Visible Systems enhances support for UML 2.1 standard for modeling tool

New modeling tool capabilities support software project teams for both software and hardware engineering initiatives

FRAMINGHAM, MASSACHUSETTS - September 8, 2009 Visible Systems announces a new edition of its award winning modeling tool Visible Analyst.  Completing a new development initiative, new modeling capabilities have been added to support state of the art UML 2.1 modeling standards.  The purpose of the Unified Modeling Language (UML) is to provide comprehensive notation for communicating the requirements, architecture, implementation, and deployment phases of a system.
Visible Analyst 2009 is an easy to learn and use modeling tool for systems analysis and design, database design, and UML modeling of team-based systems.  The last release of Visible Analyst added support for OMG's Business Processes Modeling Notation (BPM) geared toward business analysts and developers.
Two key diagram types are included in the new release are Component diagrams and the Deployment diagrams. Component diagrams focus on the software components of a system and Deployment diagrams support the hardware components of a system.
The main purpose of the Component diagram is to visually show the structural relationships between the components in a system.   A component is an autonomous, encapsulated element within a system that provides for one or more interfaces. Typically components are larger design elements that will be implemented using replaceable modules.
Deployment diagrams model the physical architecture of a system showing the relationships between the software and hardware components in a system, as well as the physical distribution of the processing.  Deployment diagrams depict the static view of the run-time configuration of processing nodes and the components that run on those nodes.  The deployment diagrams show the hardware for your system, the software that is installed on that hardware, and the middleware used to connect the disparate machines to one another.
Deployment diagrams are related to component diagrams because they are used to deploy the components from Component diagrams. Deployment diagrams are important because they control the performance, scalability, maintainability, and portability of a system and are used during the implementation phase of development.

Deployment diagrams are differentiated from component diagrams in that they show where "components and artifacts" are used in relation to a deployed system.  The deployment diagram includes the notational elements used in component diagrams with a couple of additional concepts including a node. A Node represents physical machine or virtual machine node. 
The communities who will benefit most from the new component and deployment diagrams include: enterprise architects, system administrators, developers, system engineers, and other key stakeholders on a project development team.
Architects: Component diagrams offer a very intuitive format for architects to model their solutions.  The component diagram allows the architect a visual tool that ensures that a system's necessary functionality is properly implemented by its components.  This verification process ensures that the implemented system will be acceptable its users.
Developers: A component diagram can be very useful to developers because it gives them a high level view of the system that they will build.  This blueprint helps developers to formalize their roadmap for implementation decisions such as tasks, assignments and skills enhancements.
System Administrators: Component diagrams are useful to system administrators because they can see at an early stage the logical software components that will run their systems.  Component diagrams will provide early information about components and relationships that will help them to plan ahead. 
Stakeholder Communication: Component diagrams are intuitive and are generally used by the implementation staff, as well as other stakeholders by giving them a basic understanding of the system being built.
Systems Engineers: Systems engineers will use deployment diagrams to visualize the hardware topology of their systems.
System Production Staffs: System Production Staffs: Production staffs will heavily use deployment diagrams to model the physical run time of their systems.

HARDWARE REQUIREMENTS: All editions of Visible Analyst are available as 32-bit Windows applications for Windows NT 4.0, 2000, 2003, XP, Vista or Windows 7. A Pentium class processor is required with a minimum of 128MB RAM, 20MB of free disk space for the installation and 100 MB of free space for the projects, and a compatible pointing device.

Visible Analyst 2009 is currently available.
