A proxy that aims at satisfying multiple customized client profiles will face a scalability challenge in trying to maximize the number of clients served while at the same time fully satisfying complex client needs. In this paper, we introduce an abstraction of complex execution intervals, a combination of time intervals and information streams, to capture complex client needs. Given some budgetary constraints (e.g., bandwidth), we present offline algorithmic solutions for the problem of maximizing completeness of capturing complex profiles.}, keywords = {Bandwidth, complex client information need, Data Delivery, Data engineering, database management systems, Educational institutions, Internet, Mashups, mashups generation, Monitoring, multiple information source, offline algorithmic solution, Portals, PROBES, Profiles, Query processing, scalability, scheduling, volatile information stream, Web 2.0, Web Monitoring}, isbn = {978-1-4244-3422-0}, doi = {10.1109/ICDE.2009.204}, author = {Roitman,H. and Gal,A. and Raschid, Louiqa} }
