At @Devoxx , @odrotbohm asked: Are Hexagonal, Onion & Clean Architectures answers to the wrong question? Maybe architecture shouldn’t separate tech from domain but help us focus on the business. 🎥 youtu.be/co3acmgP2Ng 🖼️ speakerdeck.com/olivergierke/d… #DDD #Architecture #Devoxx

The goal here is to preserve the existing ecosystem while gradually converging toward a single, unified query language that can serve relational, non-relational, and higher-level data abstractions under the Jakarta EE umbrella. Read more 👉 lttr.ai/Ajk2D #JakartaEE

Still, the goal is clear: it should be compatible with existing approaches — mapping smoothly to JPQL in Jakarta Persistence and to JDQL in Jakarta Data — while becoming the unified query model that replaces these parallel paths in the future. 👉 lttr.ai/Ajk2C
