As much as possible, each test will cover material in the portion of the class that precedes it. However, knowledge is cumulative, and successful completion of a test may require mastery of material covered earlier in the semester. Take tests during the scheduled time. If, due to emergency or illness, you know you will miss a scheduled test, it is your responsibility to let me know ahead of time or worst case, within 24 hours of the missed test.
Make up examinations may be oral, essay, or another format, as determined by the instructor. Project Heavy emphasis is placed on the project.
You need to find a real company to work with. Your stakeholder has to be present for the final presentation. The content of the project is up to you, but it has to involve techniques and software development tools you learned in your MIS and CS classes.
Everything you learn in this class should be applied to the project. Include as many project management tools as possible; for example, one of the first things to create for your project will be a Gantt chart.
Specific guidelines for projects will be discussed in class and posted on Blackboard. Project ideas from the past: I expect everyone to be active contributors to the project, in terms of quality and quantity of input and by helping other team members to do their best. Unprofessional performance and free-riding will be reflected in a student earning a lower grade for the project and its associated deliverables, and may mean that one or more members of the team will receive a failing grade.
Special Topic Presentation Two people who are in different project teams will select a topic, conduct research about the topic, and make a presentation to the class. If appropriate to your topic, include an interactive element to your presentation. In addition, you must create two questions about the material covered in your presentation that are appropriate for inclusion on one of the two tests.
Presentations should be minutes long. PowerPoint slides and questions must be sent to me no later than 9 a. I will post your presentation to Blackboard so that it is available to your classmates. Executive Presence Much of your learning will occur as you prepare for and participate in class discussions.
Most people in business are evaluated on what they say, how they say it, and how they present themselves. The classroom gives you the opportunity to hone your discussion, debating, and impression management skills. Your participation will be evaluated based on what you contribute, not just what you know.
Effective participation has much more to do with quality than quantity. In other words, those who dominate air time without contributing to the advancement of the discussion will not be rewarded.
Executive presence also includes not engaging in activities that show disrespect to me or to your fellow students, including talking on cell phones, texting, or browsing the Internet during class. I realize that individuals come to this class with different backgrounds in technology topics.
The field is constantly changing. No one can possibly know all there is to know. The way to learn is to dive right in. You can expect to receive the following grades for executive presence if your contributions are concise and illustrate critical thinking that is, they go beyond the stated facts. I evaluate performance after each class.
If I believe that preparation is not up to my standards, I reserve the right to administer unannounced quizzes. These quizzes will cover the material assigned for the class session and no make-up quizzes will be given. The quiz scores will be used to partly determine the executive presence grade. Attendance Policy Arrive on time and stay for the duration of each class.
A student may be dropped from a course by the Dean if absences are repeated and the instructor recommends this action. A student can gain re-admission only with permission of both the Dean and the instructor. Missed classes can be for any reason e. Class members including the instructor are to treat each other politely, both in word and deed.
Offensive humor and aggressive personal advances are specifically forbidden.
If you feel uncomfortable with a personal interaction in class, see me for help to solve the problem. Disability Accommodation Students with ADA-documented physical, sensory, emotional or medical impairments may be eligible for reasonable accommodations. Veterans may also be eligible for services.
Please contact the DRC as early in the semester as possible. Alternate format materials Braille, large print or digital are available with advance notice. Ethical Conduct Ethical conduct means communicating honestly and politely with fellow students and with the instructor; it means planning and writing your own projects, and it means relying solely on your own memory to answer test questions.
Students who engage in unethical behavior connected with this class will receive a grade of F for the course and may be referred to other appropriate authorities. Grievance Process Student Code Students who feel they have been unfairly treated [in matters other than i discipline or ii admission, residency, employment, traffic, and parking - which are addressed by procedures separate and independent from the Student Code] may file a grievance through the channels and procedures described in the Student Code: So far, we have only implemented the "debit-from" relationship in one direction- from the Account class to the Transaction class.
Our model does not yet specify in which direction the relationship will be traversed. If we need to traverse the relationship in both directions - getting from the Transaction to the related Account - our implementation will prove insufficient, and some form of double pointer schema may be needed. Much work would have been saved if we had known this fact before we had started writing the code.
