More and more Brassica species and relative species from Brassicaceae have been sequenced along the technology improvement of seuquencing and genome assembly. Now, how to apply these bulk genomic datasets to assist the scientific research and breeding work becomes an urgent issue that needs to be addressed. To build functional and user-friendly databases that provide both the basic genome sequences and the elaborately analyzed data, as well as some frequently used tools is one of the solutions. A useful genome database for Brassica crops should have below features. (1) Free access to all the basic datasets, such as the genome and gene annotation files; (2) The common BLAST tool to compare all sequences available for Brassica species; (3) Genome visualization tool to show all kinds of genomic elements in one frame; (4) Well functional annotation of predicted genes for the newly sequenced Brassica genome, it's much better if links of orthologs are made between genes of Brassica and the model plant Arabidopsis thaliana; (5) Information of molecular markers, genetic maps, and population etc. of the Brassica species. In this chapter, we take the database BRAD (http:// brassicadb.org) as an example to introduce the databases in the research field of Brassica.
