Area 1: ER-2-XML
 Convert ER Schemas to XML Schemas
 Ideas :
 Extend ER Model to capture more semantics
 Map extended ER Model into an XML schema
 Retrieve data from database
 Return result in XML
 Status: initial tool implemented by prior MQP
team and available for download.
 Paper : published in XSym’04.
4
Area 2: Updating XML Views of
Relational Databases
 CoT defines a specific XML View over RDB
 Tasks :
 Study how to translate updates specified over such views
 Develop simple translations for insert, delete and modify\
 Status: Prior MQP team has worked on this, more cases
can be added.

CAPE : Engine for Querying
and Monitoring Streaming Data
Example of Stream Data Applications:
• Market Analysis
–Streams of Stock Exchange Data
• Critical Care
–Streams of Vital Sign Measurements
• Physical Plant Monitoring
–Streams of Environmental Readings

MQP Projects in CAPE
 Develop new services for core engine:
 Scheduler of query flow graphs
 Data shedder under fluctuating loads
 Distributed query processing
 Develop stream applications
 e.g.: TRAFFIC, SENSORS, HEALTH, …
 Load real data streams : traffic simulation
 Develop useful queries, like “average density in city
region X over last 5 minute window”
 Provide usable GUI and visual result for monitoring
10
TotalETL MQP Projects
 General: Data warehousing and collaboration
workflow management tool suites
 Current MQP Project: Developed a collaboration
server, complete with session manager, project
manager, job scheduler, and project repository.
 Proposed MQP Projects:
 Extend collaboration server to support scalable project
execution by utilizing cluster of machines, java concurrent
thread libraries for parallel project flows, better scheduling.
 Develop client (GUI) that enables users to collaborative
develop ‘projects’, as well as administrator GUI to monitor
status of project executions.
