Conceptual Interfaces between PMS-, BMS- and EMS-Databases (VSS1999/249)
Overview
Background & policy context:
Organizations responsible for the integrated road management system need a respective information system to fulfil their demanding tasks. This system is, among others, based on different databases.
For the respective needs of the different road management domains, besides of the fundamental basic data, partial system's databases are needed for the pavement management - PMS, the bridge management - BMS and the equipment management - EMS. These data bases can be characterized by huge data volumes and different referential systems, as for instance the temporal reference and different spatial reference systems. (Planar and linear spatial reference systems as well as geometric definitions and topological properties.)
Besides of the special data, each partial system's database contains general data that have to be given to other partial systems and further users too. To allow those data to be useful for the other participants, the interfaces between the partial databases must be properly designed and biased.
The common conceptual rules must be respected in the partial system's databases to allow combination of respective data.
Objectives:
General road data in the partial system's road databases, for instance for the pavement management PMS, the bridge management BMS and the equipment management, have to be exchanged between these partial databases and third parties systems. The research projects results shall define the conceptual rules for the spatial, temporal and attributive aspects.
Methodology:
Starting from the study of the various subsystems in use today standing the exchange needs to be recognized. The necessary interfaces between subsystems and between subsystems and basic database are identified and designed conceptually. They are designed open, that is, that the interfaces can be adapted to new needs in a simple way.
