NetBeans - First Open Source Tools Platform to Implement Model Driven Architecture (MDA)

MDA to Simplify Implementation of Web Services by Separating Architecture From

Deployment Infrastructure



May 07, 2002, 01:00 ET from Sun Microsystems, Inc.

    SANTA CLARA, Calif., May 7 /PRNewswire-FirstCall/ --
 Sun Microsystems, Inc. (Nasdaq:   SUNW) today announced that the company has
 contributed a series of modules supporting Object Management Group's (OMG's)
 Model Driven Architecture to the NetBeans(TM) open source project
 (www.netbeans.org). This makes the NetBeans platform the first of its kind to
 support the Model Driven Architecture.
     The Model Driven Architecture (MDA) helps protect organizations' software
 investments by capturing business logic -- business processes and their
 appropriate interactions -- in re-usable models. The MDA can help
 significantly simplify the implementation of Web services, as the architecture
 insulates models from changes in the deployment infrastructure for the
 services.
     The MDA represents an advanced approach to software design based on models
 created using languages such as the Unified Modeling Language (UML). As
 business requirements change or evolve, components of model-driven
 applications can easily be replaced, as long as they are standards based.
 Models use a set of metadata -- the data describing the structure and
 characteristics of program elements or data. For example, customer data might
 include a first name, last name, address, and phone and customer numbers.
 Metadata describing customer data would specify whether these elements are
 alphanumeric or numeric, the maximum length and format of the phone and
 customer numbers, and so forth.
     Sun has recently contributed Metadata Repository (MDR) modules to
 NetBeans, to make it easier for developers to support another programming
 language without extensive extra programming and to write NetBeans-based tools
 that interoperate with standards-based modeling tools. These new modules
 underline NetBeans commitment to a totally standards-based,
 language-independent approach to software design. The Sun ONE Studio developer
 products (formerly Forte tools) are based on the NetBeans platform.
     "Sophisticated organizations see the benefits of a model-driven approach,
 which is the future of effective software design," said Peter Young, vice
 president, Sun ONE Studio Tools, Sun Microsystems. "Rather than creating
 single-purpose programs and laboriously wiring them together to interact as
 needed, organizations are defining their business operations as a series of
 interdependent processes. The NetBeans community is pioneering model-driven
 development by providing tools for other developers, and as the architectural
 foundation for the platform itself."
     "As a longtime supporter and active participant within the OMG, it is a
 delight to count Sun among a growing list of dedicated companies who have
 acknowledged Model Driven Architecture as a solid solution to enterprise
 integration issues -- a solution that promises to outlast other quick fixes by
 at least twenty years. By implementing MDA, NetBeans will help ensures that
 the development of mission-critical information systems are rooted in
 standards that have the ability to adapt to new hardware capabilities and new
 software platforms as they become available," said OMG Chairman and CEO,
 Richard Soley.
 
     The NetBeans Metadata Repository
     The NetBeans Metadata Repository provides support for modules that need to
 create, store and retrieve metadata. With its extensive support for the
 relevant standards, NetBeans will ultimately make it easier for developers to
 build model-driven programs. In addition, developers can support new
 programming languages without tediously writing APIs and custom support
 classes for each language.
     The MDR implements OMG's Meta Object Facility (MOF) -- an abstract
 language for describing metamodels -- and integrates it into the NetBeans IDE.
 The MOF implementation uses the Java(TM) Metadata Interface, a standard for
 expressing metadata in the Java language that is currently in review by the
 Java Community Process as JSR-40. The MDR adds features such as event
 notification to help integrate it with the IDE. The MDR also supports XML
 Metadata Interchange (XMI), another OMG specification that has already been
 implemented by several leading vendors.
     The MDR includes an engine library, the module integrating it with the
 NetBeans IDE, a development toolkit and tools for viewing and interacting with
 metadata. These tools represent the foundation for robust language-neutral
 refactoring support in the NetBeans IDE. The MDR can be used as a stand-alone
 library independent of the NetBeans IDE by third parties, such as modeling
 tools vendors that need a standards-compliant metadata repository.
 
     Benefits of the NetBeans Metadata Repository
     The MDR offers a number of benefits to developers and vendors:
     -- It provides support for developers who implement modules that generate
        or use metadata. This makes it easier for developers to create tools or
        modules that interoperate with other tools that support these
        standards. For example, most leading UML tools already support XMI.
     -- Given a language model, the MDR will generate all the interfaces
        representing an API for support of that language within the IDE. The
        MDR provides a language-neutral standard, and saves developers the
        effort of writing their own APIs for each language.
     -- Some operations within the IDE will be faster when implemented using
        metadata. The MOF standard can be used to integrate various types of
        tools for modeling, code generation, code analyses, dependency
        management and so forth.
     -- Based on the MOF standard, developers can write generic,
        language-neutral tools for working with metadata, such as class
        browsers and search tools.
     -- Objects can interpret events issued by the MDR, such as class creation,
        class or method renaming or signature changes. For example, when an
        event is detected, modules can apply code changes or offer to refactor
        the affected code.
