      Project Overview

      Developments in our ability to integrate and analyse data held in existing heterogeneous data resources can lead to an increase in our understanding of biological function at all levels. However, correlating data from different data resources is still difficult. To address this, we are building upon advanced database technology to develop a mediator which will integrate access to heterogeneous, distributed biological databases, while making use of existing search engines and indexes, without infringing on the autonomy of the underlying databases. To make it easier for scientists to access these data resources, we are developing a network user-interface to facilitate multi-database querying.

      Our integration techniques have potential for use with a wide variety of databases. However, we have particular interest in using them to support our protein modelling work, particularly modelling proteins of the immune system. In this, we can make use of data stored locally on antibody sequences and structures, and related data held at other sites. A particular strength of our use of object-oriented technology is the ability to combine computation with data retrieval. In the context of homology modelling, this means that fitting and transformation operations implemented as database methods can be applied directly to objects representing molecular fragments retrieved from the databases.
