KURSINHALT
Persistence is the technique through which object models broker the access and manipulation of information from a relational database. JPA handles the details of how relational data is mapped to Java[tm] objects, and it standardizes Object/Relational mapping. JPA was introduced in Java EE 5, and provided a POJO-based persistence model for Java EE and Java SE applications. JPA has been enhanced in Java EE 6. The Java Persistence API (JPA) version 2.0 specification facilitates more effective and reliable (that is, more strongly typed) methodology for building object-centric criteria-based dynamic database queries.

The Building Database-Driven Applications with Java Persistence API course examines the ins-and-outs of building database applications using the standard Java object-relational-mapping technology, Java Persistence API. This course covers both new features found in the Java Persistence API 2.0, as well as the features found in Java Persistence API 1.0.

In this course you will learn the key concepts found in the Java Persistence API, learn how to create robust entity models, create static and dynamic queries using Java Persistence API Query Language, and learn how to create type-safe queries with the Java Persistence API Criteria API. In addition, the course covers using the Java Persistence API within a stand-alone Java Standard Edition application, as well as within the context of a web-based Java Enterprise Edition application, including using Java Persistence API with the Enterprise JavaBeans[tm] technology.
