The article reviews the COLA framework’s evolution to version 3.0, explaining how the author applied Ockham’s razor to remove unnecessary commands, interceptors, converters, validators and class‑scanning logic, resulting in a leaner, more maintainable Java backend architecture.
This article examines the COLA application‑architecture framework, explains how the author applied Ockham’s razor to prune unnecessary concepts such as Command, Interceptor, and Convertor/Validator/Assembler, and shows concrete code before and after the simplification, culminating in a leaner, more maintainable backend design.
COLA 3.0 removes unnecessary components such as Command, Interceptor, Convertor, Validator, and Assembler, applying Ockham’s razor to simplify the framework, improve readability, and reduce maintenance overhead while preserving essential extension points, illustrating how leaner architecture can enhance Java application development.
