Introduction Hexagonal Architecture, also known as Ports and Adapters Architecture, is a powerful architectural pattern used in software design. It is designed to create software systems with loosely coupled components that can easily interact with their environment through ports and adapters. This approach promotes flexibility, testability, and maintainability of software…
Introduction System Structured Analysis and Design Methodology (SSADM) is a widely-used approach for modeling and designing information systems. Data Flow Diagrams (DFDs) are an integral part of SSADM, used to visualize the flow of data within a system. In this beginner's guide, we will introduce you to SSADM DFD Diagrams…
Introduction Data Flow Diagrams (DFDs) are a valuable tool for visualizing and documenting the flow of data within a system. Yourdon DeMarco DFDs, named after their creators Edward Yourdon and Tom DeMarco, provide a structured way to represent how data moves through a system. In this beginner's guide, we'll introduce…
Introduction Yourdon and Coad diagrams are a type of visual modeling tool used in software engineering and system design. They help in representing the structure and behavior of a system or software application. In this beginner's guide, we'll introduce you to Yourdon and Coad diagrams and show you how to…
Introduction Data flow diagrams (DFDs) are a powerful tool for visualizing and understanding how data moves within a business information system. They help analysts and designers to model processes, data stores, data flows, and external entities in a clear and structured way. Gane-Sarson notation, introduced by Chris Gane and Trish…
Introduction The C4 model is a powerful graphical notation technique for modeling the architecture of software systems. Developed by software architect Simon Brown, this method provides a clear and concise way to document and communicate software architecture. In this beginner's guide, we'll introduce you to the C4 model and show…
Introduction SysML, or the Systems Modeling Language, is a powerful tool used for modeling complex systems. Among its various diagram types, the SysML Internal Block Diagram (IBD) is particularly useful for depicting the internal structure of a system component. In this beginner's guide, we'll explore what a SysML Internal Block…
Introduction SysML (Systems Modeling Language) is a powerful tool for designing complex systems, and Parametric Diagrams are a valuable component of SysML that help model and analyze mathematical relationships within a system. In this beginner's guide, we will explore the fundamentals of Parametric Diagrams, their significance, and how to create…
Introduction SysML (Systems Modeling Language) is a powerful tool used for modeling complex systems. One of the fundamental diagram types in SysML is the Block Definition Diagram (BDD). BDDs are used to define the structural aspects of a system, representing the main building blocks or components and their relationships. In…
Introduction SysML (Systems Modeling Language) is a powerful tool for visualizing, specifying, and documenting complex systems. One essential aspect of system modeling is managing requirements effectively. Requirement diagrams in SysML help you capture, organize, and trace system requirements, making it easier to understand and communicate system specifications. In this beginner's…
