Data Definition Language

data horizon

the span of time within which data of a given type is available
NOTE: For stable long term data, this may be the validity period of the timetable or stop data. For more volatile short term data such as daily operational changes, it may be a shorter operation period such as the day or week. For real-time data this will be the retention period in the system of very volatile data, such as short…

the span of time within which data of a given type is available
NOTE: For stable long term data, this may be the validity period of the timetable or stop data. For more volatile short term data such as daily operational changes, it may be a shorter operation period such as the day or week. For real-time data this will be the retention period in the system of very volatile data, such as short term movement and prediction data, for example an hour, or as soon as the data is obsolete. Systems that keep historic logs of data value may offer a longer data horizon for some types of volatile data.

data managed object

entity that is managed by a DATA ADMINISTRATOR as part of a distributed system of data management of objects with well defined identifiers and data ownership
NOTE 1 to entry: Such objects conform to the abstract DATA MANAGED OBJECT supertype that defines associations and behaviour for data management.

data system

the origin of operational data referring to one single responsibility. References to a data system are useful in an interoperated computer system

the origin of operational data referring to one single responsibility. References to a data system are useful in an interoperated computer system
NOTE: For SIRI, this entails in particular specific systems for assigning unique identifiers to relevant entities such as STOP POINTS or JOURNEYS, about which messages are to be exchanged, and which can be matched to the locally known entities identified by the respective internal operating data. The DATA SYSTEM must be mutually agreed between CLIENT and SERVER. A DATA SYSTEM has both a data model to describe the entities and their relationships, and a Namespace to describe the unambiguous set of identifier values.
