Erdus - a universal ER diagram converter: challenges in schema migration
https://www.reddit.com/r/programming/comments/1n9ahbn/erdus_a_universal_er_diagram_converter_challenges/

<!-- SC_OFF -->I’ve been working on a universal ER diagram converter and wanted to share some of the technical challenges I ran into. The project (Erdus) converts ERDPlus (old & new), SQL, and Prisma schemas bidirectionally while preserving relationships, composite foreign keys, and even diagram layout. Some interesting problems I had to solve:
- Deterministic ID generation to keep references consistent across conversions.
- Mapping composite keys and reconstructing relationships without losing integrity.
- Keeping visual positions intact when moving between formats.
- Designing an intermediate representation (IR) strict enough to support round-trip conversions. Here’s the repo if you’d like to dive into the code: https://github.com/tobiager/Erdus Curious how others have tackled similar schema conversion or migration problems. <!-- SC_ON --> submitted by /u/tobiager (https://www.reddit.com/user/tobiager)

I just want to know if there are more people thinking that SOLID is overrated and sometimes add unnecessary complexity
https://www.reddit.com/r/programming/comments/1n9ak7g/i_just_want_to_know_if_there_are_more_people/

<!-- SC_OFF -->I think SOLID it could be good, however try to follows strictly SOLID principles can easily become a problem. I have been working in software industry for around 15 years. I remember one time when I had to debug old code that abuse so much about using inheritance/interfaces. There was around 8 levels of inheritance/interfaces, all clases are almos empty with only skeleton just to support next class, at the end the source file that made the magic was only a simple division, something like double myVal=a/b; I'm pretty sure that was donde because original team did it just to "prepare" code for the future, but the truth is that only brings more problem that solutions <!-- SC_ON --> submitted by /u/-WhiteMouse- (https://www.reddit.com/user/-WhiteMouse-)
