The IUCLID data model consists of two distinct parts:
the static data structure and
the configurable data structure
The static part of the data model is used to store data on the following IUCLID data sections:
Legal entities
Sites
Reference substances
Substances (section 0.1 - 3.9)
Mixtures ( section 0.1-3.10)
Templates (header only)
Dossiers ( header only)
Categories
Annotations
The data structure of this part of the data model is considered static because it cannot be adapted by a simple configuration step (to be executed centrally by the IUCLID Management Group). Any change to the data model (new fields, new data types etc.) would necessitate a new roll-out of IUCLID.
The static part was introduced because the simplification in terms of performance and management clearly offset the more complicated business of one day updating the relatively stable data model.
The configurable part of the data model is used to store data on the following IUCLID data sections:
Endpoint study records (i.e. section 4 - 10)
Endpoint summary records (i.e. section 4 - 10)
Additional information (i.e. section 11 - 13)
The advantage of the configurable sections is that data model modifications like the following are simple configuration steps (to be executed by the IUCLID Management Group):
Adding data entry fields
Adding new sections
Extending picklists
Adding new Dossier templates
Such data model modifications can be published and distributed by the IUCLID Management Group as Plug-ins. Once a new configuration plug-has been activated in a IUCLID installation, the extended data structure is available. No full-scale new deployment and roll-out is needed.
