An in-depth architectural overview of COM+ component technologies for enterprise developers, this book offers a detailed look by providing implementation details and sample code. Content includes scalability, queued components and MSMQ, the in-memory database, and role-based security.

Inside COM+ Base Services examines many aspects of Microsoft's Component Object Model+ in depth. The book provides a great deal of information well-suited to experienced C++ programmers, as well as thorough explanations and useful code examples.
As with most books from Microsoft Press, this volume comes with a well-organized CD-ROM that contains complete source code for the examples presented in the book. (Most of the examples are actually code fragments, but the CD-ROM contains the code in its entirety.) One very nice feature of the CD-ROM is that it includes the contents of the book in Microsoft Electronic Book format, which makes searching for passages and copying code fragments very easy. Not limited to the C++ audience only, the book presents COM+ implementations in Visual Basic and J++ too.
It should be mentioned that this book targets a lot of information at those who know C++ and have some background with the Windows API (and preferably some with OLE or COM.) For those with only a Visual Basic background or who want an overview, this book is probably too C++-specific. Also keep in mind that this book is an update of Inside Distributed COM. Several topics that are new to COM+, such as message queuing and transactions, are not covered in this book (the next book in the series, Inside COM+ Component Services, due out in spring 2000, might cover these topics).
Overall, if you are a C++ programmer, are using the Windows API, and are interested in learning about DCOM and COM+, this book provides clear explanations, useful programs and code fragments, and a lot of detailed examples. --John Keogh
