Space4J | Java persistence

clipped from

Space4J is a simple database system that will let you work with Java Collections in memory.
Instead of having to perform a SQL SELECT to fetch a User from a database table, you can just
access the users map (java.util.Map) and call users.get(id). With Space4J, all your data
is kept in memory inside the JVM. There is no need for an extra database application, a socket connection, a
JDBC driver, a SQL statement or any kind of ORM tool. Your data is just there, in memory, inside the JVM,
inside objects, inside Java maps. What can be faster and more straightforward than that?
