelated numbers or entries, explicated on a medium (e.g., in a database). Data are numbers, characters, images, or other outputs from devices.

Information is data in a context. Information can be persistent (contained in an information system) or virtuai (deducted from persistent information)

Information is data in a context and can be explicated and stored in an information system.

Information Architecture combines interface design, interaction design and virtual reality to create digital structures which allow for representational, navigational, or exploratory tasks.

Information architecture (Wurman, 1996) is a field of graphic design, interface design, interaction design, and human-computer interaction. In contrast to information design, the field of information architecture concentrates more on structural rather than presentational issues.

Information design is the art and science of preparing information so that information is comprehensible, rapidly, and accurately retrievable, and easy to translate into actions.

Information Design ist das Handwerk und die Wissenschaft, Information so aufzubereiten, dass diese schnell und genau verstanden werden kann.

Information visualization is the use of computer-supported methods to interactively explore and derive new insights through the visualization of large sets of information.

Information visualization is the use of computer-supported methods to interactively explore and derive new insights through the visualization of large sets of information (Card, et al., 1999).

Information visualization is the use of computer-supported methods to interactively explore and derive new insights through the visualization of large sets of information.

Information Visualization Forschende untersuchen, wie computerbasierte Visualisierungsmethoden eingesetzt werden können, um grosse Datenbestände mit Hilfe von interaktiven visuellen Benutzeroberflächen zu erforschen, oft in Echtzeit.

Generally speaking, the field of knowledge visualization examines the use of visual representations to improve the creation and transfer of knowledge between at least two people. Knowledge visualization thus designates all graphic means that can be used to construct and convey complex insights. Beyond the mere transport of facts, people who employ knowledge visualization strive to transfer insights, experiences, attitudes, values, expectations, perspectives, opinions and predictions, and this in a way that enables someone else to re-construct, remember and apply these insights correctly.

Knowledge Visualization examines the use of visual representations to improve the transfer and creation of knowledge between at least two persons

We define knowledge visualization as: Knowledge visualization examines the use of visual representations to improve the transfer of knowledge between at least two persons or group of persons.

Knowledge visualization designates all graphic means that can be used to develop or convey insights, experiences, methods, or skills.

Knowledge Visualization in contrast examines the use of visual representations to improve the transfer and creation of knowledge between at least two persons

An externalized visual mean or mental model used to represent information.
