Overview / Catalog Description
This course focuses on ways of designing and integrating an information systems architecture. The course
explains the different forms of corporate information systems and their interaction. While in the past, large
computer systems were often self-contained, in current systems, it is more likely that such systems are part
of an overall architecture including many smaller hardware devices and operating systems. The student will
learn about the building blocks of current IS architectures, and then will learn how to connect them to solve
problems. In particular, the student will gain an understanding of principles of design, including the control
of memory hierarchies, ways of modularizing, ways of parallelizing tasks, ways of generating a new
architecture, and ways of evaluating the architecture.
Introduction to Course
While information systems students are trained in ideas relating to enterprise systems, they often are not
familiar with full extent of the technologies underlying an integrated information systems architecture.
This course grounds students in this underlying technology, and then teaches them how to connect
components to form an architecture that will answer the needs of institutions.
These architectures are important to those dedicated a career in information systems: the architectures must
be understood in order to function in an IS department. These architectures are important for managers as
well as analysts and programmers: managers are expected to understand a systems diagram of present
systems and speak to the fit of a proposed architecture for accomplishing institutional goals.
Thus, the course will make students proficient in the vocabulary and grammar of modern enterprise
systems, the techniques for integrating them, and this proficiency will be useful throughout the students’
careers.
Learning Goals

3.
By the end of this course, students will be able to formulate a series of plausible alternative
designs for integrating technologies.
Students will know the different components of IS architectures, how they work, and how they
integrate with each other.
Students will improve their ability to communicate about design in group and presentation
settings.

Suggestions for supplemental reading
There are three suggested texts, which complement each other. The first book is general, about design,
providing methods for designing systems and other things. The second book explains the ideas and
standards relating to enterprise architecture. The third book is more technical, discussing the kinds of
problems architects will face, and providing some potential solutions. The books do not address in detail
some of specific issues that drive the design of systems, and so I have assigned Wikipedia articles that
supplement the books and the lectures.
Brooks, F. P. The Design of Design: Essays from a computer scientist, Addison-Wesley 2010.
A book about the design of systems (and other things) from the author of the mythical man month
Lankhorst, M. Enterprise Architecture at Work: Modelling, Communication and Analysis, 2nd ed., 2009,
Springer (or the 1st edition, available in the library in electronic form for download.)
A high-level look at systems architecture
Garland, J., and Anthony, R. Large-Scale Software Architecture: A Practical Guide using UML, Wiley,
2003.
A software architecture book, using UML. More technical than the Lankhorst text.
Other Texts:
2
Maier, M.W. and Rechtin, E. The Art of Systems Architecting,2 nd Edition, CRC Press, 2000.
The book contains good heuristics for how to design systems, with a focus on military systems.
Fowler, M. Patterns of Enterprise Application Architecture, Addison Wesley, 2002.
This is a technical book, more so than Garland, with Java code associated with the different patterns.
Erl, T. SOA Design Patterns, Prentice Hall, 2009.
This book focuses specifically on Service Oriented Architecture.
Baldwin, C. Y. and K. B. Clark (2000). Design rules. Cambridge, Mass., MIT Press.
This book is about modularity.
Shaw, M. and D. Garlan (1996). Software architecture: perspectives on an emerging discipline. Upper
Saddle River, N.J., Prentice Hall.
A good academic book on software.
Assignments
Students will master the conceptual material through the lectures and the associated readings. They will be
quizzed weekly. Towards the end of the course, they will engage in a large-scale group design project, to be
presented by the last class of the semester.
I encourage you to build on the ideas of others, and I require you to cite the work that influences your
design. Please follow this link and read carefully: http://www.plagiarism.org/.

Ethical Conduct
The following statement is printed in the Stevens Graduate Catalog and applies to all students taking
Stevens courses, on and off campus.
“Cheating during in-class tests or take-home examinations or homework is, of course, illegal and immoral.
A Graduate Academic Evaluation Board exists to investigate academic improprieties, conduct hearings,
and determine any necessary actions. The term ‘academic impropriety’ is meant to include, but is not
limited to, cheating on homework, during in-class or take home examinations and plagiarism.“
Consequences of academic impropriety are severe, ranging from receiving an “F” in a course, to a warning
3
from the Dean of the Graduate School, which becomes a part of the permanent student record, to expulsion.

The Graduate Student Handbook, Academic Year 2003-2004 Stevens
Institute of Technology, page 10.
Consistent with the above statements, all homework exercises, tests and exams that are designated as
individual assignments MUST contain the following signed statement before they can be accepted for
grading. ____________________________________________________________________
I pledge on my honor that I have not given or received any unauthorized assistance on this
assignment/examination. I further pledge that I have not copied any material from a book, article, the
Internet or any other source except where I have expressly cited the source.

Please note that assignments in this class may be submitted to www.turnitin.com, a web-based antiplagiarism system, for an evaluation of their originality.
Course/Teacher Evaluation
Continuous improvement can only occur with feedback based on comprehensive and appropriate surveys. Your
feedback is an important contributor to decisions to modify course content/pedagogy which is why we strive for
100% class participation in the survey.
All course teacher evaluations are conducted on-line. You will receive an e-mail one week prior to the end of the
course informing you that the survey site (https://www.stevens.edu/assess) is open along with instructions for
accessing the site. Login using your Campus (email) username and password. This is the same username and
password you use for access to Moodle. Simply click on the course that you wish to evaluate and enter the
information. All responses are strictly anonymous. We especially encourage you to clarify your position on any of
the questions and give explicit feedbacks on your overall evaluations in the section at the end of the formal survey
which allows for written comments. We ask that you submit your survey prior to end of the examination period.
