Description: High-level architecture refers to the conceptual model that defines the structure, behavior, and views of a software system. This approach allows developers and software architects to visualize and plan the organization of a system, facilitating the understanding of its components and their interactions. Through diagrams and models, high-level architecture provides an abstract representation that helps identify the functional and non-functional requirements of the system. Key characteristics include modularity, which allows the system to be divided into more manageable parts; scalability, which ensures that the system can grow and adapt to new requirements; and interoperability, which guarantees that different systems can communicate and work together. High-level architecture is crucial in software project management, as it lays the groundwork for the development, implementation, and maintenance of the system, ensuring that all stakeholders have a clear understanding of the overall project vision.
