# Implementation of CQRS/ES system using Axon framework

CQRS is an architecture model that separates models for reading and writing data. It is an architectural pattern that separates responsibility for issuing /commands (performing actions) and querying data/queries (obtaining information). This separation allows developers to optimize each side independently. CQRS is often used in conjunction with other architectural designs, such as Event Sourcing, to create scalable and resilient applications that can process large volumes of data. Watch the video from the event, where Richard Bouška (CTO) and Jaroslav Schnaubert (Lead Developer) from the European Digital Hub of ASSIST shared their know-how. What can you expect? 📌 We start from the complete basics. We define CQRS/ES and explain what Command, Query and Event are. 📌 We also delve a little into the details of Event Sourcing. 📌 Let's talk about what needs to be programmed if we decide to build our own CQRS/ES framework in Java and is this a good idea at all? 📌 We will discuss what infrastructure we need for efficient use of CQRS architecture in Java. 📌 We will show you Axon Framework and Axon Server - tools that will allow architects and developers to focus on business logic and not dive into implementation details. The webinar is suitable for solution architects and developers and all those who want to expand their horizons in IT.
