Introduction

COP3331: Object-Oriented Analysis and Design

Course Director: Ian Douglas

Instructor: David A. Gaitros, gaitrosd@cs.fsu.edu , (850) 644-4055







Welcome to Florida State University’s COP 3331: Object-Oriented Analysis and Design. This course assumes that you have taken COP 3330: Object-Oriented Programming and an introductory course in Computer Science. In particular, we assume that you have already been introduced to an object-oriented programming language and understand the concepts of encapsulation, inheritance, and polymorphism.

Developing a proficiency in programming is a basic skill requirement for both computer scientists and software engineers; however, programming skills alone are insufficient to make you a successful software engineer. For large-scale problems, an understanding of and experience in systems analysis and design are also required. In this course you will begin to develop such knowledge and skill, and increase your familiarity with the principles of software engineering. You will also gain practical skills in using Unified Modeling Language (UML).















Help with FSU Procedures and Technology






A complete learning community and support group will help answer your questions and remedy any problems, from enrolling in courses and developing an academic plan to accessing your course website and submitting assignments via the Web.





For Help with University or Course-Related Problems



Your Learning Community includes the following help:


  • See your academic coordinator for questions and concerns about:

  • academic requirements of the University and your department
    or school

  • procedural matters such as course equivalency substitutions, course prerequisites, or graduation checks

  • See your course mentor/instructor for questions and concerns about:

  • course content

  • your progress in the course
Course-specific questions you might ask a mentor or instructor:

  • “Can you help me understand the difference in meaning between the terms protocols and standards in the Week 9 assignment? They sound like the same thing.”

  • “What can we do about one of the other students in our group project who isn’t doing anything? The rest of us can’t continue until she finishes her part of the project.”
General questions a student might ask a mentor:

  • “When I go to take my proctored exam, will the proctor be able to answer questions I might have about the test?”

  • “Will I be at a disadvantage because I live too far away from you to ever meet with you face-to-face?”

See your lead faculty only when your mentor or instructor directs you to do so or when you have a problem that is not adequately addressed by your mentor or instructor.

Course Name: Object-Oriented Analysis and Design

Prerequisite: COP 3330 Object-Oriented Programming


Course Description




This course introduces you to software engineering and focuses on the important activities that precede the writing of computer code. It will build on many of the concepts and procedures you learned in the previous courses. In the previous courses, you were acquainted with the fundamental concepts of computer science, and began to develop skills in computer programming. You should have learned how to represent problems you encounter and to carefully consider approaches to solutions before beginning to write code.

Thus far, you have dealt with small, relatively well-defined problems. In the world of commerce and industry, technological issues and problems are much larger and more complex. The problems are well beyond the scope of a single individual. Software engineers, in collaboration with others, often spend much of their time brainstorming, discussing, and creating documentation of problems and problem solutions (often incorporating complex diagrams), and a relatively small amount of time writing actual code.



Analysis and design are two of the key activities involved in software development. These activities can be carried out using a number of different methods and tools. Many modern software development methods are based around the object-oriented approach. It is this approach that we will focus upon in this course, and it is assumed you are already familiar with the basic principles of object orientation.

It is important to recognize that there is no one right or wrong way to develop software. Two companies can organize the process of development very differently, yet both may produce successful systems. The overall efficiency of the development process is more critical to the success of the project than the particular method or tool that is used. In order to be efficient, software developers need to give as much consideration to their development process as they do to the product.

In this course, you will gain practical skill in analysis and design that will complement your skills in programming. You will learn about the problems of and approaches to developing large computer systems, and will acquire an understanding of what constitutes a development methodology. You will also experience using computer-aided software engineering (CASE) tools and learn an industry standard modeling language, Unified Modeling Language (UML).

This course is designed to complement the programming course COP 3330: Object-Oriented Programming, in which you have gained the programming experience needed to convert completed designs into computer executable code.

This course can be divided into four learning sections. In the first section (Weeks 1–3) you will focus on systems engineering. In the second section (Weeks 4–7) you will focus on analysis. (Week 9 is the midterm exam, and Week 10 is spring break.) In the third section (Weeks 8, 11–12) you will focus on design. In the final section (Weeks 13–14) you will focus on some issues in software development methodology, including quality control. Use Week 15 for exam preparation.


