Data Representation


AirCERT > Data Representation

The data processed and generated by AirCERT is represented in one of of three formats: in-core, xml, and RDBMS.

Internal Format

When a component is processing or manipulating AirCERT data in a running process, it is likely represented by the libair:: xml:: air_xml_tree_t data structure.

XML

When exchanging data across administrative domains, XML is the preferred representation format. Three different DTDs are used, each targetting different levels of abstraction in the data.

Database

The permanent store for all data is a relational database.
