Maybe I am searching for the wrong keywords but I could not find any information on whether it is possible to save persisted objects to files...

I have a business application that is locally installed and uses hibernate to save its actual state. It would be nice not only to store the persisted obects in a database but also save them to a local file. Doing so would make the update process of the application safer (as the database can be completely replaced) and offer the possibility to share data between users on the network (a dedicated database server is no option for security reasons).
I think it should be possible to save the state of the database with simple Insert-Statements in a text-file, but can find no reference to a working solution (or even the thought to do so).

Do i have any misconception in my thinking? Any thought on this or hint to lead me to a new understanding is highly appreciated.

Hibernate is an Object/Relation Mapper, so your entities will be mapped to database tables. There is no need to store entities to files when you can use a lightweight database like HSQLDB which has disk persistence as well. All in all, your entities are basically stored in some files on disk, just that in a compacted binary form.

Because of the ACID guarantees, SQL capabilities, Indexing options, and in-memory buffer optimizations, a database is way more suitable than a plain text file even for trivial tasks.

You can also use JSON, and, this way, your Domain Model is not strictly tied to a fixed schema.

Thank you for your answer, I will definitely have a look at JSON and the link you provided. It seems to be what I want, a way to interchange persisted data from one local application that uses hibernate to another.
