Softwaresystemarchitektur

Softwaresystem is a cohesive collection of software components and related artifacts designed to fulfill a set of user and business functions. It comprises applications, databases, middleware, interfaces, data models, configuration, and deployment artifacts. A software system can be deployed on one or more hosts and may operate in a distributed environment, interacting with other systems via interfaces such as APIs and event streams.

Typical software systems exhibit modularity and defined boundaries through architecture and patterns such as layered, client–server, service-oriented, or microservice architectures. Components communicate via interfaces, and data is stored in repositories with defined schemas. The runtime environment includes the operating system, containers, cloud services, and orchestration platforms.

Development follows a lifecycle that includes requirements analysis, system design, implementation, testing, deployment, operation, and ongoing maintenance. Modern practice favors iterative, incremental delivery and continuous integration/continuous delivery pipelines. Documentation, version control, and configuration management are essential.

Key quality attributes include functionality, reliability, security, performance, maintainability, portability, and interoperability. Evaluation methods include reviews, testing, and metrics such as defect density and mean time to recovery.

Management of a software system involves stakeholders, governance, and compliance with standards. Standards referenced include general software engineering principles and domain-specific regulations. Versioning, dependency management, change control, and incident management support stability.

Examples include enterprise resource planning systems, customer relationship management systems, and web-based platforms.
