What is the relationship between SDO & JAXB?
JAXB is a Java Community Process (JCP) standard and stands for Java API for XML Data Binding. As an XML binding framework for the Java language, JAXB performs marshalling/serializing (Java to XML) and unmarshalling/deserializing (XML to Java). SDO defines a Java binding framework of its own and it goes one step further. While JAXB is only focused on a Java-to-XML binding, XML isn’t the only kind of data SDO can bind to. SDO provides uniform access to data of various types through its Data Mediator Service (DMS). Examples of data types include relational databases (RDBs), entity Enterprise Java Beans (EJBs), or XML registries. SDO also offers both a static and dynamic API, whereas JAXB only provides a static binding.
