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. Need more specifics visit http://www.oracle.com/rdb Regards, Murali Vallath Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> Date: Thu, 16 May 2002 18:58:24 -0800 Hello, What are the differences between the two?
