Research on Connection Pool Service for Distributed Heterogeneous Databases in WebGIS

WANG Ji-zhou1,2, LI Cheng-ming2, FU Jun-e3(1.School of Remote Sensing and Information Engineering, Wuhan University,Wuhan 430079; 2.Institute of GIS, Chinese Academy of Surveying and Mapping,Beijing 100039;3.Remote Sensing Center, China Institute of Water Resources and Hydropower Research,Beijing 100038,China)  
Distributed spatial databases will be the main data sources of WebGIS. Connection pool is an efficient strategy for the repeated use of database connection. Based on the analysis of signification of distributed heterogeneous databases and limitation of static connection pool, This paper puts forward the dynamic connection pool service. The service can dynamically respond users' requests and assign database connections. At last the service is implemented based on JDBC.
