The CloudDB
component is a Non-visible component that allows you to store data on a Internet connected database server (using Redis software). This allows the users of your App to share data with each other. By default data will be stored in a server maintained by MIT, however you can setup and run your own server. Set the RedisServer(String) property and RedisPort(int) property to access your own server.
@internaldoc The component has methods to store a value under a tag and to retrieve the value associated with the tag. It also possesses a listener to fire events when stored values are changed. It also posseses a sync capability which helps CloudDB to sync with data collected offline.
