Frequently Asked Questions


The major design objectives for the CERIF 2000 data model were to develop:

  • a full CRIS data model with flexibility to allow the majority of existing CRIS to accommodate their own databases structures;
  • a base framework for data exchange.

These objectives have been met by:

  • defining a full CRIS data model which will cover the database structures of the majority of existing CRIS
  • defining a set of data models that could provide examples for data exchange (since there are an infinity of possible exchange data models between CRIS). These examples of data models also illustrate that it is not necessary to implement the full CRIS data model if the requirement is for only a particular subset;
  • defining a metadata data model to provide a uniform summary-level view over heterogeneous information sources.

Subject indexing is essential in the case of access to multiple data sets from multiple sources and in multiple languages. This is the case for the CERIF 2000 environment. Specific thesauri and classifications have been recommended for research subject ( Ortelius ), economic activity ( NACE ) and products ( CPA ). Other indexing guidelines have been given for controlled value lists for specific attributes.

Examples of CERIF 2000 Full Data Model implementations in a selection of Data Base Management Systems

You may download three examples of implementations of the full CERIF 2000 Data Model from here (in Oracle Version 7 and MS SQL Server as SQL scripts and as an Access database file). These examples are available as an illustration of the CERIF Data Model guidelines. Note that these models are being delivered "AS IS" and the European Commission makes no warranty or guarantee as to its use or performance. Users may use them at their own risk.
