Hi everyone,
I’m looking for guidance on how others handle versioned business logic in Oracle-based systems, especially when applications evolve over time and older logic still needs to be supported.
In my case, requirements change gradually—new rules are introduced while existing processes must continue working for historical data. I’m trying to balance maintainability with performance, without ending up with overly complex PL/SQL or tightly coupled application logic.
From my experience working with structured system workflows (including projects I work on through my brand Funnelsflex), I’ve found that clear separation and long-term structure matter more than quick fixes—but I’m curious how this is typically handled in Oracle environments.
Some specific questions:
- Is it better to manage versioning at the database layer (packages, views, conditional logic) or push this entirely to the application layer?
- How do you avoid logic duplication while still supporting older behavior?
- Are there any Oracle-recommended patterns or real-world practices for this scenario?
I’d appreciate hearing how others have approached this in production systems.
Thanks in advance for your insights.
