Patent number: 11829360Abstract: Technologies are described for facilitating data workload capture, workload replay, and comparing the performance of a plurality of database systems. A plurality of requests for database operations are received from one or more database clients. The requests for database operations are executed. For the plurality of requests for database operations, execution context information is generated for a plurality of execution contexts. For the plurality of requests for database operations, a plurality of performance measures are generated. The execution context information and the performance measures are stored in a workload capture store, such as a file. The workload capture file is useable to replay the captured workload at a second database system using at least a portion of the execution context information and at least a portion of the performance measures.Type: GrantFiled: February 23, 2022Date of Patent: November 28, 2023Assignee: SAP SEInventors: Chul Won Lee, Juchang Lee, Myunggon Park, Wonyoung Kwak, Jeong Hee Won, Ki Hong Kim, Kyu Hwan Kim, Beomsoo Kim

Patent number: 11709752Abstract: Methods, systems, and computer-readable storage media for receiving a capture file, the capture file holding data representative of a workload executed in a source database system, processing the capture file to provide a replay file, the replay file being in a format that is executable by a replayer to replay the workload in a target database system, the workload including a set of requests represented within the replay file, providing a set of tags associated with the replay file, the set of tags including one or more tags, each tag associated with a request in the set of requests, and during replay of the workload in the target database system: pausing replay of the workload in response to a tag, executing a request associated with the tag, providing replay results specific to the request, and selectively resuming replay of the workload in the target database system.Type: GrantFiled: April 2, 2020Date of Patent: July 25, 2023Assignee: SAP SEInventors: Myunggon Park, Wonyoung Kwak, YoungSeok Hwang, Jihun Kang

Publication number: 20120215847Abstract: The present invention relates to a method for providing Social Network Service (SNS) on the Internet and a system using the same. The present invention is characterized by creating a user tag list constructed with tags that are acquired by a user terminal; forming a social network between the user and other users, based on tags of the user tag list; and creating a diary based on the user tag list and social network associated with tags of the user tag list. While the present invention enables a user to create a diary about one's own life, the present invention provides a social network service (SNS) by utilizing tagging information in the created diary to form a new social network with people or specialists who have the same interests.Type: ApplicationFiled: May 25, 2011Publication date: August 23, 2012Applicant: SNU R&DB FoundationInventors: Mingu Cho, Yanghee Choi, Jinyoung Han, Wonyoung Kwak, Taekyoung Kwon, Jihoon Lee
