The Hibernate Project is a popular Open-Source DAO implementation for Java Beans based persistence - it automatically produces persistence classes for a chosen data backend such as a MySQL, Oracle, or DB/2 database. XML along with XSLT and POI provide excellent standardized mechanisms to transform that data into useful forms for the end user. AJAX and Web Services allow developers to get that information to other applications in a powerful, flexible, and cross-platform way. JUnit Testing and Template systems such as Velocity and JET provide productivity tools that increase quality and decrease development time significantly. This course is focused around best practices that lead the developer towards a solid foundation so they can exploit MDA/MDD powerfully.
