The Problem with Traditional State
Most Laravel applications rely on standard CRUD (Create, Read, Update, Delete) architecture. When a user changes their account balance, the old balance in the database is overwritten. But what if you need to know why the balance changed? What if you need to audit the system to find a bug introduced three months ago?
Traditional databases only store current state. They suffer from data amnesia. At Smart Tech Devs, when we build financial ledgers, audit-heavy platforms, or complex enterprise systems, we abandon state-based storage and implement Event Sourcing.
What is Event Sourcing?
Instead of storing the current state of a model, Event Sourcing stores every change that has ever occurred to that model as an immutable sequence of events. The current state is simply calculated by playing all those events from the beginning of time.
