UML (Unified Modeling Language) is a diagramming language used for object-oriented programming. It can be used to describe the organization, execution, use, and deployment of a program. Design patterns describe common solutions to programming problems and always use UML diagrams. This document focuses on class diagrams, which show classes, interfaces, and their relationships. It provides examples of how to depict classes with variables and methods, and relationships between classes like inheritance.

2
What is UML?
 UML stands for Unified Modeling Language
 UML is a diagramming language designed for Object-
Oriented programming
 UML can be used to describe:
 the organization of a program
 how a program executes
 how a program is used
 how a program is deployed over a network
 …and more

3
Design Patterns
 Design Patterns describe the higher-level organization
of solutions to common problems
 Design Patterns are a current hot topic in O-O design
 UML is always used for Design Patterns
 Design Patterns are used to describe refactorings
 We will discuss some Design Patterns later on in this
course

4
UML is complex
 UML is a big, complicated diagramming language
 UML comprises at least seven or eight different kinds
of diagrams
 This talk will cover just a tiny bit of one kind of
diagram, the class diagram
 A class diagram is often all that is needed to describe
a particular Design Pattern

5
Class diagrams
 A class diagram shows classes, interfaces, and their
relationships
 We’ll cover most of classes and interfaces, and a few
of the most important relationships

6
Classes
 A class is drawn as a rectangle with two or three
compartments:
Name of the class
Variables [optional]
Methods

7
Variables I
 A variable is written as:
visibility name : type
where:
 + means public visibility
 # means protected visibility
 - means private visibility
 <blank> means default (package) visibility
 Example: +length:int

8
Variables II
 Static variables are underlined
 An initial value can be shown with =value
 Example:
-numberOfEmployees:int=10
means numberOfEmployees is:
 private
 static
 integer
 and has 10 as its initial value

9
Methods
 Methods are written as:
visibility name (parameters) : returnType
where
 visibility uses the same syntax variables (+, -, #, blank)
 parameters are given as name:type
 if the returnType is void, it is omitted
 constructors are preceded by «constructor»
 interfaces are preceded by «interface»
 an ellipsis (…) indicates omitted methods

10
Example of a class
Card
cardId:int
-copy:boolean=false
«constructor» Card(int id)
+isKind(desiredKind:int)
+isSharable():boolean
+toString():String

11
Types of relationships

Class B
extends
class A
C
D

1 to 4 objects
of class D
Factory

creates
Other
kinds of
relations

13
UML tools
 Rational Rose is the “real world” standard; full round-
trip code generation
 Recently acquired by IBM (right under Microsoft’s nose!)
 Together (from Borland) is a lot like Rational Rose
 I haven’t used it in about three years (since before Borland
bought it from TogetherSoft)
 ArgoUML looks interesting (and is open source)
 BlueJ, of course, displays simple UML diagrams
 Drawing programs with UML support
 Visio is a Microsoft tool
 Dia is a freeware clone of Visio

UML (Unified Modeling Language) is a standard modeling language used to specify, visualize, and document software systems. It uses graphical notations to model structural and behavioral aspects of a system. Common UML diagram types include use case diagrams, class diagrams, sequence diagrams, and state diagrams. Use case diagrams model user interactions, class diagrams show system entities and relationships, sequence diagrams visualize object interactions over time, and state diagrams depict object states and transitions. UML aims to simplify the complex process of software design through standardized modeling.

Data Flow DiagramsSinhaa Yash

This document provides an overview of data flow diagrams (DFDs). It describes the key components of DFDs, including processes, flows, stores, and terminators. Processes represent transformations of inputs to outputs, flows represent movement of data, stores represent collections of resting data, and terminators represent external entities. The document distinguishes between physical and logical DFDs, where physical DFDs specify who carries out processes and logical DFDs specify logical activities. It notes that DFDs can be used to provide a context diagram overview of a system and then expanded through leveling to show more detail.

Flow oriented modelingramyaaswin

Flow-oriented modeling represents how data objects are transformed as they move through a system. A data flow diagram (DFD) is the diagrammatic form used to depict this approach. DFDs show the flow of data through processes and external entities of a system using symbols like circles and arrows. They provide a unique view of how a system works by modeling the input, output, storage and processing of data from level to level.

It models members who get discounts and can reserve rentals, and includes reviews customers can provide.

Android intentsSiva Ramakrishna kv

Android Intents allow communication between app components and sharing of data. An Intent specifies an action and can contain data and extras. There are explicit intents, which target a specific component, and implicit intents, which specify an action that may be handled by multiple apps. Components declare intent filters in the manifest to receive implicit intents matching the filter's action, data, and category. When an implicit intent is received, the system resolves matching components by comparing the intent to intent filters.

