Subject FW: [Fwd: Re: Are you happy with Derby?]

Hi Michael,
Your opinion was very encouraging - I also built a prototype based on Derby.
I am happy to say, that our management has almost decided on Derby, subject
to legal approval for the licensing aspects.
We plan to use Derby as an embedded RDBMS in our Network Management
Application. The data stored in Derby will be typical network management
data pertaining to the inventory, fault and performance aspects of network
With this mind, I would like a clarification:
If an external application would like to extract this data for correlation
with the typical customer data, the general way will be to use ij and
proceed. The double booting issue will prevent this. What are all the
possible workarounds for the double booting issue? Can you please give me
the required pointers?
Is there any potential issue when multiple copies of Derby runs in the same
PC (Within the same application or within different applications)?
I appreciate your inputs.

You're asking a Derby list so you're going to get a positive and biased 

response. The short answer is yes.

Derby is really your only option.

With respect to other alternatives, I don't believe MySQL is "free" if

going to embed it in an app for resale.

Of all of the "free" RDBMSs, Derby has the smallest footprint, and since its

derivative of Cloudscape, its already been used and proven in the type of 

application that you're attempting to build. You could use PostGress, but 

again, you're getting a lot of additional features that you really don't

or want.

The only caveat is your "good support" criteria.

"Good Support" is relative. You get what you pay for...

As I said, you're going to get a biased response.

I like others are looking at Derby from a similar perspective.

The only drawback is that Derby is under GPL. So as long as you follow GPL's

rules, you're ok.
