Outside of politics and religion, nothing can get the blood rolling in tech folk’s bodies more than a healthy debate on the merits of operating systems, such as Linux vs. Windows vs. Mac. Personally, I’ve never used Mac in a production environment, but I have plenty of experience ...
HBase is an open source, non-relational, distributed database modeled after Google's BigTable and is written in Java. It is developed as part of Apache Software Foundation's Apache Hadoop project and runs on top of HDFS, providing a fault-tolerant way of storing large quantities of sparse data.

Building Our Own Federated Database
We’ve already talked about The Promise and Failure of Federated Databases and Why Don’t We Have Federated Databases. At the end of the second post I concluded that the only real way to solve this problem is to build the federated database ourselves. Before you ask, “Does he ...

Why Don’t We Have Federated Databases?
Federated databases are a dream that have not materialized. The SQL/MED extension to the ANSI/ISO SQL specification is a step in the right direction. In addition, both SQL Server and Oracle have proprietary extensions that make it possible to query external data sources. If all of this technology ...

Data Durability
A friend of mine half-jokingly says that the only reason to put data into a database is to get it back out again. In order to get data out, we need to ensure some kind of durability. Relational databases offer single server durability through write-ahead logging and checkpoint mechanisms. These ...

What I personally feel is a bit more difficult is to understand how much HBase covers and where there are differences (still) compared to the BigTable specification. This post is an ...
