Abstract: Methods, program products, and systems of synchronizing data while the data is being edited by a user are disclosed. A web application system implementing a notification-based web application framework can allow a user to focus or edit data in a browser on a client device while the data displayed in the browser is being synchronized with data stored on a database server. The user edit and the synchronization can be asynchronous with one another, where editing can occur before a response from the database server is received. Accordingly, user perceived response time is improved over a conventional system where a user must wait for the response from the server before the user can proceed to edit the data.

Abstract: An interactive web application framework allows a user to define user interface and logic of a web application and publish the web application. A first web application system can receive a message from a browser through a second web application system. The message can including metadata indicating that the second web application system received the data from the browser of a user device using a first connection between the second web application system and the browser. The first web application system can send the data to a database server as a request, and receive a response from the database server. Upon receiving the response, the first web application system can cause the second web application system to create a second connection between the second web application system and the browser based on the metadata. The response can be sent to the browser through the second connection asynchronously with the message.

Abstract: An interactive web application framework allows a user to define user interface and logic of a web application and publish the web application. A web application system can receive a database notification from a database server. The database notification can indicate that an update of a user interface item has occurred in a database. The database notification can be generated by the database server in response to a request from a user device. The request can be a request to receive information when any state change occurs at the database server. The web application system can initiate communication with the user device without responding to a specific request requesting the update. The web application system can generate instructions for refreshing the user interface item in a browser, and push the instructions to the user device.
