järjestelmäominaisuuksia

Järjestelmäominaisuuksia refers to the characteristics and attributes of a system. These features define how a system operates, its capabilities, and its limitations. They encompass both the functional aspects, which describe what the system does, and the non-functional aspects, which describe how well it performs.

Functional features are the core purposes of the system. For example, in a software system, these might include user authentication, data storage and retrieval, report generation, or specific processing tasks. They are the actions the system is designed to carry out.

Non-functional features, on the other hand, relate to the quality and performance of the system. Common examples include reliability, meaning the system consistently performs as expected without failure. Performance refers to the speed and efficiency with which the system operates, such as response times or throughput. Security is another crucial non-functional feature, addressing the protection of data and resources from unauthorized access or modification. Usability describes how easy and intuitive the system is for users to interact with. Maintainability refers to how easily the system can be modified, updated, or repaired. Scalability indicates the system's ability to handle increasing workloads or user numbers.

Understanding and defining system features is essential for system design, development, and evaluation. It ensures that the system meets its intended goals and user expectations, and that it is robust, efficient, and secure. These features guide the requirements gathering process and serve as benchmarks for testing and validation.
