SAP Assigned Five Patents

Layered data management, database log parallelization, shared encrypted storage, migration applications from physical machines to virtual machines, automated database archiving

Layered data management
SAP SE, Walldorf, Germany
, has been assigned a patent (9,092,496) developed by Goetz, Oliver, Altrip, Germany, and Barth, Michael, Heidelberg, Germany, for a “layered data management.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A distributed system for administration and storage of data includes a data manager to access a local data store. Several data managers can be chained to form a layered hierarchical structure. All data layers are merged top down to form the resultant data records. Fields can be modified or added in each layer. The system is self organizing in that each data layer only knows about its superordinate data layer. The system provides scalable persistent data storage with centralized data management and the option to locally extend and modify data.

The patent application was filed on April 18, 2006 (11/406,738).

Database log parallelization
SAP SE, Walldorf, Germany
, has been assigned a patent (9,092,475) developed by Schreter, Ivan, Malsch, Germany, for a “database log parallelization.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A plurality of transactions in a data storage application are executed during which log entries according to the plurality of transactions are stored in a plurality of log buffers. The log entries are sequentially written into a current log buffer and the plurality of log buffers are written to a plurality of log partitions according to a round-robin distribution. Thereafter, in response to a data recovery event, a sequential list of the log entries in the log buffers are assembled to generate a log that can be used for data recovery by the data storage application. Related apparatus, systems, techniques and articles are also described.

The patent application was filed on November 7, 2011 (13/290,286).

Shared encrypted storage
SAP SE, Walldorf, Germany
, has been assigned a patent (9,087,205) developed by Kremp, Juergen, Walldorf, Germany, Kiefer, Klaus, Heidelberg, Germany, and Bauer, Uwe, Weinsberg, Germany, for a “shared encrypted storage.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An improved key encryption system is provided for encrypting sensitive data on a shared data store. Various embodiments contemplate a system where a plurality of data clients are connected to one or more shared data stores. A secure data storage facility is provided on one or more of the shared data stores by using an encryption scheme. Encryption keys for decrypting the sensitive data are stored on the same data store as sensitive data which may be decrypted using the encryption keys in question. To provide another layer of protection, the data encryption keys are themselves encrypted using a key encryption key, KEK, which is generated by, and stored in a local persistent data store associated with the data clients.

The patent application was filed on October 11, 2013 (14/051,776).

Migration applications from physical machines to virtual machines
SAP SE, Walldorf, Germany
, has been assigned a patent (9,086,901) developed by Gebhart, Alexander, Akazienweg, Germany, and Bozak, Erol, Vinzentiusstrasse, Germany, for a “migration of applications from physical machines to virtual machines.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Methods and apparatus, including computer program products, are provided for migrating applications from a physical machine to virtualization technology, such as virtual machines. In one aspect, there is provided a computer-implemented method. The method may include receiving, from an agent, information representative of at least one of an application or an operating system at a processor. An image may be created based on the received information. The image may provide a virtual machine including an application. The created image may be provided to a storage device. A virtualization manager may access the storage device and load the created image to implement a virtual machine including the application. Related apparatus, systems, methods, and articles are also described.

The patent application was filed on March 7, 2008 (12/044,891).

Automated database archiving
SAP SE, Walldorf, Germany
, has been assigned a patent (9,081,806) developed by Hegde, Sumanth, and Vijayan, Santosh, Bangalore, India, for a “automated Database Archiving.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Various embodiments of systems and methods of optimizing a database are described herein. Database tables are rated based on at least one of table size and table growth rate. One or more of the database tables are then selected based on the rating of the database tables. Archiving objects for the one or more selected tables are obtained. An archiving object includes one or more archiving programs and defines data related to a business object. The archiving objects are ranked based on dependencies between them. Based on the ranking of the archiving objects, an archiving schedule including an archiving order for the archiving objects is generated. The archiving schedule is then displayed.

The patent application was filed on September 7, 2012 (13/606,028).
