We present a client/server database system with the potential to make all DNA sequences searchable. The database estimated to be approximately 200 Gbps, contains various types of sequences, including WGS and clone reads, draft assemblies, finished sequences, refSeq etc. The search engine will be SSAHA2, a package combined SSAHA (sequence search and alignment by hashing algorithm) with cross_match. Matching seeds of a few kmer words are detected by the SSAHA algorithm. Both query and subject sequences are cut off according to the locations of the matching seeds and then passed to cross_match for full alignment. We aim to develop a platform-independent client/server system which can provide a near real-time (under 10 seconds) search service for a clustered database.
