I remember that Oracle reportedly paid DEC 100 million for the product mainly for the technology a lot of which has subsequently appeared in Oracle RDBMS. To add to the list... log miner I believe has it's roots in Oracle RDB, also locally managed tablespaces. Oracle RDB has managed space in a similar fashion as LMT (not quite the same but same concepts) for probably a decade now.

Oracle has two database products, Oracle RDBMS, (or oracle oracle) and Oracle Rdb. Both of them are relational databases. However, Oracle Rdb only supported on Open VMS.

Oracle purchased Oracle Rdb (previously called DEC Rdb) from Digital equipment corporation several years before. this is a great production and scales pretty well. Many of the large OLTP implementations use Rdb, eg.. Australian Stock Exchange, Korean Stock Exchange, Mercantile Bank, DIRECTV, etc to name a few.

Many of the features you are seeing today with Oracle, existed in Rdb for several years now (partitioning, multi block format) etc. and have moved into the Oracle space from Oracle Rdb after Oracle purchased this product. Actually the cost based optimizer is another good example, and Oracle Expert, new features in Data guard etc.
