Definition: Bioinformatics is defined as the large-scale storage, retrieval and assessment of data from biological studies. This field draws on high-performance computing, software and information technology.
Genomic information is too voluminous for even a large team of researchers to remember or analyze, so the information is placed in complex databases in which the gene and protein structures and functions can be easily accessed, cross-referenced or queried.
Bioinformatics is the application of computer science and information technology to the field of biology and medicine.
Bioinformatics deals with algorithms, databases and information systems, web technologies, artificial intelligence and soft computing, information and computation theory, software engineering, data mining, image processing, modeling and simulation, signal processing, discrete mathematics, control and system theory, circuit theory, and statistics, for generating new knowledge of biology and medicine, and improving and discovering new models of computation (e.g. DNA computing, neural computing, evolutionary computing, immuno-computing, swarm-computing, cellular-computing).
Java, XML, Perl, C, C++, Python, R, SQL and MatLab are the some of the more prominent software technologies used in this field.
