Version 14 of Metakit2

Updated 2002-03-13 17:14:13

MetaKit has its own Wiki [L1 ] and home page [L2 ]. MetaKit is the persistence engine for WiKit, of course.

Mark Roseman has written a tutorial [L3 ] on MetaKit for Tcl developers.

DGP For what it's worth, here are the points I found most useful in the Roseman intro:

• Use properties that define as small a unit of information as possible.
• Creating more views is a good thing. Do that, don't muck up a single view with special cases.
• Moving data to/from a Tcl array is easy and familiar to Tclers.
• Emphasis that restructuring of a view layout means you can continue revising your data model as you go. Just start coding; you can change it later.
• Some discussion when subviews are good vs. additional views.

"... many of the integrity checks required in traditional database use are not required in Metakit, because Metakit offers nested views -- a cleaner way to represent the relationships often enforced by integrity constraints."
