- Haven't had much luck looking around on my own, so I thought I'd
- ask the net for a little help...
-
- I'm looking for some kind of a package to do generalized
- dependency management. It doesn't have to be real fancy, but I think the
- following would be the major components of the package:
-
- - Able to enter simple dependencies: X is affected by Y, X affects Y.
-
- - Some kind of simple presentation method for displaying cascading
- dependencies (X affects Y, Y affects Z; somehow, we should be able
- to be told that X affects Z without having to explicitly enter
- that dependency into the system). This means only the simple
- dependencies have to be initially understood by us slow humans...
-
- - Ability to detect cycles in the dependency graph, which are possibly
- indications that something has been entered incorrectly (yes, I know,
- not always, but the ability to recognize cycles is still useful).
-
- - Simple searching capabilities.
-
- - Possibly some small number of hardcopy-producing options.
-
- It would also be nice to be able to specify different types
- of dependencies between parameters, instead of all dependencies being
- assumed to be the same. But, this complicates things in a couple of
- different ways, and is not necessary in my initial application.
-
- Once you start having to manage more than about 20 parameters
- in the dependency graph, doing this by hand is prohibitive. Using a
- drawing tool of some type usually falls apart at about this number of
- parameters as well. A simple matrix can handle a few more, maybe 40
- parameters, but doesn't make the cascading dependencies obvious.
-
- My initial application will involve 200 to 250 parameters, at
- current estimates.
-
- Please e-mail responses to me, I'll summarize to the net. Thanks!!
