Abstract
A computer system operating a web application with offline capabilities, including a web browser, a local web application, a write queue maintained in the local memory and a persistent local database. When the web application needs to perform an operation on a data item, the web application issues a database request to determine if the data item is in the local database. If the data item is not in the local database, the web application issues the data request to the server system. If the data item is in the local database, the web application performs the operation on the data item stored in the database and writes the operation to the write queue along with the identifier of the data item. When a network connection exits between the client device and the server system, the web interface drains the write queue to the server system.
