Component Object Model (COM) and Distributed Component Object Model (DCOM) provide the foundation for Microsoft's distributed object strategy. They are the glue that should enable Microsoft to bring their other core products and technologies such as ActiveX, Internet Information Server, and Internet Explorer to the enterprise. In other words, this is Microsoft's answer to CORBA, Netscape, and JavaBeans. This text discusses: how to use COM and DCOM with existing legacy systems; how COM and DCOM fit into two- and three-tier client/server architectures; "Thin" versus "Thick Clients" and how they relate to Microsoft's Active Server Platform; new technologies from Microsoft such as Viper and Falcon; and security issues for distributed objects.
An expert′s unbiased appraisal of Microsoft′s object technologies and how they can work for your enterprise
In COM and DCOM, internationally recognized object–technology expert Roger Sessions offers a lucid, unbiased appraisal of Microsoft′s distributed objects strategy. Focusing on issues of crucial concern to both developers and managers, Sessions considers all of Microsoft′s object technologies and explains the huge impact they are likely to have on the future of enterprise computing. Microsoft has targeted the mainframe market and this book explains exactly how they plan on doing it. Topics include:
- How Visual Basic, Java, COM and DCOM work together
- Creating highly efficient object pools
- Using the Microsoft Transaction Server, SQL Server, and the Microsoft Message Queue Server (Falcon) to develop unbelievably robust, multi–tier applications without mainframes
- Integrating legacy database systems into your system design
- Using Wolfpack to create highly available clusters of workstations that outperform mainframes at a fraction of their cost
- Security issues for components
- 10 Rules for distributed component programming
- Extensive program examples include complete Java, Visual Basic, IDL and batch files, and can be downloaded from our Web site at www.wiley.com/compbooks/
