GraphTalk and the metalogy

2005-06-01T02:26:00.000-07:00

GraphTalk was designed several years ago to do easy the CASE tool building.However GraphTalk is more generally a modeling environment.To illustrate GraphTalk, I choose a short example on metalogy (i.e. something about meta).Hypergraph:The main concept in GraphTalk is the concept of hypergraph:A hypergraph H can be defined as a pair (V, E), where V is a set of vertices, and E is a set of

Let talk about a new Eclipse Project, the MDDi (Model Driven Development Integration) project.MDDi project is dedicated to the realization of a platform offering integration facilities needed for applying a Model Driven Development (MDD) approach.This project will produce an extensible framework and tools, designed to support various modeling languages (UML (Unified Modeling Language)

MOF or EMF, GMF and GEF

For the time being, a very, very interesting proposition exists from the Eclipse consortium around the metamodeling framework.This project is the GMF (Graphical Modeling Framework) project from Eclipse. It is a very ambitious project and this GMF project can change totally the modeling tools business.The foundations are EMF for the meta-modeling (a kind of MOF) and GEF (2-D drawing graphical

I'm a new blogger (6 days; quite a baby still in this domain), so it will take time to find the good style.I'm a self-made blogger but, I understood several evident rules: To stay polite Don’t use text or picture from other materials. For text or document, we can use hyperlink references, for sources we want consider as an outside

Xerox software environments used by the GraphTalk team

Sorry to disappoint you, GraphTalk was not developed at Xerox PARC, even we had several meetings at Xerox PARC (mainly for some demonstration) and other meetings and demo too in other Xerox sites (Rochester Xerox Labs, etc...).GraphTalk was an internal project in the french operating company Rank Xerox France.We had the great luck to meet intelligent managers with openness to accept that a local

Niam tools

Niam (Nijssen Information Analysis Method) is the modeling method designed by G.M. Nijssen in Control Data Corporation in the 80th years.Several tools supported this modeling approach, at two different layers: Design and development stepsProduction steps Let start by the Production layer (because only few items): DBMS supporting the 5th NF formalism of Niam logical model (a

Even the title "My meta done" of my weblog seems a joke, the materials I wish to discuss are always serious, but not academic.I've however several real life stories which can show the difference between the plan and the reality.The bone stuck in my throatIn the year 1989, I was invited by the AFIM (Association française des ingénieurs et responsables de maintenance) Organization to give a

Maia and Niam

For this second blog, it's a new subject and a blog dedicated to Maia, or MAIA (Méthode d'AIde à l'Analyse). Maia is a modeling method designed and developed (with several CASE Tools) at the BNP Paribas, during the 1983-1986 period. In these 80's year, it was a great battle between several modeling techniques in France, Europe and in North America. Relational DBMS started to be used

GraphTalk

2005-05-15T03:25:00.000-07:00

This weekend is a particular weekend because I am deciding to write a blog about GraphTalk and more generally speaking about the GraphTalk project. But in few words, what is GraphTalk ? GraphTalk is a meta-case technology developed at Xerox during the 1986-1988 periods. Mounir Khlat and Patrick Jeulin are the two co-authors of this environment, even if a lot of developers were involved
