There are lots of databases executing in process context:
SQLite, Firebird, H2, HSQLDB, good old (or bad old depending on view)
Access.

Rdb uniqueness is:
- it supports both executing in process context (embedded SQL,
   SQL modules, JDBC native driver) and executing in separate
   server (JDBC thin driver, SQL Services API, ODBC)
- even when executing in process context there are still some
   central administrative processes running
- it is geared towards large usage while traditional embedded
   databases are really geared towards small usage or test
