The data can be accessed to support the web application and it can even be accessed when the client is disconnected for a short period of time. There are methodologies for storing data: session storage, local storage and database storage.• Great for Mobile Devices HTML5 could be the solution to faster applications that will be accessible universally across all mobile phones.• New form types and elements will help you certify that the information entered online is completely accurate.
