In the course Java Data Access with JPA Object Relational Mapping with the Java Persistence API 2.x is on the agenda.
After an overview of the data access capabilities in Java, including JDBC, and the challenge they face, the basic concepts and architecture of the JPA is explained. The role of the Entity Manager and the persistence.xml configuration file is discussed.
The next topic covers the concept of a JPA Entity, the lifecycle of Entities and how Entity classes are mapped to database tables. Also the various states Entities can have in relation to the database such as new, persistent, detached and removed are discussed in this respect as is the concept of merging.
Furthermore the use of annotations and XML mapping files and the role the various properties and attributes play is explained.
The various key generation strategies are discussed as well as the mapping of association relationships and the mapping of inheritance relationships between Entities. Next the possibilities of the JPA Query language, JPQL, are covered and the uses of JPA criteria and native SQL queries.
The function and operation of Entity callbacks that are called immediately before and after the execution of a persistence operation is explained and the alternative use of Entity Listener classes as well.
Part of the course program is also the treatment of interceptors which are used for crosscutting concerns like logging and security. Finally, attention is paid to the use of JPA in a Java EE application, how to interact with EJBs and the method of packaging JPA entities.
Finally JPA transactions are addressed in both a desktop environment and a Java EE environment.
Experienced Java developers who want to learn how to use the Java Persistence API for accessing data in databases.
Experience with Java programming and object orientation is required to participate in this course. Knowledge of database structures and SQL is beneficial for a good understanding.
The concepts are treated on the basis of presentation slides and demos. The theory is interspersed with exercises. All topics in the Java EE Persistence API Developer Certified Expert Exam (1Z0-898) will be discussed. The course material is in English. The course times are from 9.30 up and to 16.30.
Participants receive an official certificate Java Data Access with Persistence API after successful completion of the course.
