Single schema or multiple schemas

754124Feb 16 2010 — edited Mar 29 2010
Hello

A few years ago I worked on a greenfield project where we were building a system to serve 20 or so different departments with 1200+ users. The approach the existing DBA had taken was to use a single schema for all objects and for all apps. The big advantage I found with this approach was for development, we could have one database and each developer could develop whatever they wanted in their own schema. Name resolution meant that they could override the main copy of whichever object they were working on just by having it in their schema. Unfortunately the project went nowhere and I left after 3 months so I never got to see what issues were raised with the system in production. So I'm wondering, has anyone else taken this approach and if so what would you say are the main things to be wary of? Especially things that aren't a problem when the objects are distributed between multiple schemas.

Thank you in advance

David
