Patent number: 11237821Abstract: Implementations include, during development of a second version within a development environment, tracing activities to determine development tables, the second version including changes that are incompatible with the first version, the development tables including deploy tables, activation tables, and troubleshooting tables, computing, by a configuration generator, an upgrade configuration based on the development tables, the upgrade configuration defining tables to deploy the changes during an upgrade, the tables being computed based on the development tables, during the upgrade: continuing production use of a first version using a first runtime at least partially including a first data schema, and establishing a second runtime at least partially by defining a second data schema within the database system using the upgrade configuration, the second data schema including the tables, and completing the upgrade by switching production use to the second version from the first version.Type: GrantFiled: November 19, 2020Date of Patent: February 1, 2022Assignee: SAP SEInventors: Kerstin Hoeft, Volker Driesen

Patent number: 10740315Abstract: The present disclosure teaches solutions for transitioning between database system sharing types. In one example, a tenant container includes a read-only table, a first writable table, and a mixed table for storing read-only and writable data. When transitioning to a sharing setup, a shared container is created and a shared table is created in the shared container. Data is copied from the read-only table to the shared table and the read-only table is dropped. A read-only view is created in the tenant container and a second shared table is created in the shared container. Read-only mixed data is copied from the mixed table to the second shared table and deleted from the mixed table, and after the deletion, the mixed table is renamed as the second writable table. A union view is created that provides unified access to the second shared table and the second writable table.Type: GrantFiled: October 26, 2017Date of Patent: August 11, 2020Assignee: SAP SEInventors: Immo-Gert Birn, Kerstin Hoeft, Andrea Neufeld, Uwe Schlarb, Christian Stork, Welf Walter, Volker Driesen

Patent number: 10713277Abstract: The present disclosure teaches solutions for patching content in database systems. In one example, a deployment package for an upgrade of a database system to a new system is received, and the content is deployed to a shared container. Shared objects are identified that are completely stored in the shared container, and partially-shared objects are identified where those objects have a shared portion in the shared container and a tenant portion in one or more tenant containers. First shared content is determined for the shared objects, while second shared content is determined for partially-shared objects. The first and second shared content is then deployed to the shared container. Local content is determined for the partially-shared objects and is deployed to each tenant container. Local content is then identified for local objects and is also deployed to each respective tenant container. Accordingly, both shared and tenant content is deployed.Type: GrantFiled: October 26, 2017Date of Patent: July 14, 2020Assignee: SAP SEInventors: Ulrich Auer, Ralf-Juergen Hauck, Heiko Konrad, Kerstin Hoeft, Florian Thomas, Volker Driesen

Patent number: 10657276Abstract: The present disclosure involves systems, software, and computer implemented methods for enabling multiple system sharing types in multi-tenancy database systems. One example method includes determining a system sharing type configuration for a database system. The system sharing type configuration is one of standard, shared, tenant, or simulated. Tables are created in the database system based on the system sharing type configuration and the table sharing type of each table. Content is deployed to created tables in the database system based on the system sharing type configuration and the table sharing type of each table. Access is provided to at least one application to the database system based on the system sharing type configuration and the table sharing type of each table.Type: GrantFiled: October 26, 2017Date of Patent: May 19, 2020Assignee: SAP SEInventors: Immo-Gert Birn, Kerstin Hoeft, Andrea Neufeld, Uwe Schlarb, Christian Stork, Welf Walter, Volker Driesen

Patent number: 9910871Abstract: A table can be replaced with a view transparently to the application. For example, a data dictionary can specify that the view is to be substituted for the table. At runtime, application operations on the table are redirected to be performed on the view. Validation can be performed to ensure congruence between the table and the view. Can be useful for situations where a view with enhanced functionality is desired to be used in place of the table without re-coding the application.Type: GrantFiled: December 15, 2014Date of Patent: March 6, 2018Assignee: SAP SEInventors: Christian Stork, Kerstin Hoeft, Frank Becker, Bernd Roedel, Thomas Beissel

Patent number: 9378468Abstract: In one embodiment, a method includes defining a parent structure including an extension. A polymorphic structure is defined for the extension. The polymorphic structure is associated with a plurality of client specialization structures, each client specialization being associated with a client in a plurality of clients. During runtime by a computing device, the parent structure is generated with an extension to a client specialization structure associated with one of the plurality of clients where client specialization structures associated with other clients are not visible to the parent structure.Type: GrantFiled: December 27, 2010Date of Patent: June 28, 2016Assignee: SAP SEInventors: Kai Baumgarten, Andreas Blumenthal, Rolf Hammer, Kerstin Hoeft, Jens Lieberum, Helmut Prestel, Andreas S.

Patent number: 9098546Abstract: A new query language can be embedded in a business application programming language (e.g., the ABAP language). A query language consistent with implementations of the current subject matter can be based on a graph data-model of connected business objects (BO) or other data objects and can be designed as an efficient query language embedded into the business application programming language runtime, thereby allowing expression of business logic in a declarative manner.Type: GrantFiled: December 12, 2012Date of Patent: August 4, 2015Assignee: SAP SEInventors: Andreas Gruenhagen, Christian Stork, Kerstin Hoeft, Reiner Singer, Michael Brombach, Marcel Hermanns
