Many companies in the modern-day business environment are experiencing a significant increase in the strategic value of their software. For this reason, stakeholders in the software development industry are looking for ways to automate and streamline the software development process. Their aim is to improve the quality of software products and reduce costs. Software developers and engineers also want to find solutions to architectural glitches, security issues, replication, and other problems. Some of the architectural problems in software products have emerged because of the need to develop simple software for the internet and new technologies. The best solution is to use the appropriate technologies, frameworks, and programming tools. The Unified Modeling Language (UML) is one of the best tools designed to address the aforementioned problems. It is important for companies to capitalize on UML tools because today’s business world is highly competitive.

Unified Modeling Language (UML) is a modeling language which is intended to provide a standard way to visualize the design of a system. The Unified Modeling Language offers a way to visualize a system's architectural blueprints in a diagram including elements such as activities, jobs, individual components of the system, how they can interact with other software components, how the system will run and how entities interact with others. UML has many types of diagrams, which are divided into two categories as structural information and that represent general types of behavior. Structure diagrams emphasize the things that must be present in the system being modeled. Behavior diagrams emphasize what must happen in the system being modeled. Interaction diagrams, a subset of behavior diagrams, emphasize the flow of control and data among the things in the system being modeled.

Open Source and Free Unified Modeling Language (UML) Tools : ArgoUML, StarUML, BOUML, EclipseUML, Dia, GenMyModel, UML Modeller, Papyrus, NClass, UMLet, NetBeans IDE, Plantuml, Open ModelSphere, gModeler, RISE, Violet, Oracle Jdeveloper, Oracle SQL Developer are the Top Open Source and Free Unified Modeling Language (UML) Tools.

What is Unified Modeling Language (UML) Software

The Unified Modeling Language (UML) Software provides a general-purpose, developmental, modeling language which is intended to provide a standard way to visualize the design of a system. UML offers a way to visualize a system's architectural blueprints in a diagram including elements such as any activities, individual components of the system, and how they can interact with other software components, how the system will run, how entities interact with others (components and interfaces) and external user interface. UML diagrams represent two different views of a system model, Static (or structural) view and Dynamic (or behavioral) view. Static (or structural) view emphasizes the static structure of the system using objects, attributes, operations and relationship and includes class diagrams and composite structure diagrams. Dynamic (or behavioral) view emphasizes the dynamic behavior of the system by showing collaborations among objects and changes to the internal states of objects. This view includes sequence diagrams, activity diagrams and state machine diagrams. UML models can be exchanged among UML tools by using the XML Metadata Interchange (XMI) format.

UML is a general-purpose, object-oriented modeling language that allows software developers to visualize a system before the actual development process. UML tools support the functions of UML. Software developers, engineers, and other stakeholders use them to visualize the architectural blueprint of a system in the form of a simplified diagram. The diagram represents the key elements of the system such as activities, interfaces, and various components. It also shows relationships between the different software components as well as how the finished product will operate. UML diagrams usually represent the model of a system in static (structural) or dynamic (behavioral) view. In the static view, diagrams include objects, relationships, activities, and attributes that represent the system. In the dynamic view, diagrams represent the behavioral aspects of the system. In simple terms, structural diagrams show the necessary elements while behavior diagrams represent what must take place in the system. With the right UML tools, companies can visualize the structure and design of their software systems.

What are the features of Unified Modeling Language (UML) Software

What are the features of Unified Modeling Language (UML) Software

  • UML Diagram Generation – Software developers, engineers, business users, and other users use UML tools to create and edit UML diagrams such as class, component, communication, sequence, activity, object, and profile diagrams. These tools usually use object-oriented techniques to describe and visualize the software production process.
  • Code Generation – UML tools can generate code from models and generate models from codes. The latter is commonly known as reverse engineering.
  • Document Generation and Reporting – UML tools allow users to generate impressive reports. Users can also export model diagrams in different formats and generate documents.
  • Scaling – Business users need to manage their complex systems as they increase in scale. The scaling feature allows users to scale a system to a multi-user scale depending on their changing needs.
  • Database Schema Generation – This feature allows software developers, engineers, and other users to develop database schemas from UML designs.
  • UML 2.x standard and supports UML diagrams such as Class, Object, Use Case, Component, Deployment, Composite Structure, Sequence, Communication, Statechart, Activity and Profile Diagram.
  • Features for Entity Relationship Diagrams.
  • Features for Data Flow Datagrams.
  • Generate source code from models and generate model from source codes.
  • Publication as HTML documents, and PDF documents.

Some of the benefits include :

Unified Modeling Language (UML) Tools Benefits

Unified Modeling Language (UML) Tools Benefits

  • UML tools use a general-purpose language which different stakeholders such as software coders, analysts, designers, testers, and customers can understand. For example, interested customers may not understand the code, but they can understand diagrams.
  • UML tools are scalable meaning users can scale them to meet their changing needs.
  • UML is flexible and most programmers use object-oriented programing languages.
  • UML tools can model almost all types of applications.
  • There’re many UML tools including proprietary and open-source software to suit the needs of every user.
