In object-oriented (OO) design, responsibilities refer to the tasks or functions that a class or object is responsible for carrying out. The following are different types of responsibilities in OO design : Functional Responsibilities: These are the tasks that a class is responsible for carrying out. For example, a BankAccount class may have functional responsibilities such as deposit, withdraw, and balance inquiry. Informational Responsibilities: These are the tasks related to data managemen...

Explain Uses Case Model in Details

Updated on 13-Apr-2024 17:29:03
Introduction Use Case Model is a popular technique for capturing the functional requirements of a system in a structured way. It is widely used in software engineering and system design to identify and define the interactions between a system and its users, as well as other systems and external actors. The use case model provides a comprehensive view of the system's behavior and functionality, enabling stakeholders to understand how the system works and what it does. In this article, we will exp...

What is a System Sequence Diagram (SSD) ? Why it's Important ?

Updated on 11-Apr-2024 22:38:41
System Sequence Diagrams (SSDs) are a type of UML (Unified Modeling Language) diagram used to describe the interactions between external actors and the system being modeled. They are used to illustrate the flow of events that occur in a system, showing the various processes that take place and how they interact with each other. SSDs are an essential tool in the software development process, helping developers to design and implement software that meets the needs of its users. In this article, we... Read Mores

Explain UP Phases in OOAD

Updated on 10-Apr-2024 15:40:45
UP Phases in OOAD In Object-Oriented Analysis and Design (OOAD), the UP (Unified Process) phases are a series of iterative and incremental steps used to develop software systems. The UP process has four main phases, each with specific goals, activities, and deliverables: Inception Phase: The Inception phase is the first phase in the UP process. In this phase, the project is defined, and the goals of the project are identified. The focus of this phase is to determine whether the project is feas... Read Mores

What is Artifacts ? How its Start in Inception ?

Updated on 28-Mar-2024 8:58:23
What Is Artifacts ?  In the context of software development, artifacts refer to any document or deliverable produced as part of the software development process. These artifacts can take many forms, including diagrams, models, specifications, plans, and reports, among others. The purpose of artifacts is to capture and communicate information about the software being developed, its requirements, design, and implementation, as well as to support collaboration and decision-making among st...

What is Agile Modeling ?

Updated on 28-Mar-2024 8:57:07
Agile modeling is a software development methodology that focuses on producing high-quality software quickly and efficiently. It is an iterative and incremental approach that emphasizes flexibility, collaboration, and customer satisfaction. Agile modeling is based on the Agile Manifesto, a set of principles for software development that values individuals and interactions, working software, customer collaboration, and response to change. In this article, we will discuss agile modeling in detail,... Read Mores

Explain What is Iterative & Evolutionary System Sequence Diagram (SSD) in Details

Updated on 24-Mar-2024 9:00:30
System Sequence Diagram (SSD) is a graphical representation of the interactions between actors and the system under consideration. It is one of the most fundamental diagrams in the Unified Modeling Language (UML) and is used to capture high-level requirements and design of a system. SSDs are an essential part of the requirements analysis phase and are used to capture use cases and user stories. In this article, we will explore two types of SSDs, Iterative SSDs and Evolutionary SSDs, their a... Read Mores

What are Activity Diagram in UML?

Updated on 10-Dec-2023 16:39:44
Activity diagrams are a type of diagram used to describe the flow of activities within a system or process. They are commonly used in software engineering to model complex systems, such as online shopping or automated teller machines (ATMs). In this article, we will explore the history of activity diagrams, their symbols, advantages and disadvantages, and provide examples of how they can be used in various scenarios. History of Activity Diagrams Activity diagrams were first introduced in the lat... Read Mores

Explain an Events, a States & Transition

Updated on 10-Apr-2023 12:56:05
In computer science, state and event are two fundamental concepts that help in designing complex systems and making them more efficient. A state is the condition of a system at a given point in time, while an event is an occurrence that causes a change in that state. States and events are used to model a wide variety of systems, ranging from software applications to physical devices. This article will explore the concepts of states and events in more detail, including their relationship, how the... Read Mores

What are Some Commons Notations Used in UML State Machine Diagram?

Updated on 10-Apr-2023 11:37:28
UML state machine diagrams use various notations to represent different elements and behaviors of the system. Some common notations used in UML state machine diagrams are: 1. States: A state is represented by a rectangle with rounded corners. The name of the state is written inside the rectangle. 2. Transitions: Transitions represent the change of state of an object in response to an event. Transitions are represented by arrows with the name of the triggering event written above the arrow. 3. In... Read Mores
