SceneDraw is an investigative tool, for police and private investigators that need to survey and diagram scenes for criminal and civil litigation. Scene Draw is not a CAD program nor is it a drawing program, it is a Data Driven Diagram software program for your reconstruction purposes.

It is the complete data measurement collection software tool for Microsoft Windows 98 to XP.

The program helps IT departments with change, incident, purchase, asset and dependency management by integrating into existing availability monitoring (HP SIM and GFI NSM) and monitoring availability itself. Generates disk growth prognostics, close customer interaction through e-mail and a web frontend, knowledge base (that assists during incident management), and asset management (based on data collection of Active Directory, WSUS, and more.

DBVA for JDeveloper (DBVA-JD) is a database design plugin tightly integrated with JDeveloper. Developers can design application with Class Diagram and ERD, and generate database tables from the resulting diagrams. It can also generate the persistent Java objects (ORM) for accessing database (Oracle, MySQL, Microsoft SQL Server...). Furthermore, you can perform reverse engineering by reversing existing database(s) to Class Diagram and ERD.

DBVA for JBuilder (DBVA-JB) is a database design plugin tightly integrated with JBuilder. Developers can design application with Class Diagram and ERD, and generate database tables from the resulting diagrams. It can also generate the persistent Java objects (ORM) for accessing database (Oracle, MySQL, Microsoft SQL Server...). Furthermore, you can perform reverse engineering by reversing existing database(s) to Class Diagram and ERD.

DBVA for Eclipse (DBVA-EC) is a database design plugin tightly integrated with Eclipse. Developers can design application with Class Diagram and ERD, and generate database tables from the resulting diagrams. It can also generate the persistent Java objects (ORM) for accessing database (Oracle, MySQL, Microsoft SQL Server...). Furthermore, you can perform reverse engineering by reversing existing database(s) to Class Diagram and ERD.

EventStudio is a CASE tool for Sequence Diagram, Call Flow, Message Sequence Chart, Use Case and Process Workflows generation. EventStudio goes beyond UML and supports advanced constructs that make it suitable for Real-time Embedded System Design, Protocol Design, Object Oriented Design, Telecom and Systems Engineering. With EventStudio, you enter your model in plain text and automatically generate diagrams in PDF and MS Word (EMF).
