2 What is Bioinformatics? NIH Biomedical Information Science and Technology Initiative (BISTI) Working Definition (2002) - Research, development, or application of computational tools and approaches for expanding the use of biological, medical, behavioral or health data, including those to acquire, store, organize, archive, analyze, or visualize such data. Bioinformatics is the application of information technology to the analysis, organization and distribution of biological data in order to answer complex biological questions.
