摘要： A query syntax analysis and postprocessing system and method receives a query request specifying values of a data type directed to a database without native support for the queried data type. A query engine or process for receiving a query request defined by a query syntax traverses the query request for a specification of an unsupported value or expression. In a large, distributed database environment, the query request may implicate multiple physical data stores, each having specific formats and recognized syntax. Values of unsupported or non-native types, or expressions that evaluate to an unsupported or non-native type, are identified and replaced with an expression that is recognized by the legacy database.

摘要： Techniques are presented for efficiently provisioning application-agnostic resource access to a variety of applications without modification to the native access control mechanisms of the applications and without transmission of a user's credentials over the network. A user of an application is authenticated by an authorization provider. An access token for the authenticated user is generated. A session password is generated based at least in part on the access token. The session password is applied by the user to the native access control mechanism of an application to facilitate access to resources (e.g., set of subject data) by the application. The resource access is achieved without modification to the native access control mechanism of the application and without transmission of the credentials (e.g., username, password, etc.) of the user over the network.
