Mastering Hibernate

Chapter 8. Addressing Architecture

In this chapter, we will discuss how to address architectural constraints for an enterprise application using Hibernate. Every enterprise application follows an architecture, which specifies the software components, such as data models, process models, user interface, and data persistence; and system components such as web servers, application servers, and database management systems. Here, we will see how Hibernate can, in fact, address some architectural requirements and constraints. The following points will be covered in detail:

• Architecture matters
• Transaction management:
  • Local transaction
  • JTA
  • Compensating transaction
• Concurrency:
  • Isolation level
  • Locking
  • Application lock
• Scalability:
  • Clustering
  • Database shards
• Performance ...
