What is the difference between a NoSQL database like HBase and a data warehouse? Doesn’t both store data from disparate sources and formats?
Big Data Community Group
This group will explore emerging BIG DATA pipelines and discuss the potential for developing standard architectures, Application Programming Interfaces (APIs), and languages that will improve interoperability, enable security, and lower the overall cost of BIG DATA solutions.
The BIG DATA community group will also develop tools and methods that will enable: a) trust in BIG DATA solutions; b) standard techniques for operating on BIG DATA, and c) increased education and awareness of accuracy and uncertainties associated with applying emerging techniques to BIG DATA.

HBase and Semantic Integration
We can use HBase as a storage back end for big-data.Can you think of any application areas or scenarios which may require semantic integration of different tables in HBase?(note that the data stored in HBase is not RDF triples and I’am not talking about using HBase as an RDF backend)
How HBase is Column Oriented?
Does HBase fit into column-oriented database(datastore) definition of http://en.wikipedia.org/wiki/Column-oriented_DBMS.If it does; does it mean the keyvalue entries in HFile is stored in a column basis ie all keyvalues of one {column family:column entry} stored together followed ny next {column family:column entry}?
Exposing Data In HBase as RDF
I have written a HBase scanner that converts HBase row entries into RDF.Can anybody suggest a streaming SPRAQL endpoint that can be used to answer SPARQL queries without actually storing the generated RDF representation?
Beyond BigData?
Hi all,
I hope you’re having good weekend.
I wrote this blog post yesterday about the futuroff BigData. It would be great to get your thoughts:
Thanks,
Daniel
