I’ve read this book, but I haven’t remained it here.
The books is https://pragprog.com/book/dblegacy/beyond-legacy-code . The book has Japanese edition. I god interested in this book when the Japanese one appeared in my Twitter’s TL. ( I haven’t bought Japanese edition though )
The book includes tips to evolve software products from small to large. Our product, especially startup, starts small software to large and complicated one. Then, we usually must continue to re-design the architecture to fit each phase. This evolution exists this legacy.
This topic is similar to a book, “Re-Enginnering Legacy Software” I read before.
