TU2943: Information Engineering Methodology Lab Notes, 2009-2010, Faculty of Technology and Information Science, Universiti Kebangsaan Malaysia LAB 5: Interaction Diagram - UML Communication Diagram OBJECTIVES To understand the role of dynamic models in requirement analysis by reading and constructing UML Communication Diagram. INTRODUCTION Communication Diagram (a.k.a. Collaboration Diagram) Communication Diagram provides another way to model a scenario. Essentially is a part of Interaction Diagram (just like Sequence Diagram). Each object is represented by an object icon, and links are used to indicate communication paths on which messages are transmitted. Messages presented in the same way as those in sequence diagram. Formerly known as Collaboration Diagram in UML 1.x specification. Communication Diagram represents a combination of information taken from Use Case, Class and Sequence Diagrams describing both the static structure and dynamic behavior of the system. Comparing and Contrasting: Collaboration and Sequence Both diagrams show the same information: Objects/classes Messages Sequence Conditional Repetition Messages to self Sequence Diagram and Communication Diagram are two views of the same scenario. Collaboration diagrams emphasize who-is-talking-to-who. But the time-ordering of the messages who gets obscured. Sequence diagrams emphasize time-ordering. But the who-is-talking-to-who gets obscured. Use the diagram that you are most comfortable with. Structure and Notation of Communication Diagram Objects are named <an object name>:< its class> . Nor Samsiah Binti Sani 1 TU2943: Information Engineering Methodology Lab Notes, 2009-2010, Faculty of Technology and Information Science, Universiti Kebangsaan Malaysia Either <an object name> or <a class name> can be removed. Collaborations / communications are shown by lines between objects. -

Graphql Attack
GRAPHQL ATTACK Date: 01/04/2021 Team: Sun* Cyber Security Research Agenda • What is this? • REST vs GraphQL • Basic Blocks • Query • Mutation • How to test What is the GraphQL? GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL was developed internally by Facebook in 2012 before being publicly released in 2015. • Powerful & Flexible o Leaves most other decisions to the API designer o GraphQL offers no requirements for the network, authorization, or pagination. Sun * Cyber Security Team 1 REST vs GraphQL Over the past decade, REST has become the standard (yet a fuzzy one) for designing web APIs. It offers some great ideas, such as stateless servers and structured access to resources. However, REST APIs have shown to be too inflexible to keep up with the rapidly changing requirements of the clients that access them. GraphQL was developed to cope with the need for more flexibility and efficiency! It solves many of the shortcomings and inefficiencies that developers experience when interacting with REST APIs. REST GraphQL • Multi endpoint • Only 1 endpoint • Over fetching/Under fetching • Fetch only what you need • Coupling with front-end • API change do not affect front-end • Filter down the data • Strong schema and types • Perform waterfall requests for • Receive exactly what you ask for related data • No aggregating or filtering data • Aggregate the data yourself Sun * Cyber Security Team 2 Basic blocks Schemas and Types Sun * Cyber Security Team 3 Schemas and Types (2) GraphQL Query Sun * Cyber Security Team 4 Queries • Arguments: If the only thing we could do was traverse objects and their fields, GraphQL would already be a very useful language for data fetching. -
Component Diagrams in UML
9. UML Component Diagrams Page 1 of 4 Component Diagrams in UML The previous articles covered two of the three primary areas in which the UML diagrams are categorized (see Article 1)—Static and Dynamic. The remaining two UML diagrams that fall under the category of Implementation are the Component and Deployment diagrams. In this article, we will discuss the Component diagram. Basics The different high-level reusable parts of a system are represented in a Component diagram. A component is one such constituent part of a system. In addition to representing the high-level parts, the Component diagram also captures the inter- relationships between these parts. So, how are component diagrams different from the previous UML diagrams that we have seen? The primary difference is that Component diagrams represent the implementation perspective of a system. Hence, components in a Component diagram reflect grouping of the different design elements of a system, for example, classes of the system. Let us briefly understand what criteria to apply to model a component. First and foremost, a component should be substitutable as is. Secondly, a component must provide an interface to enable other components to interact and use the services provided by the component. So, why would not a design element like an interface suffice? An interface provides only the service but not the implementation. Implementation is normally provided by a class that implements the interface. In complex systems, the physical implementation of a defined service is provided by a group of classes rather than a single class. A component is an easy way to represent the grouping together of such implementation classes. -

Using the UML for Architectural Description?
Using the UML for Architectural Description? Rich Hilliard Integrated Systems and Internet Solutions, Inc. Concord, MA USA [email protected] Abstract. There is much interest in using the Unified Modeling Lan- guage (UML) for architectural description { those techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. IEEE P1471, the Recommended Practice for Architectural Description, represents an emerging consensus for specifying the content of an architectural descrip- tion for a software-intensive system. Like the UML, IEEE P1471 does not prescribe a particular architectural method or life cycle, but may be used within a variety of such processes. In this paper, I provide an overview of IEEE P1471, describe its conceptual framework, and investigate the issues of applying the UML to meet the requirements of IEEE P1471. Keywords: IEEE P1471, architectural description, multiple views, view- points, Unified Modeling Language 1 Introduction The Unified Modeling Language (UML) is rapidly maturing into the de facto standard for modeling of software-intensive systems. Standardized by the Object Management Group (OMG) in November 1997, it is being adopted by many organizations, and being supported by numerous tool vendors. At present, there is much interest in using the UML for architectural descrip- tion: the techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. Such techniques enable architects to record what they are doing, modify or ma- nipulate candidate architectures, reuse portions of existing architectures, and communicate architectural information to others. These descriptions may the be used to analyze and reason about the architecture { possibly with automated support. -
Guidelines for UML Or Sysml Modelling Within an Enterprise Architecture
Guidelines for UML or SysML modelling within an enterprise architecture Mälardalen University Academy of Innovation, Design and Technology Author: Charlie Höglund Email: [email protected] Bachelor of Science in Computer Science/Basic level, 15hp Date: 2017-06-08 Examiner: Jan Carlson Supervisor: Daniel Sundmark Company supervisor: Fredric Andréasson (Volvo Construction Equipment) Abstract Enterprise Architectures (EA) are used to describe an enterprise’s structure in a standardized way. An Enterprise Architecture also provides decision-support when choosing a direction or making changes at different levels of an enterprise, such as the business architecture or technology architecture level. This can involve decisions such as: What kind of enterprise should this be, what kind of technologies should be used for new system developments etcetera. Therefore, using the Unified Modelling Language (UML) or Systems Modelling Language (SysML) together with standardized guidelines that help you decide what to do before, during, and after modelling could be important for producing correct and useful system models, which later on will be used to develop actual systems. At the moment, standardized guidelines of this kind do not really exist. However, there are a lot of information about why you should use UML or SysML, what kinds of UML or SysML diagrams that exist, or what notations to follow when creating a specific UML or SysML diagram. In this thesis, the objective has been to research about the usefulness and creation of standardized guidelines for UML or SysML modelling in an Enterprise Architecture (i.e. mainly intended for the automotive industry domain). For this reason, the two research questions: “how can you create useful standardized guidelines for UML or SysML modelling?” and “what do useful standardized guidelines for UML or SysML modelling look like?” were chosen. -
