Static Data
Static data refers to information that remains constant and unchanged throughout the execution of a program or system, typically hard-coded or stored in configuration files. It is used for fixed values like constants, configuration settings, lookup tables, or predefined datasets that do not require dynamic updates. This contrasts with dynamic data, which is generated or modified during runtime based on user input or external sources.
Developers should use static data when dealing with immutable values such as mathematical constants (e.g., pi), application settings (e.g., API endpoints in development), or reference data (e.g., country codes) to ensure consistency and reduce runtime overhead. It is essential in scenarios like configuration management, testing with fixed datasets, or implementing lookup mechanisms where performance and predictability are prioritized over flexibility.
