Egenskapsbatteriet

Egenskapsbatteriet, meaning "property battery" in Swedish, refers to a concept in software development, particularly within the domain of object-oriented programming and data modeling. It describes a pattern where an object or entity can dynamically acquire and manage a set of properties that are not rigidly defined in its initial class structure. This allows for greater flexibility and extensibility in how data associated with an object is stored and accessed.

Instead of having a fixed set of attributes pre-defined by the class, an Egenskapsbatteriet allows new properties to be added, modified, or removed at runtime. This is often achieved through mechanisms like a key-value store associated with the object, where each property is represented by a unique key and its corresponding value. This approach is beneficial when dealing with diverse or evolving data requirements where a predefined schema might become cumbersome or inefficient.

Common use cases for the Egenskapsbatteriet pattern include content management systems, e-commerce product catalogs, and user profile management, where the specific attributes of an item or user can vary significantly. It enables a more agile development process by reducing the need for frequent database schema changes or class modifications. The trade-off for this flexibility can sometimes be performance, as accessing dynamically added properties might be less efficient than accessing statically defined ones.
