Bioinformatics is the field of science in which biology, computer science, and information technology merge to form a single disci- pline. The ultimate goal of the field is to enable the   discovery of new biological insights as well as to create a global   perspective from which unifying principles in biology can be discerned. At the beginning of   the "genomic   revolution", a bioinformatics concern was the creation and maintenance of a database to   store biolo- gical information, such as nucleotide   and amino acid sequences. Development   of this type of database   involved not only design issues   but the   development of   complex   interfaces whereby researchers could both access existing data as well as submit new or revised data.

Bioinformatics
"The use of computing tools to manage and analyze genomic and molecular biological data."

      It also includes the software that are required for the detailed analysis of the genes and proteins e.g. analysis of gene sequences for restriction sites and regulatory elements, open reading frames, comparison with the genes from other sources, designing of prim- ers for PCR and hybridization studies, construction of three dime- nsional proteins encoded   by them,   delineation of the functional domains etc. Bioinformatics is the essential means of analysis and interpretation large component of genomes. It provides the analy- sis machinery for deriving results from genomics data. As genom- ics data and approaches grow in importance and size, bioinform- atics is playing an increasingly important and central role in biol- ogy research.
