For several years now, the PRISMA project has been renewing the IT systems of the operations centers of DB Netz AG with the aim of creating an IT system for the network-wide rail traffic dispatching with modern software components.
A sub-component of this overall project is a central infrastructure database that is process-wise integrated into the existing distributed IT landscape, merges work and data flows and provides aggregated, network-wide databases, ensures consistency and brings processes together transparently.
The subcomponent (BaSIs-BZ / LeiDa-D) of the overall PRISMA project is largely designed, implemented, tested and put into operation by VIA Consulting & Development GmbH.
