Its easier to store derivatives and synthetic instruments because you aren’t
really constrained by a relational model.
(Derivatives are nothing more than a contract.)

So this is the hardest thing to do… teach someone not to look at the data in
terms of an RDBMs model.
And there aren’t any hard and fast rules…
Lets look at an example.

Thank you for your prompt reply.
In my daily work, I mainly used Oracle DB to build a data warehouse with star

To aid visualizing table structure, you could use Enterprise Architect
Even though HBase cells store BLOBS, quite often these BLOBS are
serialized classes.
In EA classes can appear in table definition as field types.

Yeah. Jean-Marc is right.
You have to think more in terms of a hierarchical model where you’re modeling
records not relationships.
Your model would look like a single ER box per record type.
The HBase schema is very simple. Tables, column families and that’s it for
static structures. Even
Not sure you want to ever do that... Designing an HBase application is far
different from designing an RDBMS one. Not sure those tools fit well here.
What's you're goal? Designing your HBase schema somewhere and then let the
tool generate your HBase tables?

Hi all,
Do you have any tools to manage Data Architecture & Modeling for HBase(
or Phoenix) ? Can we use Powerdesinger or ERWin to do it?
Please give me some advice.
