Termination of providing SRS(Sequence Retrieval System) services

DDBJ terminates providing SRS services (by WWW and WABI ) as of the December 26, 2008. We appreciate very much that you have used SRS since it was firstly launched in DDBJ in 1999. We apologize for your labor switching your keyword search system from SRS to ARSA, but, we hope ARSA is useful for all DDBJ users. Please refer the summary of ARSA and SRS shown in below.

(1)ARSA and SRS Search functions

SearchEngine High-speed XML database search engine "Interstage Shunsaku" was applied for the nucleotide sequence database retrieval Keyword search system developed by EBI(European Bioinformatics Institute) was applied and reconstructed for the DDBJ database retrieval
Key Features
  • Rapid response: Even in any complex search keys, the results are returned within 5 seconds
  • In the DDBJ database retrieval, any combination of feature/qualifiers used in the DDBJ flat file format can be specified as search keys
  • Wide variety of WEB API programs such as SOAP/REST is applicable
  • From Quick Search (simple keyword search) to Advanced Search (specify a complex search queries), multistage search condition can be selectable.
  • Wide variety of WEB API programs such as SOAP/REST is applicable

functions ARSA SRS
Cross search of multiple DB Yes Yes
Specifying the search field Yes Yes
Use of DDBJ flat file Feature/Qualifier Yes No
Quick search Yes Yes
Multiple keywords connection using and/or/not Yes Yes
Relation to analysis tools Yes Yes
Speed fast slow

:Use of "not" in Quick Search is in being enhanced (as of Aug. 2008)

(2)ARSA Improvement History

    No. of
2004.12 Trial operation started at the DDBJ HP
"DDBJ" and "DDBJNEW" only
2005.12 Upgraded
Full-time operation started
2007.02 21DBs other than DDBJ was added  23 
2007.07 Extensive Enhancement and transfer to Official Operation
<Main New Functions>
  • The search results can be downloaded across databases
  • Change of the displayed items in the result view screen is possible
  • API(Application Program Interface) for Java/Perl was enhanced
2007.10 DDBJ HP design renewal
(ARSA is available at the search window of DDBJ HP)
2007.10 Sequence search program linked to TX Search was changed from SRS to ARSA  
2007.11 Further Upgrade subsequent to enhancement conductted in July"
<Main new functions>
  • Addition of KEGG Pathway Database
  • Specification of detailed search conditions in the all databases, as well as DDBJ
  • Cross search by the common search queries
2008.05 Removal of redundant DBs
4DBs related to PFAM were removed

(3)Usage of ARSA and SRS

In the Page View count, ARSA exceeded SRS in March, 2008.

Unique User:a number of an individual that has visited a Web site or received specific content,for a specified period of time such as a day or month. More than one time visits by the same user is counted as 1.
Page View:a request to load a single page of an Internet site. This number is widely used as an access index to the site

(4) Conclusion
DDBJ, since starting the ARSA services in December of 2004 as a trial operation, has built up continuous improvements for the more convenient keyword search system. Meanwhile, DDBJ has introduced ARSA at the scientific meeting and DDBJing tutorials. The increase of ARSA users reflects these efforts, and as a result, DDBJ decided to terminate providing SRS service.
DDBJ will do all the more efforts for the development of ARSA. If you have any comments for ARSA, please send it from "Your Comment" which is located in the upper blue zone.
