Data Information and Management SystemOverview
Production control organizes the workflow for various processing systems generating raw or value-added products.
DIMS supports the production, cataloguing, archiving, ordering and distribution of earth observation products
A cornerstone is the product library which is the source of processing inputand the destination of the processing output. It provides a complete and consistent reference of the configured products.
Based on the product library, order management handles the business process ordering throughout the system.
A unified operating tool supplies interactive monitoring and control of the DIMS components.
User information services provide the user access to DIMS. A WWW-based interface guides the user from directory information via inventory searches to the desired products which can be directly ordered.

DIMS ScopeOverall Requirements
Access to products of related systems (e.g. ENVISAT-PDS, EUMETSAT UMARF/EPS)
Flexible interfacing with processing systems(e.g. ingestion processing, processing on request)
Support of multi-mission data products
Support of complete product and order loop
Support of existing and producible products
Unified solution for distributed sites or institutions
