Author Topic: Reverse engineer Cassandra into EA (Read 16923 times)

Has anyone reverse engineered a Cassandra NoSQL database into Enterprise Architect? If so, can you provide pointers?

Thx, Dan

I guess that is not possible. The RE supports only the listed DBs and none of them is a NoSQL. You're likely doomed to manually work that out.

As long as you can make an ODBC connection you should be able to reverse engineer any database to EA.
The supported databases are for forward engineering and using as storage for the models.

Can you connect to a NoSQL over ODBC???

Some googling suggests you can: http://www.datastax.com/dev/blog/using-the-datastax-odbc-driver-for-apache-cassandra

Interesting. The German Wikipedia still states that ODBC uses SQL as base language (I just looked). The English one doesn't.

I followed the recommendation regarding using ODBC and downloaded the 32-Bit DataStax Windows 7 driver. I can connect successfully to the Cassandra instance from the Parallels/Win7/EA virtual machine to my Mac.

when I try to "Import DB schema from ODBC" command in Enterprise Architect 12.0.1215, EA pops up a status dialog, starts reading the system catalog and then crashes. No log messages are created.

I didn't find anything in the Forums.
