Methodologies and tools of engineering are utilized alongside computer applications to develop efficient and precise information databases. Computer Systems and Software Engineering: Concepts, Methodologies, Tools, and Applications is a comprehensive reference source for the latest scholarly material on trends, techniques, and uses of various technology applications and examines the benefits and challenges of these computational developments. Highlighting a range of pertinent topics such as utility computing, computer security, and information systems applications, this multi-volume book is ideally designed for academicians, researchers, students, web designers, software developers, and practitioners interested in computer systems and software engineering.
Methodologies and tools of engineering are utilized alongside the technological advancements of computer applications to develop efficient and precise databases of information. The Handbook of Research on Innovations in Systems and Software Engineering combines relevant research from all facets of computer programming to provide a comprehensive look at the challenges and changes in the field.
With information spanning topics such as design models, cloud computing, and security, this handbook is an essential reference source for academicians, researchers, practitioners, and students interested in the development and design of improved and effective technologies. The 45 revised full papers presented together with three keynote presentations were carefully reviewed and selected from a total of submissions. The papers are organized in topical sections on spatial databases, spatio-temporal databases, XML, information modeling, database design, data integration, data warehouse, UML, conceptual models, systems design, method reengineering and video databases, workflows, web information systems, applications, and software engineering.
Conceptualm- eling also plays a prominent rolein various technical disciplines and in the social sciences. The Annual International Conference on Conceptual Modeling referred to as the ER Conference provides a central forum for presenting and discussing current research and applications in which conceptual modeling is the major emphasis.
In keeping with this tradition, ER , the 24th ER Conference, spanned the spectrum of conceptual modeling including research and practice in areas such as theories of concepts and ontologies underlying conceptual m- eling, methods and tools for developing and communicating conceptual models, and techniques for transforming conceptual models into e? Moreover, new areas of conceptual modeling incl- ing Semantic Web services and the interdependencies of conceptual modeling with knowledge-based, logical and linguistic theories and approaches were also addressed.
Class diagrams can also be used to show implementation classes, which are the things that programmers typically deal with. An implementation class diagram will probably show some of the same classes as the logical classes diagram.
The implementation class diagram won't be drawn with the same attributes, however, because it will most likely have references to things like Vectors and HashMaps. A class is depicted on the class diagram as a rectangle with three horizontal sections, as shown in Figure 2. The upper section shows the class's name; the middle section contains the class's attributes; and the lower section contains the class's operations or "methods". Figure 2: Sample class object in a class diagram In my experience, almost every developer knows what this diagram is, yet I find that most programmers draw the relationship lines incorrectly.
For a class diagram like the one in Figure 3,you should draw the inheritance relationship1 using a line with an arrowhead at the top pointing to the super class, and the arrowhead should a completed triangle. An association relationship should be a solid line if both classes are aware of each other and a line with an open arrowhead if the association is known by only one of the classes. Figure 3: A complete class diagram, including the class object shown in Figure 2 Click to enlarge In Figure 3, we see both the inheritance relationship and two association relationships.
The CD and the Band classes both know about each other, and both classes can be associated to one or more of each other. Sequence diagram Sequence diagrams show a detailed flow for a specific use case or even just part of a specific use case.
They are almost self explanatory; they show the calls between the different objects in their sequence and can show, at a detailed level, different calls to different objects.
A sequence diagram is very simple to draw. Across the top of your diagram, identify the class instances objects by putting each class instance inside a box see Figure 4. Optionally, for important messages, you can draw a dotted line with an arrowhead pointing back to the originating class instance; label the return value above the dotted line. Personally, I always like to include the return value lines because I find the extra details make it easier to read.
Reading a sequence diagram is very simple. Start at the top left corner with the "driver" class instance that starts the sequence. Then follow each message down the diagram. Remember: Even though the example sequence diagram in Figure 4 shows a return message for each sent message, this is optional.
The aServlet object is our example driver. The message is labeled generateCDSalesReport, which means that the ReportGenerator object implements this message handler. On closer inspection, the generateCDSalesReport message label has cdId in parentheses, which means that aServlet is passing a variable named cdId with the message. The gen instance then makes calls to the returned aCDReport instance, passing it parameters on each message call.
At the end of the sequence, the gen instance returns aCDReport to its caller aServlet. Please note: The sequence diagram in Figure 4 is arguably too detailed for a typical sequence diagram. However, I believe it is simple enough to understand, and it shows how nested calls are drawn. Also, with junior developers, sometimes it is necessary to break down sequences to this explicit level to help them understand what they are supposed to do.
Statechart diagram The statechart diagram models the different states that a class can be in and how that class transitions from state to state. It can be argued that every class has a state, but that every class shouldn't have a statechart diagram. Only classes with "interesting" states -- that is, classes with three or more potential states during system activity -- should be modeled.
