Review of Claremont Report on Database Research
Jiaheng Lu
Renmin University of China
Outline
Five challenges on database research
Database engine revisiting
Declarative programming
Structured and unstructured data
Cloud data management
Mobile application
Our research to meet those challenges
数据库的挑战:Senior database researcher Meeting
Senior database researchers have gathered every few years to assess the state of database research and to mend problems and problem areas deserve additional focus.

Revisiting database engines(1)
Traditional data engine NOT work well
OLTP System: data provenance, schema evolution and versioning
Text indexing
Media delivery
……
Revisiting database engines(2)
Research topics
Remote RAM and flash as persistent media
Treat query optimization and physical data a a unified, adaptive, self-tuning pressing and encrypting data with query optimization
Designing systems that embrace non-relational data models
Declarative programming for Emerging platforms (1)
Data-centric approach for emerging platforms
Manycore chips
Distributed services
puting platforms
…..
Declarative programming for Emerging platforms (2)
Good examples
Map-reduce:
data-parallelism
Ruby, Rails
query-like logic
XQuery
The interplay of structured and unstructured data(1)
Witnessing a growing amount of structured data
Millions of database hidden (Deep Web)
Millions of HTML tables and Mashups
Web Service photo video websites
The interplay of structured and unstructured data(2)
Research challenge:
Extract structured meaning for unstructured data (IR, ML)
Querying and deriving insight from heterogeneous data
Keyword queries
Pay-as-you-go fashion
