Data Management

DKRZ also runs systems especially for scientific data management services. Data resulting from simulations carried out at DKRZ need to be processed before being delivered to scientific users by means of a relational database management system.

Oracle Database Appliance x3-2 The main tasks of the systems include pre- and post-processing of climate modeling results as well as the worldwide distribution of climate data:

  • Pre-and post-processing with respect to the long-term storage in the CERA climate database or the World Data Center for Climate (WDCC)
  • Storage of essential WDCC data on a parallel file system
  • Integration of data resources into national and international climate data federations
  • Deployment of portal services to the databases

Technically, the data management system is based on several HLRE-3 nodes and a special database server optimized for relational database management systems. Furthermore, virtual machines deploy additional less demanding data management services.
