    Data Modeler

    Data Modeler

    A tool for creating data models and databases for Microsoft SQL Server

    Welcome to the page for "Data Modeler"; a free tool to create Microsoft SQL Server databases. If you use Microsoft SQL Server and are in search of a clean and intuitive (and free!) data modeler, search no further. With object-level DDL previews, schema support, real-time model validation and DDL regeneration, sub-models, bulk undo/redo, drag 'n' drop foreign key creation, a data dictionary, update/delete foreign key automation, and customizable fonts and colors, this data modeler is an indispensable tool in any DBAs toolbox. I've used a lot of data modelers, from open-source free software to expensive modelers like Embarcadero ER/Studio. None of them come close for me in terms of ease-of-use and productivity gains. select * from DataModelers where Indispensable='true'; (1 row(s) affected) Facebook https://www.facebook.com/DataModelerTool/

    OverCASE

    OverCASE

    A cross-platform integrated CASE system

    An integrated CASE system that: • Supports multiple views and stages of project development – from keeping track of reference documentation to analysis/design modelling, to project implementation, roll-out and tracking the project-related issues. • Supports distributed development of projects by multiple participants, while proactively enforcing access control rules and auditing changes. • Is available on all platforms where development takes place (Windows, Unix/Linux, MacOS, Solaris, etc.) • Offers ideological and conceptual integrity across all facilities. By adapting a new approach to CASE tool architecture (integration at repository level and developing a component-based CASE system instead of a monolithic tool) an entirely new species of tools can be brought into a useful existence – an integrated environment where all project-related activities can be performed efficiently.

    MBSE for MagicDraw

    Plugin for MagicDraw to support MBSE with SysML

    Support for more productive Model Based Systems Engineering, following the recommendations in the Cookbook of the INCOSE SE2 Challenge team http://mbse.gfse.de The Plugin for the MagicDraw modelling tool provides support for model based document generation which ties together system model and documents to keep them up to date and consistent, using a AWYSIWYG editor in MagicDraw. It provides basic support to model variants and extract variants from a system model. It provides support to generate organizational structures according to the SE2 Cookbook recommendations. It provides basic pattern based support to reason on a system model, for example to extract numbers like total power, cost, power consumption for a given product tree The MBSE plugin for MagicDraw requires MagicDraw 17.0 SP4 or higher with an installed SysML plugin 17.0 SP5 or higher. Installation instructions can be found in the file ReadMe.txt in the download area as well as the corresponding UMs.

    Unified Code Generation

    Unified Code Generation

    Open-source code generator for Simulink/Stateflow

    This project provides an open-source framework for the generation of high quality source code which is suitable for safety-critical applications and certification (e.g DO-178B). Currently a Simulink and Stateflow front-end and a C-language back-end are included. Some of the strengths of UCGN: - Clearly readable source-code - Separation of functionality and parameters ("tunable parameters") - Robust data storage (compile-time static structures in favor of pointer run-time constructs) - Clear software architecture, direct correspondence to the model architecture - Separation of reusable library code - Simplicity and uniformity of software interfaces (for testing etc.) The following features are supported by the Simulink/UCGN - Discrete single-rate Simulink models and libraries - Block library with 50+ standard Simulink blocks - Periodic, condition-driven Stateflow charts (including flowgraphs, loops) - Structured data types through bus objects - Simulink native enumer
