Hello,

I'm testing NHibernate to see if it will fit our needs.

I've seen that NHibernate could map to a large variety of DBs but not found any file adpater (like xml).

Could someone point me on any information or is that simply impossible ?

I need that to make a persistent snapshot of the datas and haven't any database for that. The other advantage, I can create a lot of snapshots creating files.

I've seen that a session is serializable, but I haven't found how to do it.

Thanks for any help.
Bye,
Didier

NHibernate as distributed is only meant to work with DBMS. Mapping to XML, CSV, etc. is not in the feature set of NHibernate. Having said that, theoretically, anything that has an ADO.NET driver could be used with NHibernate. One may have to extend NHibernate and write his/her own Dialect for the underlying querying language.

Thanks for your answer.

Anyway to serailize the cache ? (all objects)

I don't need to query the file, only to reload it as is.

Thanks
Didier

Hi Didier, NHibernate cannot use XML files as a persistence medium. What you are asking, in other words, is "can I serialize an object graph to an XML file?" Yes, but not with NHibernate; that is not the functional intent of NHibernate.

Google "XML object graph serialization", you will probably find what you need.
