To achieve flexibility, real-time capabilities, and reliable performance, the following design patterns can be used:
1. Event-Driven Architecture
Event-driven architecture is chosen because it allows the system to react instantly to changes, like inventory updates or sales transactions.
➡️ Tools like Apache Kafka or RabbitMQ are ideal for handling event queues and processing them reliably.
➡️ This approach ensures no delays or mismatches in inventory data.
2. CQRS (Command Query Responsibility Segregation)
CQRS is used to separate how data is written and read.
Writing involves updating inventory when stock is added or sold, while reading involves generating reports, such as sales trends or current stock levels.
➡️ The separation ensures that high-speed updates do not interfere with complex queries, like calculating total inventory value across stores.
➡️ This pattern enhances system responsiveness, especially during peak loads.
