Definition of Substancein the GSBL

• basic for the GSBL data registration rules• agreed upon and fixed• ID properties/fields are still flexible (due to future amendments)

[2] composed Substance / Preparation

ID-Data for Registration

Technical Data Model

• each substance have to be assigned to one of the 3 types• ID-data are the identifier in the GSBL (GSBL-RegNo.)

• some ID-data are mandatory (flexible!)

• registration of chemical structure is possible!

[Pure Substance]

[Composed Substance / Preparation]

[Class]


chemical structure (if available),

name (multiple),

name (m), [producer], components (m), physical condition

name (m), type of class (chemical, legislation, …)

Business Logicfor Registration of Data


REGISTRATION:

• rule-based software

• rules defining possible

• independent of technical data model

• replicable + repeatable registration process

Update• map external data model to ‘GSBL-data model’

• using script procedures (SPL) to map fields automatically

• extendable pool of general SPL procedures (data model independent)

• implemented rules to check registration criteria (typ3 have to fullfill …)

• define rules to improve data quality!

• alternating mandatory fields (e.g. for Eco-toxicological data or flash point)

• harmonise the format to compare possible redundant or false entries

• using standards (text, units, …) for harmonisation

• merge redundant information in the imported file

• check against already registered substances

• create loader-file (format for ORCALE tables; refer to data structure tables,…)

• write (create, delete, merge) data in the GSBL-data base

• create index

Standardised Interface Data Exchange Format

data exchange format:• standardised• used in all data transfers

• internal (modules)• external (data provider)

• platform independent (ASCII)• usable for different data

models• readable by men and machine

FULGOR

• retrieval data base• created from the ‘original’ ORACLE GSBL (2x/a)• index based flat ‘DB’• decentral, distributable on CD • needs no DBMS, no additional license fee

Performance2 physical data structures and formats

ORCALE• production data base • standard relational DBMS with available tools• build, run and maintain the central GSBL• fast, flexible import / export of data• …
