SEM-DTJ-3352: Upon completion of this course, participants should have an understanding of how to use the Java Persistence API to build data-driven applications with the Java SE and Java EE platforms.
|
This course provides the student with knowledge of the Java Persistence API needed to develop and deploy data-driven applications with the Java EE and Java SE platforms. The Java Persistence API is a new persistence API that allows Java SE and Java EE technology developers to model database entities as POJOs (Plain Old Java Objects). Students will gain an understanding of how to program with the Java Persistence API independent of platform, as well as how the Java Persistence API integrates with EJB 3.0 component services to facilitate the development of enterprise applications.

Sun Microsystems
Sun ble grunnlagt med én eneste visjon som drivkraft. En visjon om datamaskiner som kommuniserte med hverandre uansett hvem som hadde laget dem. En visjon om teknikk som arbeider for deg, ikke motarbeider deg. Mens andre utviklet varemerkebeskyttede og proprietære løsninger, fokuserte vi på å hjelpe bedrifter inn i nettverksæraen. Som et resultat av dette er vi blitt dotten i .com. Vi leverer systemer og programvare som oppfyller kravene til skalerbarhet og påliteligheten som er nødvendig for å drive den elektroniske markedsplassen.
