Abstract: Analytics can be performed via analytics snippets that are ordinarily used for remote web page navigation, even though the content does not come from a remote server. The snippet can be embedded into a web application that simulates visitation to a simulated web page address by staging a mock environment that reflects properties for the web page, such as the simulated web page address or other arbitrary information. The analytics snippet is then executed in the mock environment. So, the snippet extracts information from the mock environment and reports it to the analytics server. Subsequently, when analytics reports are presented, the simulated web page address is reflected. The true address of the web page can be preserved and presented in the report to conveniently link back to the page in the local environment.

Abstract: Methods and systems are disclosed for data retrieval, from databases to clients, in an environment requiring runtime authorization. In response to a request for T data records, a learning module provides a prediction R of a suitable number of data records to retrieve from a database. Following retrieval of R records or record identifiers, authorization is sought from an authorization service, resulting in A of the records being authorized. The A authorized records are returned to the requesting client, and, if more records are needed, T is decremented and the cycle is repeated. A performance notification is provided to the learning module for training, with respect to providing values of prediction R. The performance notification can be based on a measure of authorization service performance, the number A of authorized records, latency, communication or resource costs, a measure of resource congestion, or other parameters. Variants are disclosed.
