Introduction to Event Sourcing

Event sourcing is a software architectural pattern that transitions the focus from the current state of an application to the history of events that have led to that state. It stores the sequence of events that occur in the application rather than just the final outcome, allowing for better complexity management and auditing. By using event-sourced techniques, developers can reconstruct the state of an application at any given point in time by replaying the recorded events. This approach not only supports strong data integrity but also enhances capabilities such as undo functionality and temporal queries.
