The papers:

Tibbets, "Enterprise Architectures: A Comparison of Vendor Initiatives"

Charles R. Morris and Charles H. Ferguson. How Architecture Wins Technology Wars.

The Text

Ch 2.5, Ch 4.3.4

Hints:

It is not so important to understand the details of the different vendors' products, but rather focus on the underlying stylistic differences between their architectural frameworks. Also think about the overall architectural evolution of the industry. [Mor93] examines the structure of the industry.

As professionals you'll probably be interested in the whole paper, but for purposes of this course, focus on the discussions of standards and open systems. Once again we are revisiting layered architectures, Compare the diagrams in the text with the diagrams in Tibbets.

Questions:

1. What is the primary difference between IBM's and Microsoft's approach to enterprise integration?

2. What is the main distinction between "architecture" and "marketecture?"

3. Briefly compare the advantages and disadvantages of open vs proprietary systems.
