Hadoop/RDBMS integration: Aster SQL-H and Hadapt

Two of the more interesting approaches for integrating Hadoop and MapReduce with relational DBMS come from my clients at Teradata Aster (via SQL/MR and SQL-H) and Hadapt. In both cases, the story starts:

Of course, there are plenty of differences. Those start:

As for use cases — for starters, please note that a large fraction of analytic inquiries are ultimately about people. And when you’re looking at people, there are a whole lot of data sources you can consult. Many are clearly relational; increasingly, however, some are not. What’s more, people are hard to assess and understand, so you may want to take multiple tries at refining your analysis.

So right there you have an argument for flexible investigative or iterative analytics, over multi-structured (and relational) data. And if you think about how to combine information from all those data sources — well, it’s likely that SOME of the analytic steps will be a lot like joins.

That sure sounds like Hadoop/RDBMS integration to me.
