....data is publicly available, for all intents and purposes the difficulty of using it makes it inaccessible to the scientist. This situation must change. The need for a more structured approach to data management has lead to several ongoing research and development efforts in bioinformatics (e.g. [1] [2] This work was performed under the auspices of the U.S. Department of Energy by University of California Lawrence Livermore National Laboratory under contract No. W 7405 ENG 48. UCRL JC 138042. 2 There is a growing expectation in the community that the relationship between experimental and ....

....mediator approach as described in this work, and the majority is based on materialisation with the known problems of data actuality. SRS ( 3] offers comfortable keyword search mechanisms in a set of locally installed flat files but does not support structured queries or distributed sources. OPM ([2]) is a multidatabase query language without a uniform federated schema. On the other hand, there are numerous research projects in computer science that are based on query mediation (see [4] for a survey) Our system was mainly influenced by the Information Manifold ( 9] which introduced the ....
