JChem cartridge database

I see from the documentation that the JChem cartridge requires Oracle.  Has there ever been a version of the JChem cartridge for other databases?  I'm specifically interested in PostgreSQL.

Thanks in advance,

Bob

Hi Bob,

We've only ever had cartridge for Oracle.

I'm not sure about the long term plans (my colleagues may comment on this), but it's a lot of effort to develop and maintain yet an other cartridge.

However JChemBase (JCB) supports about 10 different RDBMS, including PostgreSQL.

The Cartridge is really "just" a wrapper around the JCB engine.

It is usually needed for the following reasons:

1. non-Java programming environments

2. indexing molecule columns in existing database structure

(usually needed when replacing an other cartridge)

3. centralizing computations and Structure Cache 

Which one would describe your needs ?

We have alternative solutions for #1 and #3 , e.g. .NET API and Web Services (SOAP).

So if #2 is not a must, you might consider using JChem Base.  

In certain cases you might even get better performance from JCB (less overhead).