Although our Object Model provided a starting point for our implementation, it was not complete, for example new methods have been added to the Account class. Other factors may also influence our choice of implementation: If we do, then a linked-list will prove an inefficient choice of implementation.
Again, it would be very useful to know this type of information before we start trying to implement the relationship. From these points we can see that we need to consider the wider requirements of our system before we can come up with the right implementation of our "debit-from" relationship not to mention the many other classes and relationships that might be required.
We can't produce a good design for a system unless we consider all the required functionality - in detail. Use Cases provide the mechanism for doing this. They provide a useful technique which, in conjunction with Object Modelling, help us to clarify exactly what the system is supposed to do. Let's take a look at the requirements for our banking system: In this case we have identified the following functions: Each type of user typically has their own particular set of requirements for a system: The Use Case diagramming technique allows us to make a first cut at defining the system requirements, and will help us in presenting these requirements back to the users of the system.
It also partitions the system into single atomic business functions, which may be used as a basis for costing the system, or for planning a phased system delivery. In this case each successive phase would deliver further batches of Use Cases.
Further information is still required, however, to tie down the detail of what each businese function does. Use Case Detail provides this information explanatory notes are shown in bold: Use Case Detail: Overdrawn Report Used By: Bank Manager Inputs: Details what information flows from the user to the system for this particular Use Case.
Details what information flows from the system to the external environment, in this case the printer!
What validity checks or constraints apply on the inputs or the internal system as a whole, in some cases. What changes does the Use Case make to the internal system state. Updates the reportedOnDate field of overdrawn accounts.
As work progresses on the Use Cases, the requirements of the system become clearer enabling the Object Model to be updated in parallel, helping us make sure our model and the subsequent implementation in the chosen language contains all the necessary classes and class inter-links. Whilst we're nearer to resolving some of the issues identified at the end of the discussion of implementing Object Models, a number are still outstanding: To sort out the remaining issues we'll need to look in more detail exactly how each Use Case will be implemented, using Sequence Diagrams.
Sequence Diagrams Sequence diagrams, performed on a per Use Case basis, examine the flow of method call calls within a system. Figure 10 - Sequence Diagram for Overdrawn Report Performing a complete analysis requires that each individual Use Case must be examined, although in practise only selected Use Cases may be examined. The Overdrawn Report Use Case is thus implemented as follows: OverdrawnReport method the detail of this is not shown but involves summing up all the Transactions it holds, and checking the date on which it last became overdrawn.
We have added directionality to many of the links e. Of course, we've only looked at one Use Case, so its likely the model will change further as more sequence diagrams are developed. The Overall Process From the above discussion we can see that Use Cases and Sequence Diagrams both add to integrity and completeness of our Object Model, and that a good Object Model provides a firm foundation for a good design, and hence a good implementation of the system.
Typically the Object Model will be incomplete, having only a subset of the class attributes and methods defined. Problem Domain Design is concerned with finalising the detail of the problem domain parts of the Object Model, and results in an Object Model with a complete set of Problem Domain specific classes, attributes and methods.
Typically you would expect to find one controlling dialog box which may use other subsidiary dialogs for each Use Case in the system. Some prototyping may be appropriate at this point in the project. For small projects, prototyping and UI design may be undertaken in parallel with Use Case development. Technical Domain, High Level Design focuses on adding classes to meet the technical needs of the project, and is driven by the technical architecture of the project.
Previous Sequence Diagrams may be updated to confirm the validity of the technical design - in particular you would expect to see GUI classes appearing between the System Boundary and the Problem Domain classes. Finally, Detailed Technical Design, looks at link implementations, detailed data typing of attributes, full specification of all methods including parameters , etc.
The end result is a complete design of the full system. The separation between Problem Domain and the Technical Domain aspects of the system is useful in large projects, allowing the focus of those working on the project to be clearly divided, as summarised in figure Figure 13 - Seperation Of Problem and Technical Domain Components of a System For smaller projects one or two persons for a couple of months the two domains may be merged, if desired.
As mentioned previously, Use Cases may be used in phasing a project; the process shown earlier does not prohibit this. A project with 50 Use Cases could be structured in three phases as shown in figure A number of other UML notations are not covered in this article, however further information can be found on www.
