Abstract: In accordance with an embodiment, described herein are systems and methods for providing a remote data gateway for use with an analytics environment, such as, for example, an Oracle Analytics Cloud environment, or a data warehouse or other type of analytics or computing environment. In accordance with an embodiment, the remote data gateway enables secure access by a data analytics warehouse operating in a cloud environment, to a customer's on-premise data, without migrating their on-premise data to the cloud. An on-premise data client exposes a port, which a data analytics remote data gateway server connects to, authenticates itself, and thereafter calls into the client periodically, via a remote data gateway agent, to check for subsequent requests, for example to provide on-premise data to the cloud environment, or to run data analytics on the on-premise data.

Abstract: Making an information retrieval process public, so that it can be followed by others, allows capturing of an interest graph that allows people to learn more about shared interests with other people. This also allows items of interest to a trusted resource (such as an expert) to be identified. These items can then be brought to the attention of other users that share the same interest as the expert. In addition, by keeping track of what particular content a user has already seen, the system can bring items of interest to the user's attention, where the user has not yet seen those items.
