  • Describe at a high level the java persistence api and object-relational mapping it entails
    Describe jpa entities and describe how to create an entity class
    Describe entity mapping and the role of a primary key in mapping, describe how to change default mapping, and use temporal types and transient fields
    Describe the data types for fields and properties and contrast persistent fields and properties
    Describe the role of the entity manager with an example of its use in a java ee application, and describe the entity instance life cycle and entity manager methods
  • Describe persistence units and persistence contexts in java ee applications
    Describe how to perform crud operations with entities
    Describe how to create queries with the java persistence query language (jpql)
    Apply jpa to a java ee application
