development.

SDE-NB provides a unified modeling environment with NetBeans, not only the

Modeling and CRC Card Support, but also the modeling features such as a
series of UML diagrams which truly conform to the latest UML 2.0
notations. SDE-NB also provides the full round-trip code generation and
code reverse engineering functions. SDE-NB being integrated to NetBeans
reduces the efforts in all phases of the software development life cycle.
