This document discusses JPA value types and the Command Query Responsibility Segregation (CQRS) pattern with case studies. It covers JPA entity types, basic types, embedded types, and collection types. CQRS separates read and write operations by using different models for commands and queries. Case studies demonstrate how CQRS was implemented at companies to improve performance and scalability, such as handling 15,000 transactions per second. Links are provided to additional resources on embedded types, subquery joins, and CQRS case studies.
