  • CQRS Pattern

    CQRS (Command Query Responsibility Segregation) and Reactive Programming are two powerful software design paradigms that complement each other when building highly scalable, responsive systems, particularly in the context of complex applications such as e-commerce platforms or real-time data processing systems. CQRS Pattern CQRS is an architectural pattern that separates the handling of commands (which modify…

  • UML Framework

    Unified Modeling Language (UML) is a standardized visual modeling language used in object-oriented software development to specify, visualize, construct, and document the structure and behavior of software systems. Developed by the Object Management Group (OMG), UML offers a suite of diagrams that serve as blueprints for software systems, enabling developers, designers, and stakeholders to communicate…

  • Levels of Software Architecture

    Software architecture defines the fundamental structure of a system, encompassing its components, their relationships, and their interactions. To effectively design complex systems, architects often break down the architecture into distinct levels, each addressing specific aspects of the system. These levels ensure clarity, maintainability, and scalability throughout the software lifecycle. 1. Enterprise Architecture This is the…

  • Technical Requirements Document (TRD)

    The Technical Requirements Document (TRD) is a critical component in the Software Development Life Cycle (SDLC), specifically during the planning and design phases. It bridges the gap between business-oriented requirements (captured in an FRD or BRD) and the technical implementation by defining detailed technical specifications. TRD provides engineers, developers, and architects with precise guidelines to…

  • Software Development Life Cycle (SDLC) Documentation

    The SDLC process is systematically organized into distinct phases, each requiring specific documentation to ensure clarity, traceability, and quality outcomes. Below is a detailed, jargon-rich elaboration of the key documents created in each phase of the SDLC. Phase 1: Planning This foundational stage focuses on establishing the project’s scope, goals, and resource requirements. 1. Project…

  • LLD (Low Level Design)

    Low-Level Design (LLD) is a crucial phase in the software development lifecycle where the system’s components and interactions are designed in detail. LLD focuses on the implementation of the design from a developer’s perspective, detailing class structures, databases, APIs, and algorithms. It is more granular than High-Level Design (HLD) and is critical for developers to…
