Not required. MV is an alternative replication mechanism to streams.
To use streams
- should have archived log-ing enabled
- You can define table level rules that replicates only a single table.

Hi Dear,
   The requirement that you want to achieve is also possible through Materialized View.That is much easier and simple instead of maintaining Streams..
 For MV
    1. you will create Database link for both database.  e.g.
         Create DATABASE LINK ABC  CONNECT TO userName IDENTIFIED BY Password USING 'tnsEntry'
(where tnsentry is the DB Alias in Tnsnames.ora)
 
    2.  then create a MV  in Destination DB that gets data from Source DB.
    3.Then create a trigger on the Materialized View that will insert MV data in a Table (Backup)


Thanx

Streams is not compulsory.  In fact, while I do like Streams for many, many things, and have implemented in in some very large environments, in your case I would use MViews instead.  Even in 10.2 Oracle has many problems with Streams.  For more (definitive) information on anything Oracle, go to technet.oracle.com.

MVs doesnt provide a real-time replication. You have to use streams for such cases.
The data will always be stale upto the last refresh. Once the db is running in archived log mode, its not a problem replicating a few tables.

In case of MVs.
