DESCRIPTION:*Note the unusual room*\n\n*Abstract:*\n\nDatabase systems hav
 e been designed to manage business\ncritical information and provide this 
 information on request to connected\nclients\, a passive model. Increasing
 ly\, applications need to share information\nactively with clients and/or 
 external systems\, so that they can react\nto relevant information as soon
  as it becomes available. Event-driven architecture\n(EDA) is a software a
 rchitectural pattern that models these\nrequirements based on the producti
 on of\, consumption of\, and reaction\nto events. Publish/subscribe provid
 es a loosely-coupled communication\nparadigm between the components of a s
 ystem\, through many-to-many\,\npush-based event delivery. In this talk\, 
 we describe our work integrating\ndistributed content-based publish/subscr
 ibe functionality into a database\nsystem. We have extended existing datab
 ase technology with new capabilities\nto realise EDA in a reliable\, scala
 ble\, and secure manner. We\ndiscuss the design\, architecture\, and imple
 mentation of PostgreSQL-PS\,\na prototype built on the PostgreSQL open-sou
 rce database system.\n\n*Bio:*\n\nLuis Vargas is a PhD student supervised 
 by Pr. Jean Bacon. His research focuses on possible synergies between data
 base and messaging technologies to share information and coordinate proces
 ses.\n\nHis interests span the areas of databases\, data dissemination\, e
 vent architectures\, and transaction processing.\n\nBefore Cambridge\, he 
 spent a few years at GE Mexico/US as technical leader of funds transfer sy
 stems. He holds a BSc in computer science from ITC\, Mexico and a MSc in D
 istributed Systems from Essex University\, UK.\n\nHe is a member of Jesus 
 College.