Overall Course Objectives




After you have completed this course, you should be able to:

  1. Describe and explain the main stages, methods, tools, techniques, and problems involved in systems and software engineering.

  2. Explain the main concepts and goals of analysis and design.

  3. Demonstrate practical skill in the use of an analysis and
    design notation.

  4. Demonstrate technical and communication skills required for working in systems development teams and dealing with .stakeholders.*

Course Requirements




To successfully complete this course you must read assigned texts, listen to lectures, and participate in discussions. Completing the assigned readings before their corresponding lectures and discussions will enable you to raise relevant questions and to improve your learning experience and your grade.

Each week of the course you will be given a set of activities to complete. These activities usually involve taking self-tests from the textbook and consulting the website for other learning resources. Some weeks of the course will also provide “Additional Notes” and Web references to cover material that is not dealt with in the textbook.

Most weeks there are assessments to be completed. These are designed to enhance your learning and demonstrate your understanding of the material. Most weeks you will have to submit assessments to your mentor or TA for grading.

In the first half of the course (prior to the midterm exam), you will find that there are more assessments to complete. In the second half of the course you will be completing a course project. Consequently, there will be fewer assessments in the latter half, as you will be expected to spend time on the course project. You should anticipate an average of 10–15 hours for each week’s activities and assessments.



Discussion: Active participation in discussions and group work is an important part of the course. Your contributions to the class will enrich your own experience and those of your classmates.


Assessment




The overall course grade is determined as follows:







Weekly Assessments

35%










Analysis and Design Project

15%










Midterm Exam

20%







Final Exam

30%









Weekly Assessments

Weekly assessments include assignments that ask you to demonstrate your command of the week’s materials. Each assignment includes the total possible points you can earn and the grading criteria on which your submitted work will evaluated. The total number of obtainable points will vary from week to week. Each week, the points earned on the assignments in the assessments are totaled to give the weekly score. The 35% portion of your grade derived from weekly assessments will be determined by dividing the total assignment points earned by the total number of assignment points possible. The Week 13 assignment will not count towards the final score but will be treated as a substitution assignment; i.e., you can substitute the score on this assignment for your lowest score on the previous assessments. If you miss an assignment, this score can be substituted for the missing assignment.



Exams

The midterm and final exams will be proctored. You will be informed when and where to report for these exams. If the maximum obtainable score for an exam is not 100, it will be converted to a 100-point scale.



Analysis and Design Project

You will work in a group of three or four to produce a requirements analysis document for a new software system. Your grade will be assessed both on the quality of the report and the assessment of your effort by your peers and instructor.

Course Policies




Assessments should be completed using the templates provided on the website. The assessments should be submitted before the due date through the DropBox at the course website using the standard file naming conventions.

Be sure to include the following information on all assessments that you submit:



  • Student ID number

  • Name

  • Section number (for on-campus students) or mentor’s name (for
    distance students)

You will receive assignment grades and feedback through
individual email.

NOTE: Please keep a backup copy of all your work. We cannot assume responsibility for lost items.

Late Policy

Descriptions of each assignment and evaluation criteria will be provided through the course. The dates listed for assessments may change as the semester progresses. If they do, you’ll be notified through the course bulletin board. However, we do expect assessments to be completed on time.

The policy regarding late assessments is 10% penalty for late assessments turned in within 24 hours of due date and 50% penalty for assessments turned in more than 24 hours after the due date. Assessments submitted later than four days after the due date will not be accepted. We use this system even in the event of excusable situations such as minor sicknesses or other unforeseen conflicts. However, any exceptions to this policy are made at our discretion.

Students who miss graded assessments receive a grade of zero. If you are ill or have a serious problem that prevents you from submitting an assignment on the day it is due, please contact your mentor or instructor at once and we will arrange an alternative date. This should be done at least 12 hours before the submission deadline.

The score for the last assignment will be treated as a substitution assignment, which can replace a missed assignment. Those who do not miss an assignment can use their score on the substitution assignment to replace their lowest score.
