building a reporting database

hi  

i am in the process of trying to firgure out the best way to model a reporting database . the source for the data in this database is a oltp system and i have figured out these three methods are good.
- using aq and dq message processing

• using snapshot replication
• using ro standby databases.

the last one will lag in data since standby database caanot have any archival log applied when opened in read only.  

is there any other good method to do this . my database is on 8.1.7.4  

thanks
sai
