Database File Encryption

ObjectDB supports encryption of client-server communication over the network using SSL. Encryption of data in database files is less commonly used, since it slows the database, and when necessary, external encryption is possible (e.g. at the operating system level). Still, this might be useful for some applications. Feature Request Version: 1.04 Priority: Normal Status: Active Replies: 2 Type:  Feature Request ...

can removing an entity throw an exception if the entity is in use?

Suppose you have an entity @Entity class A { ... } and other entities with references to A.   e.g. @Entity class B { A a; // explicit reference to A List<A> list; // list of A's Set<A> set; // set of A's Set untyped; // general collection that may include A's } Objectdb allows me to remove an instance of A, even if a managed B has some reference to that A.

Finance data from SQL Server into ObjectDB daily

Hello -   I think ObjectDB might be just the solution for our current project but I would like some feedback from the community to see if I'm thinking about it right.   We have a finance data mart that is appended to daily via an SSIS package. I would like to pull the data from SQL, add it to a bean and store it in the ObjectDB. This would all happen in an automated fashion. Does this make sense? Is there a way to map the structure of the table directly into ObjectDB from SQL Server?   #1 2011-07-23 20:43 Hello -   I think ObjectDB might be just the solution for our current project but I would li ...
