I don't have to worry about the transactional EBS data getting tangled in the data within the warehouse right? Also, are there any security concerns?I dont think so.
I typically use an Appsro (read-only) user when querying EBS data. Will I have the option of using read-only or will I have write access? I ask b/c I read something about this that warned of security risk of overwriting data.Read only is fine, since BI is to see data, unless you implement Write-back functionality there wont be any write(data updates) in db.
