Gil Fink gave a presentation on creating data-driven HTML5 applications. He discussed storing data in the client-side using HTML5 technologies like Web Storage, AppCache, and IndexedDB. He demonstrated how to use these storage APIs and emphasized that they allow creating offline web applications and decrease server load. Fink concluded that developers can start relying on client-side storages and highlighted resources for learning more about these HTML5 APIs.