Ooad unit – 1 introductionBabeetha Muruganantham

Object-oriented analysis and design (OOAD) is a popular approach for analyzing, designing, and developing applications using the object-oriented paradigm. It involves modeling a system as a group of interacting objects at various levels of abstraction. Key concepts in OOAD include objects, classes, attributes, methods, encapsulation, inheritance, polymorphism, and relationships like association, aggregation, and composition. Common OOAD techniques include use case diagrams, which show interactions between actors and the system, and class diagrams, which describe the structure and behavior of system objects and their relationships.

INTRODUCTION TO UML DIAGRAMSAshita Agrawal

UML stands for Unified Modelling Language. UML is a standard language for specifying, visualizing, constructing, and documenting a system in which software represents the most significant part. UML is different from the other common programming languages like C++, Java, COBOL etc. UML is a pictorial language used to make software blue prints. UML can serve as a central notation for software development process. Using UML helps project teams communicate, explore potential designs, and validate the architectural designs of software. UML diagrams are made using notation of things and relationships. The building blocks of UML can be defined as: Things Relationships Diagrams Things: Things are the most important building blocks of UML. Things can be: Structural Behavioral Grouping Annotational The Structural things define the static part of the model. They represent physical and conceptual elements. Following are the brief descriptions of the structural things. Class: Class represents set of objects having similar responsibilities. Interface: Interface defines a set of operations which specify the responsibility of a class. Collaboration: Collaboration defines interaction between elements. Use case: Use case represents a set of actions performed by a system for a specific goal. Component: Component describes physical part of a system. Node: A node can be defined as a physical element that exists at run time. A behavioral thing consists of the dynamic parts of UML models. Following are the behavioral things: Interaction: Interaction is defined as a behavior that consists of a group of messages exchanged among elements to accomplish a specific task. State machine: State machine is useful when the state of an object in its life cycle is important. It defines the sequence of states an object goes through in response to events. Events are external factors responsible for state change.

Use case diagramCity University

The document discusses use case diagrams in UML modeling. It defines key components of use case diagrams including use cases, actors, the system boundary, and relationships like include, extend, and generalization. It provides examples of how to construct a use case diagram based on system functions and user goals. Specific use case diagram examples shown include an online ordering system and a vending machine.

Entity Relationship Diagramssadique_ghitm

Entity Relationship Diagrams (ERDs) are conceptual data models used in software engineering to model information systems. ERDs represent entities as rectangles, attributes as ellipses, and relationships as diamonds connecting entities. Attributes can be single-valued, multi-valued, composite, or derived. Relationships have cardinality like one-to-one, one-to-many, many-to-one, or many-to-many. Participation constraints and Codd's 12 rules of relational databases are also discussed in the document.

UMLiQra Rafaqat

UML (Unified Modeling Language) is a standard language for specifying, visualizing, and documenting software systems. It uses various diagrams to model different views of a system, such as structural diagrams (e.g. class diagrams), behavioral diagrams (e.g. sequence diagrams), and deployment diagrams. The key building blocks of UML include things (classes, interfaces, use cases), relationships (associations, generalizations), and diagrams. UML aims to provide a clear blueprint of software systems for both technical and non-technical audiences.

object oriented methodologiesAmith Tiwari

Object Oriented Methodologies discusses several object-oriented analysis and design methodologies including Rambaugh's Object Modeling Technique (OMT), Booch methodology, and Jacobson's Object-Oriented Software Engineering (OOSE). OMT separates modeling into object, dynamic, and functional models represented by diagrams. Booch methodology uses class, object, state transition, module, process, and interaction diagrams. OOSE includes use case, domain object, analysis object, implementation, and test models.

The document discusses the Unified Modeling Language (UML). UML is a general-purpose modeling language used to specify, visualize, construct, and document software systems. It captures decisions and understanding about systems that must be constructed. The goals of UML included developing a modeling language that could be used across different domains and development methods. UML has three main building blocks - things, relationships, and diagrams. Things represent elements in a model like classes, components, and use cases. Relationships connect things and show dependencies, generalizations, and associations. Diagrams provide different views of UML models, including structural diagrams and behavioral diagrams.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak

As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.

Exploring Code Comprehension in Scientific Programming: Preliminary Insight...University of Hawai‘i at Mānoa

This presentation explores code comprehension challenges in scientific programming based on a survey of 57 research scientists. It reveals that 57.9% of scientists have no formal training in writing readable code. Key findings highlight a "documentation paradox" where documentation is both the most common readability practice and the biggest challenge scientists face. The study identifies critical issues with naming conventions and code organization, noting that 100% of scientists agree readable code is essential for reproducible research. The research concludes with four key recommendations: expanding programming education for scientists, conducting targeted research on scientific code quality, developing specialized tools, and establishing clearer documentation guidelines for scientific software. Presented at: The 33rd International Conference on Program Comprehension (ICPC '25) Date of Conference: April 2025 Conference Location: Ottawa, Ontario, Canada Preprint: https://arxiv.org/abs/2501.10037

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik

Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe. We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved? Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.
