Plantuml Language Reference Guide (Version 1.2021.2)
Drawing UML with PlantUML PlantUML Language Reference Guide (Version 1.2021.2) PlantUML is a component that allows to quickly write : • Sequence diagram • Usecase diagram • Class diagram • Object diagram • Activity diagram • Component diagram • Deployment diagram • State diagram • Timing diagram The following non-UML diagrams are also supported: • JSON Data • YAML Data • Network diagram (nwdiag) • Wireframe graphical interface • Archimate diagram • Specification and Description Language (SDL) • Ditaa diagram • Gantt diagram • MindMap diagram • Work Breakdown Structure diagram • Mathematic with AsciiMath or JLaTeXMath notation • Entity Relationship diagram Diagrams are defined using a simple and intuitive language. 1 SEQUENCE DIAGRAM 1 Sequence Diagram 1.1 Basic examples The sequence -> is used to draw a message between two participants. Participants do not have to be explicitly declared. To have a dotted arrow, you use --> It is also possible to use <- and <--. That does not change the drawing, but may improve readability. Note that this is only true for sequence diagrams, rules are different for the other diagrams. @startuml Alice -> Bob: Authentication Request Bob --> Alice: Authentication Response Alice -> Bob: Another authentication Request Alice <-- Bob: Another authentication Response @enduml 1.2 Declaring participant If the keyword participant is used to declare a participant, more control on that participant is possible. The order of declaration will be the (default) order of display. Using these other keywords to declare participants -
Lab 002 – Use Case Modeling.Pdf
TU2943: Information Engineering Methodology Lab Notes, 2009-2010, Faculty of Technology and Information Science, Universiti Kebangsaan Malaysia LAB 2: Introduction to Use Case Modeling OBJECTIVES Familiarize with the concept underlining Use Case Diagram for requirement analysis. Exposure on all elements grouped under UML Case Diagram. Analyze functional requirements and problem statements of an intended system to be able to translate into use case modeling. Be able to document use case description and specifications. INTRODUCTION Definition of Use Case Diagram A Use Case is a set of scenarios describing an interaction between a user and a system. Use Case diagram displays (in symbolic form) the relationship among actor and use cases. Use case represents the system’s functionality, the requirements of the system from the user’s perspective. When to use Use Cases Use cases are used in almost every project. Very helpful in exposing requirements and planning of project. Usually done during the early stages of project. Frequently starts by being loose in terms of connection and accuracy, but as project continues, the use cases are defined better. UML Notation for Use Case Modeling Construct Description Syntax Use Case A description of a set of sequences of actions, including variants, that system performs that yields an observable value to an actor (Booch, 1993). Actor The people or system that provides or receives information from the system; called the stakeholder of the system. Nor Samsiah Binti Sani 1 TU2943: Information Engineering Methodology Lab Notes, 2009-2010, Faculty of Technology and Information Science, Universiti Kebangsaan Malaysia System The boundary between the physical system and Boundary the actors who interact with the physical system. -

Important Java Programming Concepts
Appendix A Important Java Programming Concepts This appendix provides a brief orientation through the concepts of object-oriented programming in Java that are critical for understanding the material in this book and that are not specifically introduced as part of the main content. It is not intended as a general Java programming primer, but rather as a refresher and orientation through the features of the language that play a major role in the design of software in Java. If necessary, this overview should be complemented by an introductory book on Java programming, or on the relevant sections in the Java Tutorial [10]. A.1 Variables and Types Variables store values. In Java, variables are typed and the type of the variable must be declared before the name of the variable. Java distinguishes between two major categories of types: primitive types and reference types. Primitive types are used to represent numbers and Boolean values. Variables of a primitive type store the actual data that represents the value. When the content of a variable of a primitive type is assigned to another variable, a copy of the data stored in the initial variable is created and stored in the destination variable. For example: int original = 10; int copy = original; In this case variable original of the primitive type int (short for “integer”) is assigned the integer literal value 10. In the second assignment, a copy of the value 10 is used to initialize the new variable copy. Reference types represent more complex arrangements of data as defined by classes (see Section A.2). -
Top-Down Software Decomposition – an Approach for Component-Based Design Automation
Top-down Software Decomposition – An Approach for Component-based Design Automation Whitepaper Ionut Cardei Department of Computer Science and Engineering Florida Atlantic University Boca Raton, FL 33431 07/21/2006 Abstract In this whitepaper we summarize the objectives and the technical approach of the Top- down Software Decomposition project and we describe a methodology for improving the quality and reducing the costs of the design process. In our approach product requirements and component semantics are conceptualized in ontologies, providing semantic descrip- tions that are machine readable and can be processed for consistency checking and model synthesis through a process that involves machine reasoning. This paper also provides a brief summary the main technologies involved in this project. The Model Driven Architecture provides the backdrop for a formal software development process and for visual modeling tools. We describe the UML and SysML modeling tools that are commonly used in the industry for requirements analysis and for software design. The main technologies from the semantic web research domain are covered, such as RDF, RDFS, OWL and reasoning engines. 1 Introduction This project has focus on improving the architecture design quality, increasing productivity and reducing the cost of the development process. In this whitepaper we present our approach for automating component-based design through top-down decomposition and we introduce several supporting technologies and tools. We begin by describing the problem we address and the motivation behind our project. As part of the system development cycle, a development iteration begins with requirements spec- ification, where marketing specialists and product managers describe functional requirements, technical specifications, features and use cases in natural language, in a semi-formal format, such as MRDs, UML or SysML, or using requirements management tools such as DOORS 1 [23] or RequisitePro [21].
