Data integration. Individual elements d from source databases are translated to their representation in Biozon as per the transformation function T _D . The graph ∑ resulting from integration of these elements has non-redundant objects, serving to merge the data from disparate sources into a cohesive whole. As shown, six records from GenPept, SwissProt BIND and DIP are translated into Biozon graph form. Each record is transformed into a set of objects (e.g. $P_{gp}^1$) and descriptors (e.g. $D_{gp}^1$). Identical proteins from SwissProt and GenPept records, $P_{sp}^1$ and $P_{gp}^1$ respectively, are instantiated as a single non-redundant protein object P¹ on the graph. Similarly, $P_{sp}^2$ and $P_{gp}^2$ are mapped to a single P². As a result, the two interaction objects $I_{bi}^1$ (BIND) and $I_{di}^1$ (DIP) are mapped to the same object I¹.
