Automatic Notification of New DB Entries

Background: I'm assisting a friend whose organization is coming onto the Net. Key applications is a full-text database which we will available to 'net and other users. (A Z39.50 implementation is certainly a natural here, and we're considering that.) Point at hand: We're considering supporting 'standing' search requests as a service to users. Such requests would be run against new/arriving documents as these enter the data base. Matches would result in automatically-generated e-mail to the interested party, with notification of title, author, keywords/subjects matched, etc. Problem: But running each standing query against each new record/document would be a real machine-eater, and we're looking for a better way to accomplish that. Possible solution: We've found a software product, LMDS, that will do this nicely with some moderate integration effort. Question: But there have to be others, and I'm interested in hearing from anyone working this field who might be familiar with the problem and other solutions. E-mail or followup will be appreciated. Thanks, folks. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ashore@access.digex.net | Signature?
