Patent number: 9697050Abstract: Disclosed embodiments provide a system, machine-readable medium and a method that may generate a session identification for a user session of each of a plurality of users of the computer application. Cookies related to users may be retrieved from external storage using the session identification. A user context may be restored using the retrieved cookies. Functional computing logic may be called based on the restored user context. A state representation may be assembled according to data in a database. Upon completion of functions performed by the called functional computing logic, the user context and the assembled state representation may be stored as a cookie for each of users in external storage. Based on the assembled state representation, user context, and data from the accessed database, HTML code may be generated.Type: GrantFiled: December 22, 2010Date of Patent: July 4, 2017Assignee: SAP SEInventor: Wolfgang Dittrich

Patent number: 9009469Abstract: In one embodiment, a computer-implemented method comprises determining, by a controller, whether a first data store is in an initialization mode. The first data store stores client data. A second data store stores credential data of the first user and credential data of a second user. An application server includes a first secret key store. An in-memory database server includes a second secret key store. The method further comprises, if the first data store is in the initialization mode, receiving, by the controller, from the second user a secret key for encrypting the client data stored in the first data store; and storing, in the first key store, the secret key. The method further comprises, in an operational mode, authenticating the first user based on the credential data of the first user; if the first user is authenticated, processing, in the application server, a user request from the first user.Type: GrantFiled: January 15, 2013Date of Patent: April 14, 2015Assignee: SAP SEInventor: Wolfgang Dittrich

Patent number: 8751469Abstract: A computer-implemented method for providing a stateful computer application to a multitude of users. The method may comprise generating a session identification (e.g., a primary key) for a user session for one user and retrieving a state representation using the session identification. The state of the stateful computer application may be described by a set of user-specific session variables that may be reconstructed from information contained in the state representation. The method may further comprise restoring the set of user-specific session variables using the retrieved state representation and calling functional computing logic based thereon. The functional computing logic may comprise the code of the stateful computer application and the call may provide an updated set of user-specific session variables. Upon completion of functions performed by the called functional computing logic, an updated state representation may be assembled from the updated set of user-specific session variables and stored.Type: GrantFiled: December 22, 2011Date of Patent: June 10, 2014Assignee: SAP AGInventor: Wolfgang Dittrich
