Ohjelmistokehyssiä, often referred to as software frameworks, are pre-written collections of code, tools, and conventions that provide a standardized structure for developing software applications. They aim to streamline the development process by offering reusable components and abstracting away common, repetitive tasks. Frameworks can be broadly categorized based on their purpose, such as web frameworks, mobile frameworks, game development frameworks, and data science frameworks.

A key characteristic of a software framework is that it dictates the overall architecture and flow of the application. Developers build upon the framework, filling in the specific logic and functionality required for their particular project. This inversion of control, where the framework calls the developer's code rather than the other way around, is a defining feature.

Benefits of using software frameworks include increased development speed, improved code quality and maintainability due to established patterns, enhanced security as many frameworks include built-in security features, and easier collaboration among developers who adhere to a common structure. However, frameworks can also introduce a learning curve, and sometimes the flexibility of a framework might be overkill for very simple projects, potentially leading to unnecessary complexity. Popular examples include React and Angular for front-end web development, Django and Ruby on Rails for back-end web development, and various SDKs for mobile app development.
