Emphasize that state, identity and behavior are the key characteristics of an object.Take a moment to explain the graphic on this slide. Attributes are documented on the inside of the doughnut. Operations are documented on the borders, which become clearer to the student as you discuss topics like encapsulation.Note that the doughnut is not part of the UML notation. UML notation is discussed later.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesTrng thi l mt trong cc iu kin m i tng tn ti.

State is not defined by a state attribute or set of attributes. Instead, state is defined by the total of an objects attributes and links. For example, if Professor Clarks status changed from Tenured to Retired, the state of the Professor Clark object would change.

Explain the concept of state to the students.Provide some supplemental state exercises to ensure that the class understands the concept of state. For example an online order (Pending, Approved, Shipped, BackOrdered, Cancelled, etc.) or a cars Cruise Control (Engaged, Disengaged, On, Accelerating, Decelerating).Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesEssentials of Visual Modeling w/ UML 2.0 - Instructor Notesc im th hai ca i tng l hnh vi.

Objects do some interesting things.

Explain the concept of abstraction to the students.A car (a mobile, powered vehicle for transporting people from place to place) is an example of an abstraction if it suppresses less important details.The abstract use of car is not concrete. However, if you describe the car as a 1995 Blue Ford Mustang, then it becomes a concrete manifestation and not an abstraction. Discuss the makings of a good abstraction.

Define the concept of encapsulation to the students.Encapsulation is putting the data bits and operations that manipulate them in the same place. Encapsulation does NOT allow direct manipulation of things that have been encapsulated without using the supplied interface. An example is a cars accelerator. Generally speaking, you put your foot down and the car goes faster. You dont worry about the cables, electronics, engine, and the rest.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesThnh phn kha trong ng gi l giao din cc thng ip (cc phng thc) ca i tng.

However, the way each interprets that operation is unique because the current value for each instrument is dependent on different variables. Point out how the requesting object does not need to know anything about the calculations or the differences. All that it cares about is that the current value is calculated.One of the huge benefits of polymorphism is that the calling object does not need to know what type of object it is calling. In this example, it doesnt care what type of asset it gets the value from, just that it gets the value.

Introduce the concept of generalization. Remember, many of your students are not familiar with this term.Generalization relationships are also permitted between packages. However, packages do not have semantics. Therefore, generalization between packages is not common. According to Grady Booch: The terms inheritance and generalization are, practically speaking, interchangeable. The UML standard calls a relationship generalization so as not to confuse people with language-specific meanings of inheritance. To confuse matters more, some call this an is-a or a kind of relationship (especially those into conceptual modeling in the cognitive sciences). So, for most users, its fair to use either term. For power users, people who care about things like the UML metamodel and specifying formal semantics of the same, the relationship is called generalization and applying such a relationship between two classes, for example, results in the subclass inheriting the structure and operations of the superclass (inheritance is the mechanism).Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesThut ng , t tin v hu du c th thay th cho thut ng cha v con

Make sure students understand that packages are a higher level of abstraction than a class. Everything in your model must reside in a package. Therefore, it is assumed that, at the top level of your model, there is one owning package.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesPhn heading dng cha tn th vi quy tc:[][] c th l : activity - biu hot ng package - biu lp, gi v biu gi communication biu giao tipComponent - biu thnh phn class biu cu trc tng hp deployment -biu trin khai intover Biu tng tc mc tng quan.Object biu i tng state machine biu state machine sd - sequence diagram timing -biu thi gian use case biu use case

The UML 2 specification does not have consistent usage of , for example, the interactions chapter uses sd for all kinds of interaction diagrams (including timing), which is clearly erroneous.

The frame is primarily used in cases where the diagrammed element has graphical border elements, like ports for classes and components (in connection with composite structures), entry/exit points on state machines, and gates/fragments on sequence diagrams. The majority of these are not discussed in this course but will be in OOAD.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesA. An object is an entity with a well-defined boundary and identity that encapsulates state and behavior.B. There are four basic principles of object orientation: abstraction, encapsulation, modularity and phn cp. C. A class is a description of a set of objects that share the same attributes, operations, relationships, and semantics. The class is the static description and the object is the run-time instance of that class.D. An attribute is a named property of a class that describes the range of values that instances of the property may hold. An operation is the implementation of a service that can be requested from any object of the class to affect behavior.E. Polymorphism is the ability to hide many different implementations behind a single interface. For example, a remote control can be used to monitor/support any type of television that relates to a specific interface (whichever interface the remote was designed to be used with). F. Generalization is a relationship among classes where one class shares the structure and/or behavior of one or more classes.G. Without packages, you would end up with large, flat models where all elements would be uniquely named. Packages help you control the elements that compose your system as they evolve at different rates over time.

Provide a high-level definition of object technology. Keep in mind that this is all new to most of your students.Share with the students your excitement about OO. Object technology is not simply the use of an object-oriented language like Java or C++. It is based on the principles of abstraction, modularity, hierarchy, and encapsulation. If an organization is to successfully implement object technology, they must use more than a language. They must also use process, a modeling language (UML), data modeling techniques, and so on.

Offer a comparison between structured design (where many of your students have experience) and Object Orientation (OO).

