Data modelling for aeronautical data

is the ability of computer systems or software to exchange and make use of information without restrictions.

Therefore the systems must have clear and shared expectations of contents, context and software.

Aeronautical Information Service (paper based)

Aeronautical Information Management (global, integrated data-centric environment)

System Wide Information Management

SWIM basically defines HOW ATM (Air traffic management) Information shall be exchanged in a digital environment.

For this purpose SWIM requires:

• a standardised technical infrastructure

• common service interfaces

• common information exchange models

In SWIM context each ATM domain may have its own, specific data model established:

• AIXM for Aeronautical Data

• FIXM for flight data

• IWXXM for met data

Nonetheless, in a SWIM environment each of these specific data models havs to ensure that it is compliant with a common reference model valid for the wohle ATM Domain.

For this purpose SWIM refers to the AIRM (ATM Information Reference Model)

ATM Information Reference Model

Common reference model valid for the wohle ATM Domain.

AIRM can be seen as the ATM system-wide reference vocabulary for defining ATM information, which also includes a conceptual model of the domain.

Using the AIRM promotes semantic interoperability.

… ensures that the percise meaning of exchanged informatio is preserved and understood by all parties, as it travels through the end-to-end data chain, form the point of origin to the point of destination.

Unified modelling language

• provides a standard way to visualise the design of a system

• enabales the abstract graphical representation of a real-world process, a system or a specific domain

• AISM uses ONLY the class diagramm
