REST API is an architectural style that uses HTTP requests for secure data access and exchange over the internet, facilitating communication between two computer systems.
RESTful APIs provide secure, scalable, and simple interfaces for inter-system information exchange over the internet, applicable to various programming languages and platforms.
REST apps have a layer system and uniform UI, while RESTful apps have added features and a REST server for user interactions and performance management.
REST applications feature a uniform user interface, distinguishing them from network-based patterns. Both RESTful and RESTful systems handle data with unique namespaces.
REST APIs provide cacheable/non-cacheable data, improving performance and functionality. RESTful apps allow clients to access cacheable data anytime, anywhere, allowing customization and following enterprise trends.
REST apps maintain no client state, while RESTful servers hide execution, allowing clients to manage application phases and exchange information with distributed objects.
REST devices restrict data access beyond assigned layers, while RESTful apps facilitate data flow across multiple layers, requiring proxies or load balancers for enhanced security and performance.
