Sequence diagram A  sequence diagram  is an interaction diagram that shows how objects operate with one another and in what order. It is a construct of a message sequence chart. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Sequence diagrams are typically associated with use case realizations in the Logical View of the system under development. Sequence diagrams are sometimes called  event diagrams  or  event scenarios . A sequence diagram shows, as parallel vertical lines ( lifelines ), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner. Diagram building blo...

Class diagram In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modelling. It is used for general conceptual modelling of the systematic of the application, and for detailed modelling translating the models into programming code. Class diagrams can also be used for data modeling. The classes in a class diagram represent both the main elements, interactions in the application, and the classes to be programmed. In the diagram, classes are represented with boxes that contain three compartments: The top compartment contains the name of the class. It is printed in bold and centered, and the first letter is capitalized. The middle compartment contains the attributes of the class. They are ...

Communication diagram  (called  collaboration diagram  in UML 1.x) is a kind of UML  interaction diagram  which shows interactions between objects and/or  parts  (represented as  lifelines ) using sequenced messages in a free-form arrangement. Communication diagram  corresponds (i.e. could be converted to/from or replaced by) to a simple  sequence diagram  without structuring mechanisms such as interaction uses and combined fragments. It is also assumed that  message overtaking  (i.e., the order of the receptions are different from the order of sending of a given set of messages) will not take place or is irrelevant. The following nodes and edges are drawn in a UML communication diagrams:  frame ,  lifeline ,  message . These major elements of the communication diagram are shown on the picture below. The major elements of UML communication diagram. Frame Communication diagrams could be shown wit...

An  event flow  diagram is a kind of diagram that is used to document the  flow of events . The  event flow diagram consists of  event  rule groups and business steps. With an  event flow  diagram, complex  event relationship and related  events  are visually displayed to people.

The Rational Unified Process (RUP) is an iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003. RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs. RUP is a specific implementation of the Unified Process. History Rational Software originally developed the rational unified process as a software process product. The product includes a hyperlinked knowledge-base with sample artifacts and detailed descriptions for many different types of activities. RUP is included in the IBM Rational Method Composer (RMC) product which allows customization of the process. Philippe Kruchten, an experienced Rational technical representative was tasked with heading up the original RUP team. This journey began with the creatio...

What is an Activity Diagram? An activity diagram visually presents a series of actions or flow of control in a system similar to a  flowchart  or a  data flow diagram . Activity diagrams are often used in business process modeling. They can also describe the steps in a  use case diagram . Activities modeled can be sequential and concurrent. In both cases an activity diagram will have a beginning and an Basic Activity Diagram Notations and Symbols Initial State or Start Point A small filled circle followed by an arrow represents the initial action state or the start point for any activity diagram. For activity diagram using swimlanes, make sure the start point is placed in the top left corner of the first column. Activity or Action State An action state represents the non-interruptible action of objects. You can draw an action state in SmartDraw using a rectangle with rounded corners. Action Flow Action flows, also called edges and paths, illustrat...
