I have several .Net projects that would benefit from using the document / object database, the opposite of relational. I think db4o would be a good choice, but we are not sure how much it costs. I would like to use MongoDB , but the design is not intended for small applications with a single server.
Are there other options that I just did not use for small-scale applications?
EDIT: So this is a space in which there is no good solution? Are there small and long-lived document databases? Would my best choice be to use MongoDB and set the --syncdelay parameter to 1?
