As the amount of pathway information for various organisms is increasing very rapidly, performing various analyses on the full network of pathways for even multiple organisms can be possible and therefore developing an integrated database for storing and analyzing pathway information is becoming a critical issue. Until now analyzing these networks is not easy because of the nature of the existing pathway databases, which are often heterogeneous, incomplete, and/or inconsistent. We presented a database system called SPDBS to solve this problem. However, application-oriented systems like SPDBS have some limitations on the extension and integration of the heterogeneous databases.
In this paper, we extend previous SPDBS into a web service prototype (SPDBSW) where all functions can be serviced on the web environment. The web services include pathway database integration/search, import/export of SBML documents, pathway reconstruction/visualization. SPDBSW has been implemented by the combination SPDBS and external web services such as OLS, KEGG and NCBI. And user can get more confidential and delicate information from KEGG or NCBI through their web services. The system can be extended or modified immediately by replacing its component web services. We provide SPDBSW at the website http://database.chungbuk.ac.kr/SPDBSW.
