Microsoft’s New Database Modeling Tool: Part 7
by Dr. Terry Halpin

This is the seventh in a series of articles introducing the database modeling solution in Microsoft Visio for Enterprise Architects, which is included in the Enterprise Architect edition of Visual Studio. NET. This article discusses how to add index constraints to an ORM model, show/hide constraints via layers, specify data types, and control column name generation in the resulting relational model. Familiarity with ORM and relational database modeling is assumed. For an overview of ORM, see [1]. For a thorough treatment of ORM and database modeling, see [2]. For previous articles in this series, see [3], [4], [5], [6], [7] and [8].

A 3D Software Architecture Framework
by George Jucan

The endeavors most commonly seen today in the IT world have a wide coverage are, usually departmental or enterprise wide. Either a Data Warehousing effort or the consolidation of many disparate applications into an integrated system, such a project is usually characterized by a long duration and a large number of resources utilized.

Discrete Modeling and Simulation in TOOMS:
A Combined Event/Process Approach
by Nasreddine Hallam

Turbo Object-Oriented Modeling and Simulation (TOOMS) is an object-oriented general-purpose simulator for combined systems that allows multi-systems modeling and therefore, multi-models simulation. The modeler is given the ability to perform modular modeling or concurrent modeling. Indeed, s(he) can model a complex system into many sub-models, or in one-shot, models many systems into many concurrent models. This is the main characteristic of TOOMS. This work is to unfold the technical design of the discrete part of TOOMS.
