There are several reasons to set up this system, such as, to acknowledge technological resource distribution and using nationwide, to set up a technological resource database, to set up a updating system for dynamic technological resource data, and to form an initial national basic technological resource management system, etc. Because of the diversity of data, and the plexity while judging the data’s type and validity, it is decided to adopt “Ajax”, which is good at asynchronous munication, to improve the security and convenience of resource filling. In order to fulfill the need of “Information Management System of Resource Investigation of The National Science and Technology Infrastructure Platform”, the system uses “GWT” as the frame of the system, and “EXT” as performance of interface. And it also adopts B/S for structure, RPC and JSON for transmission. Function: resource filling and searching, news press, news exhibiting, customer .
