This book explores thedevelopment of distributed applications using the Common Object Request Broker Architecture(CORBA). In two weeks, it introduces you to the fundamental concepts of CORBA, walksyou through the development of a simple CORBA application, and then starts you developinga more complex application. You'll learn about CORBA's Interface Definition Language(IDL) and how to use it to describe interfaces between application components. You'llalso be introduced to the Object Management Group, the organization responsible fordeveloping the Object Management Architecture, a specification in which CORBA playsone part. Additionally, you'll learn about the CORBA architecture and related componentsof the Object Management Architecture--such as CORBAservices and CORBAfacilities--andsee how these building blocks are used to develop distributed enterprise applications.You'll gain familiarity with writing CORBA applications in both C++ and Java, thetwo preeminent languages for CORBA development.</P><P>In addition to the 14 Lessons, two Appendixes introduce you to many of the CORBAdevelopment tools available, and give you an overview of what the future holds forCORBA. Although CORBA can sometimes move at the speed of a standard defined by acommittee (not surprising, given the process used by the OMG to adopt new standards),CORBA continues to make strides that ensure its place at the forefront of distributedapplication development.<H2><A NAME="Heading1"></A><FONT COLOR="#000077">Assumptions</FONT></H2><P>You'll get the most out of this book if you have the following:<UL> <LI>Some knowledge of C++ or Java, although experience with any programming language will help you to understand the concepts presented in this book.<BR> <BR> <LI>Familiarity with the development tools, such as Visual C++, Java Development Kit (JDK), or other development environments, on your platform(s) of choice.<BR> <BR> <LI>Understanding of object-oriented analysis and design concepts. Such knowledge isn't absolutely necessary because this book introduces you to these concepts, but because CORBA is an object-oriented architecture, you'll benefit most from reading this if you're already familiar with object-oriented analysis and design.</UL><P>The best way to learn any new subject is to practice and experiment. To followthe examples presented in each chapter, as well as each quiz and exercise, you needaccess to the following:<UL> <LI>A computer of some kind. Because CORBA is cross-platform, almost any kind of computer will do--from a Macintosh, to a PC running Windows, to a UNIX workstation. Any machine supported by a CORBA development product (see the next bullet point) will do.<BR> <BR> <LI>A CORBA development product for your machine. Two of the more popular products include IONA Technologies' Orbix and Visigenic Software's VisiBroker. Many vendors offer an evaluation period for their products that provides more than enough time to complete this book. The C++ examples were developed using VisiBroker for C++; the Java examples use Sun's Java IDL package. However, the examples work with other products, with few or no changes.<BR> <BR> <LI>The appropriate compiler and/or other software development tools necessary to support your chosen CORBA development product. For instance, VisiBroker for C++ on Windows 95 or Windows NT requires Visual C++ 4.2 or higher (although compilers from other vendors work as well). For Java-based CORBA products, usually you only need a recent version of the Java Development Kit (JDK).<FONT COLOR="#000077"></FONT></UL><P><CENTER><P><HR><A HREF="../ch01/ch01.htm"><IMG SRC="../button/next.gif" WIDTH="128" HEIGHT="28"ALIGN="BOTTOM" ALT="Next chapter" BORDER="0"></A><A HREF="../index.htm"><IMG SRC="../button/contents.gif"WIDTH="128" HEIGHT="28" ALIGN="BOTTOM" ALT="Contents" BORDER="0"></A> <BR><BR><BR><IMG SRC="../button/corp.gif" WIDTH="284" HEIGHT="45" ALIGN="BOTTOM" ALT="Macmillan Computer Publishing USA"BORDER="0"></P><P>© <A HREF="../copy.htm">Copyright</A>, Macmillan Computer Publishing.
