Abstract
Biological information is frequently widespread over the Web and retrieving knowledge in this domain often requires to navigate through several websites. Data sources are usually heterogeneous and present different structures and interfaces. Mediator systems can be used to perform integration of such databases in order to have an integrated view of multiple information sources and to query them. The MOMIS system (Mediator envirOnment for Multiple Information Sources) is a framework developed by the Database Group of the University of Modena and Reggio Emilia (www.dbgroup.unimo.it) to perform intelligent information integration from both structured and unstructured data sources. The result of the integration process is a Global Virtual View (GVV) of the underlying sources which is a conceptualization of the underlying domain and then may be thought of as an ontology describing the involved sources. Queries can be posed over the GVV regardless of the structure of the local sources in a transparent way for the user. The MOMIS system has been experimented for the realization of the CEREALAB database. CEREALAB is a research project of technology transfer for applying Marker Assisted Selection (MAS) techniques to cereal breeding in Italian seed companies.
