Free modeling tool software for linux

FireAnt is an Eclipse plugin for modeling complex remote deployment and configuration processes for EJBs.

It allows developers to model the deployment and execution of groups of packages and configuration scripts on remote targets.

After modeling a deployment plan, FireAnts runtime infrastructure SSHs into each target, copies over the specified files, deploys the EJBs and Webapps, runs any required deployment scripts, and then cleans the staging environment.

K-3D is the free-as-in-freedom 3D modeling, animation, and rendering system for GNU / Linux, Posix, and Win32 operating systems. K-3D features a robust, object-oriented plugin architecture, designed to scale to the needs of professional artists, and is designed from-the-ground-up to generate motion-picture-quality animation using RenderMan-compliant render engines. We strongly recommend the Aqsis render engine for use with K-3D.
K-3Ds innovative interactive tutorial system will introduce you to basic use of the program. New tutorials can easily be recorded and shared with the rest of the community.
K-3D allows you to create and edit documents in multiple realtime OpenGL solid, shaded, texture-mapped views. You can even model, animate, and interact with animations while they play back for maximum productivity!

The Generic Eclipse Modeling System (GEMS) is a MDD tool for Eclipse that allows for the rapid development of Draw2D plugins.
Developers specify the rules for a domain language using a metamodel and the tool generates a diagram editor plugin that enforces the rules from the metamodel.
Interpreters can then be written to traverse the model and generate code, perform analyses, or execute the model.
Whats New in 2.0.5_01 Stable Release:
- This release contains fixes to minor bugs present in 2.0.5.

PyDBDesigner is a free relational database modeling tool that is planned to be able to design both logical and physical models similarly to Erwin(c) and PowerDesigner.

Its goal is to provide a useful toolset that allows developers analysts and database designers to design and develop databases from the verbal model to the schemas and SQL scripts.

There is no such a tool is available as a freeware. There is a project called DbDesigner, but it seems to be discontinued and its functionality is not enough for modeling (and the concept behind it seems to be weak).

The concept is to implement ER logical and physical modeling paradigm as correctly as possible, meanwhile creating a tool that is useful as soon as it is possible. So the development concept is that features are added rapidly, but carefully (trying to leave space to the features that come later).

For example, the "type" class is good enough to implement data domains, however, the code that actually creates domains using GUI is not implemented. The "type" attribute of the properties uses this object, so adding domains to attribute types is easy.

MFbyAS is an Italian Web-based financial monitoring system.

Xholon runtime framework executes applications that are event-driven or that have highly dynamic structure or behavior. Specify your models using XML and Java, or using third-party UML2 tools and MDA transformations.
To get started, read or actively work through the basic HelloWorld tutorial. Its a very simple application, but it demonstrates many of the main concepts.
For more detail on the concepts behind Xholon, you might want to read one of the papers thats been published. These describe how to model cells and other complex biological entities using tools designed for developing real-time and embedded systems.
This earlier work used Rational Rose RealTime and C++, rather than the current Java. Xholon is intended to be a runtime framework that can execute the same types of systems described in those papers, plus many more traditional non-biological event-driven systems.
The goal of the Cellontro sister project is to develop complex biological simulations using the Xholon framework. Most of the features described in the published papers have been re-implemented as Cellontro applications using Xholon.
Also have a look at the sample applications that are included with the Xholon software. These give an idea of the range of applications that can be supported by the Xholon runtime framework.
These have been employed as use cases to determine what functionality is most important in Xholon. The digital watch simulation is a good example of a Xholon application with a hierarchical state machine, developed using a UML modeling tool.
A Xholon is essentially a holon. A holon is an entity that lives within a hierarchical structure, and is both a whole and a part at the same time.
In mainstream computer science terms, a Xholon is a node in a tree. The node has a single parent, possibly one or more children, and possibly one or more siblings. A Xholon may also be an active agent able to interact in real-time with other Xholons in the tree.
In UML2 terminology, a Xholon is a structured classifier that may exist as a part within other structured classifiers, and that may in turn contain other structured classifiers as parts of itself. The result is a hierarchical containment structure, nested to an arbitrary number of levels.
As a part, a Xholon plays a specific role within another structured classifier. Xholons are UML classes that are subsequently refined using UML2 composite structure diagrams. Structured classifiers interact with each other through ports, by passing messages or by making function calls.
Using the more philosophical terminology used to describe holons, a Xholon is something that is simultaneously both a whole and a part. Since everything in the universe is a holon, then everything running within a computer application should be a Xholon. The term holon was invented by Arthur Koestler in 1967.
The Xholon Project is inspired by biological concepts. A major incentive behind the project is to build a run-time environment that is equally adapted to running simulations of biological systems, and to running more traditional real-time, embedded and other event-driven reactive systems.
Xholon applications may contain structures that are highly mutable. A Xholon is an active agent that can modify the tree structure in which it lives. It can navigate the tree to interact with any other node, it can add, delete or modify other nodes, it can exchange messages with other nodes, and it can move itself to another position within the tree.
The Xholon Project incorporates many concepts of the Real-time Object-Oriented Modeling (ROOM) methodology, much of which has been incorporated into UML2. At the same time, Xholon removes some of the limitations of ROOM to allow for greater flexibility, mutability and mobility of active objects.
The Xholon run-time can serve as a target for a Model Driven Architecture (MDA) transformation pipeline. MDA stresses the importance of models, and the ability to transform those models, through a series of steps, into an executing target system.
You can create your model using a UML tool such as Gentlewares Poseidon or NoMagics MagicDraw, save the model as an XMI file, transform it using XSLT (or by some other MDA means) into a Xholon model and application, and then execute the model.
