Course Description

When designing a significant software system, several design decisions about the structural, architectural, and behavioral properties of the system are made and documented.
In this course, techniques and notations are introduced for specifying these properties of software systems. Software systems are studied at various levels of abstraction from architectures to subsystem decompositions to module and class interfaces and dependencies.

In this course, students will learn to analyze, express, and implement software designs. The course will focus on service-oriented architecture. Service-oriented computing provides a solid foundation for creating modern applications by applying the lessons learned from object orientation, component software, message oriented middleware and distributed computing.

The course will not use a textbook - lectures will be formulated from material developed in academia and industry on Software Architecture and SOA.

 

Intended Audience

This course is intended for graduate students in Software Engineering and Computer Science. Graduate students in other programs may take this course with the permission of the instructor, as significant programming experience is a pre-requisite.

Before taking this course, students should be proficient in either the Java or a Microsoft .Net language such as C#. Students familiar with other object-oriented programming languages such as C++ may take this course but they will have to learn Java or C# if they want to simplify their lives when it comes to creating the project deliverables. I will accept projects developed in C++, but this will require significantly more work than using Java or C#. Students lacking a background might want to consider taking this class at another time unless they are committed to spending a lot of time learning Java or C#. For your reference here are some good reference materials:

Class Meeting Times & TA Information

CS575 will meet from 6:00 - 8:40PM on Monday evenings in University Crossings 153. Office hours are by appointment or immediately before class. 

Class Format for CS575  <to navigation bar>

The format of this course will be similar to that of a Computer Science conference. Each week we will review between 1 and 3 papers following the lecture outline. As the instructor I will present a 20 minute overview of the selected paper(s) and then we will have a 20-25 minute conversation about each paper. Engaging discussion of the lecture materials is a critical aspect of this class. Class participation will be factored into consideration for students whose grades fall on a borderline.

A word of caution: For most students, this course will require a fair amount of dedicated time. Reading 2-3 research papers per week (20-30) pages is not like reading a novel, and will require some degree of time commitment to gain the proper level of understanding. Feel free to contact me if you have any upfront concerns about your ability to succeed in this course.

Lectures  <to navigation bar>

This course will most likely be different from other courses that you have taken at Drexel. We will not be using a textbook since there are no good textbooks available on service-oriented architecture at this time. To gain the most out of this course you need to read the required material in advance of class and come to the lectures prepared to discuss the material.

Lecture notes will be provided in Adobe Acrobat and Microsoft PowerPoint format - Click on the appropriate icon to download a copy of the notes. The lecture notes are copyrighted material – please email the author for permission to reuse.

    Due: Position Paper Extended Abstracts

  1. We will start this week by covering an overview of the Sofware Architecture lecture materials that we did not get to cover from Week 2.
  2. Paper Presentation and Discussion
    "A Reference Architecture for Web Servers" by A.E. Hassen Here are the lecture notes ->
  3. We will be looking at some newer reference architectures for SOA. The The OASIS SOA Reference Model, The IBM SOA Reference Architecture, The SOA Alliance Reference Architecture [longer forrmatted HTML version] . Note we will probably not get to them all. Lecture Notes->
  4. Also, review A Reference Architecture For SOA, lecture notes by Brian Mitchell , It might be a good idea to scan the paper "Paradigm: Service Oriented Computing" by Nikolai Dokovski, Ing Widya, Aart van Halteren to prepare for this lecture. This paper is published online [HERE]. We will be covering this in week 5.
  5. I also wanted to give you a reference to the "SOA Blueprints" from the MiddlewareResearch organization, now published by the OASIS group. We will not be covering it in class, but may be referencing it.
