Taxonomic databases digitize scientific biodiversity data and provide access to taxonomic data for research. [1] Taxonomic databases vary in breadth of the groups of taxa and geographical space they seek to include, for example: beetles in a defined region, mammals globally, or all described taxa in the tree of life. [2]
Biological taxonomy is not fixed, and opinions about the correct status of taxa at all levels, and their correct placement, are constantly revised as a result of new research. Many aspects of classification remain a matter of scientific judgment. The ITIS database is updated to take account of new research as it becomes available. [citation needed]
The public interface includes both search and browse functions as well as offering multi-lingual services. [2] The Catalogue listed 300,000 species by 2003, 500,000 species by 2005, and over 800,000 species by 2006. [12] As of 2019, the Catalogue listed 1.9 million extant and extinct species. [13]
A taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy.
The Entrez Global Query Cross-Database Search System is used at NCBI for all the major databases such as Nucleotide and Protein Sequences, Protein Structures, PubMed, Taxonomy, Complete Genomes, OMIM, and several others. [9] Entrez is both an indexing and retrieval system having data from various sources for biomedical research.