This slide is not meant to attack the structured design world. Many of the techniques and models that are used in structured design are the basis for the UML and the processes that are used to build OO systems.

However, OO has taken the best techniques from structured design and addressed some of the basic problems to arrive at a better solution.Niklaus Wirth data + algorithms = program Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTTheo Grady Booch, mt thnh vin ca IBM, th mt m hnh cung cp mt khun mu ca h thng.

Emphasize that complex projects outside of the software industry require models. Its inconceivable that a defense contractor would build an airplane as complex as a fighter jet without modeling the airplane first. Why? Because unlike building paper airplanes, the cost of failure is significant. As a general rule, modeling becomes more important as the complexity and expense rises.

Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUT Point out that a major problem with software development is that we often fail to model complex systems before construction. Software engineering is an engineering discipline. Why is it that so many of our projects dont use models like other engineering disciplines such as electrical, civil, and so on? Would anyone work in a high rise that was put together without the benefit of a well thought- out design? Would you drive an automobile that had not been modeled first? Ask the class why they think that software teams dont always model. Note these ideas and address them through the course.

The platform independent viewpoint focuses on the operation of a system while hiding the details necessary for a particular platform. A platform independent view shows that part of the complete specification that does not change from one platform to another. A platform independent view may use a general purpose modeling language, or a language specific to the area in which the system will be used.

The platform specific viewpoint combines the platform independent viewpoint with an additional focus on the detail of the use of a specific platform by a system.Mt khung nhn ca h thng l qu trnh loi b i cc chi tit c th ,rm r c th to nn mt m hnh n gin, tp trung vo nhng vn trng tm bn trong h thng.CIM : Tp trung vo mi trng ca h thng v cc yu cu ca h thng nhng che giu cc chi tit v thc thi v s thc thi ca h thng, gim khong cch gia cc chuyn gia lnh vc v cc chuyn gia cng nghPIM : Tp trung vo thao tc ca h thng, c lp vi nn tngPSM : Tp trung vo chi tit s dng h thng trn mt nn tng nht nh

Remind students that each model should reflect the problem that they are trying to solve.The model of a system comprises many different views of that system. Refer students to the Architectural Blueprints -The 4+1 View of Software Architecture by Phillipe Kruchten. You can find the white paper at http://www-306.ibm.com/software/rational/info/literature/design.jsp. Discuss the views later in this module.Supplement this slide with the following example. To build a home, you would use different models to resolve structural and electrical problems.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNu bn ang xy dng chip my tnh, i khi bn phi cn n rt nhiu mc chi tit khc nhau.

Remember, there are many different ways to view a model of a solution.Again, point out that there is no one mega-model that displays everything about a system.Additional examples from building a home may include examples that the homebuyer may be interested only in the elevation and the floor plan.Obviously, the construction foreman is going to need a more detailed view of the home.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTMt m hnh vt l th thng s khng minh ha c y chc nng ca h thng do gii hn v gi tr ca vt liu xy dng m hnh.

Many interrelated models are needed to accurately describe a system. Introduce the 4+1 views of architecture first. Its important that they understand from the beginning that the models created/read represent a specific view of the system.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTCc h thng phn c xy dng ngy nay cng ngy cng tr nn phc tp. l l do ti sao bn phi m hnh ha h thng.

Introduce the UML. Remember many of your students have no idea what the UML really is.

The next four slides explain how the UML is a language for visualizing, specifying, constructing and documenting.

Stress how the UML is designed to promote communication using pictures rather than text.Using the UML allows the light bulb to go on in the minds of many people. Rather than trying to interpret a textual description of a system design, the UML offers a graphical representation of that same description.In this case, a picture is truly worth a thousand words.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTTrong hon cnh ny, c th c ngha l xy dng cc m hnh chnh xc, r rng v y . c bit , UML gii quyt vn c t cho tt c cc quyt nh quan trng cn phi thc thi v trin khai trong qu trnh phn tch, thit k v thc thi.

The UML can be used to specify detailed or general models.Anyone who has worked on a project where miscommunication occurred appreciates this feature of the UML. The UML allows the modeler to specify their intentions in a clear, unmistakable manner.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesUML khng phi l mt ngn ng lp trnh trc quan.

UML diagrams should be treated as formal project artifacts. Each diagram created by a project team should be treated as an artifact.

Demonstrate that UML was developed as an industry standard with many influences. The UML is not owned and written by Rational.Do not spend a lot of time on this slide. Simply point out one or two contributors of special interest to your audience. For example, for a telephony audience, you might point out Harel and his state charts.Nguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTNguyn Th Thu Trang, SE-FIT-HUTEssentials of Visual Modeling w/ UML 2.0 - Instructor NotesNguyn Th Thu Trang, SE-FIT-HUTKhi bn xy dng m hnh ca bn, bn c th la chn cc khung nhn thc s c ngha, c gi tr i vi cc thnh vin lin i trong d n.

What are their preconceived ideas?Listen closely, as it may help you shape the direction that the class takes.

Its important to record the students concerns at this time. Try to address these issues at the appropriate time in the course. This is a good opportunity to find out if you need to supplement the slides in any particular area.
