Hi everyone,

I am an urban planning PhD student & new to Eclipse. Basically, I am new
to programming too--since it has been like 15 years! The social science
tools I would like to use do not seem to have been invented yet. So, I'm
trying my hand at slowly cobbling a workable system together.

I have several tables of "nodes" and several association tables of "edges"
in an SQL database, which I currently visualize with Graphviz & perl
scripts. I've also used Chisel Group's Shrimp viewer. However, neither of
these rendering tools can be used to continue to build & edit the data.
Because Shrimp is interactive, it does have some analysis potential--but,
to my knowledge, it cannot be used as an editor.

Do I understand correctly that GEF can work with DTP so that--given a
schema and perhaps some details about methods--a GEF diagram can be linked
to an SQL database so that editing the diagram will edit the data? For
example, could I render a network diagram of some subset of my data (via
an SQL query) and then:

1. add box/node (send SQL to create new row in a table of instances)
2. edit box/node attributes (send SQL to fill certain columns in table)
3. add line/edge (send SQL to create new row in association table)
4. edit line/edge attributes (send SQL to fill comment/label field)

Just to be clear, I am primarily interested in rendering & editing
instances, not schema (not ontologies, etc). Currently I have about 2000
nodes (which hold a lot of text values) and several hundred edges.

Any comments and/or suggestions are welcome.

thank you in advance,
