One of the major challenges facing scientists dealing with gene expression data is how to integrate, explore and analyze vast quantities of related data, often residing in multiple heterogeneous data repositories. In this paper we describe the problems involved in managing gene expression data and discuss how these problems have been addressed in the context of Gene Logic's GeneExpress system. The GeneExpress system provides support for the integration of gene expression, gene annotation and sample (clinical) data with various degrees of heterogeneity, and for effective exploration of these data.
