There is no connection between her work on active database (mostly the "starburst" prohect in IBM Almaden Research Center) - which focused on adding rules to databases, and the work on streams which focused on continouous queries - a totally different solution. It is also interesting to note that the stream papers don't cite active database papers. cheers, Opher Jennifer Widom was indeed active in the active database community, and at later phase in life she started the stream project in Stanford, she also done some other things before and after these works.

Lets see. Jennifer Widom was active in active DBs. Dont know if the Coral8 people would entirely agree with Opher. Lets see. Jennifer Widom was active in active DBs.
