Method, system, and computer program product for simulating an online session

摘要

A method and system for conducting an offline session simulating an online session between a client and server in a network environment. The client imports data and functional logic from the server prior to going offline. The imported functional logic is embedded into a format or document that is capable of being interpreted and performed by the local interface at the client that is used to interact with server during an online session. Whether offline or online, the user utilizes the same local interface at the client to transmit instructions to the functional logic in order to manipulate the data. In an offline session, such instructions cause the imported and embedded functional logic to execute, thereby manipulating the data that is imported at the client. Known synchronization methods may also be used In order to maintain consistency and coherency between the imported data at the client and the database at the server.

主权项

1. A computer program product embodied on a non-transitory computer readable medium, the computer program product including code adapted to be executed by a computer to perform a method comprising:
establishing, by a client device, a connection over a network with a remote system including at least one server, the connection allowing the client device, when online, to communicate with the remote system; using the connection, initiating execution of functional logic at the remote system through a server API solution and an Extensible Markup Language remote procedure call (XML-RPC) to manipulate data in a database of the remote system; sending, by the client to the remote system, a message requesting to enable an offline session; responsive to the message, receiving by the client device from the remote system:
a portion of functional logic executable to access a user-specified portion of the data once such user-specified portion of the data is imported to the client device from the database, so that the client device can conduct the offline session in isolation by enabling the user to modify the user-specified portion of the data imported to the client device by using the imported functional logic,a directory structure, andthe user specified portion of the data from the database, wherein the user-specified portion is selected from the database utilizing criteria defined by the user of the client device; terminating, by the client device, the connection with the remote system in response to the client device being offline; after the terminating of the connection with the remote system by the client device, establishing another connection with the remote system by the client device via the network when the client device returns online; and performing, by the client device, a synchronization process with the remote system via the other connection by sending the modified data from the client device to the database of the remote system.
