The (JSD) Network Editor is a CASE tool that supports the Jackson System Development method for designing computer software systems. It can be configured either as a stand-alone product, or as part of the Jackson Workbench suite.
The Network Editor provides an extensive visual interface, which allows JSD specification and implementation network diagrams to be constructed. The (JSP) Structure Editor, can then be used to edit the internal structure of the processes in the network diagrams.
