Patent number: 11694118Abstract: In accordance with various embodiments, described herein are systems and methods for use of computer-implemented machine learning to automatically determine insights of facts, segments, outliers, or other information associated with a set of data, for use in generating visualizations of the data. In accordance with an embodiment, the system can use a machine learning process to automatically determine one or more outliers or findings within the data, based on, for example, determining a plurality of combinations representing pairs of attribute dimensions within a data set, from which a general explanation or pattern can be determined for one or more attributes, and then comparing particular values for attributes, with the determined pattern for those attributes. Information describing such outliers or findings can be graphically displayed at a user interface, as text, graphs, charts, or other types of visualizations, and used as a starting point for further analysis of the data set.Type: GrantFiled: November 9, 2020Date of Patent: July 4, 2023Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Ashish Mittal, Victor Belyaev, Steve Simon Joseph Fernandez, Gabby Rubin, Alextair Mascarenhas, Samar Lotia, Alvin Raj, John Fuller, Saugata Chowdhury

Patent number: 11475007Abstract: A query optimization system is described that, at runtime, optimizes the execution pipeline generated for a query. Based upon communications between nodes in the execution pipeline, the execution pipeline generated for a query is optimized by modifying the execution pipeline to create a modified execution pipeline. The modified execution pipeline is then executed to execute the query and results obtained for the query. The changes or modifications made to an execution pipeline may include changing the capabilities (e.g., changes to inputs and/or outputs of a node, changing the task(s) or function(s) performed by the node) of one or more nodes within the execution pipeline. The changes may include changing the position of one or more nodes within a directed acyclic graph representing the execution pipeline.Type: GrantFiled: March 8, 2021Date of Patent: October 18, 2022Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Ashish Mittal, Steve Simon Joseph Fernandez, Kenneth Khiaw Hong Eng

Patent number: 11307984Abstract: Optimized techniques are disclosed for sorting variable-length records using an optimized amount of memory while maintaining good locality of references. The amount of memory required for sorting the variable length records is optimized by reusing some of the memory used for storing the variable length records being sorted. Pairs of input runs storing variable length records may be merged into a merged run that contains the records in a sorted order by incrementally scanning, sorting, and copying the records from the two input runs being merged into memory pages of the merged run. When all the records of a memory page of an input run have been processed or copied to the merged run, that memory page can be emptied and released to a cache of empty memory pages. Memory pages available from the cache of empty memory pages can then be used for generating the merged run.Type: GrantFiled: September 28, 2020Date of Patent: April 19, 2022Assignee: Oracle International CorporationInventors: Ashish Mittal, Steve Simon Joseph Fernandez, Kenneth Khiaw Hong Eng

Patent number: 10956379Abstract: Techniques are described that enable the dynamic and automatic life cycle management of database schemas. Temporary database schemas are dynamically and automatically allocated in response to database schema requests. Allocated schemas are also automatically reclaimed upon expiration. A dynamic schema allocation system is provided that is configured to receive database schema requests from one or more clients and dynamically and automatically, substantially free of any manual intervention, serve database schemas in response to the requests. The database schemas may be allocated from multiple database instances available to the dynamic schema allocation system. Attributes specified in a database schema request may be used to find a matching database instance and a schema is allocated for the request from the matching database instance.Type: GrantFiled: April 24, 2018Date of Patent: March 23, 2021Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Steve Simon Joseph Fernandez, Ashish Mittal
