Patent number: 10740351Abstract: An approach for inter-table parallel refresh in a database management system (DBMS). An inter-table refresher receives DBMS source and target databases comprising source parent and related source child datasets. The inter-table refresher determines a collection of the source parent and the related source child datasets and creates a collection of parent and child refresh segments based on the collection of the source parent and child datasets. The inter-table refresher creates a collection of parent and child refresh batches based on the collection of parent and child refresh segments respectively and outputs an inter-table refresh batch schedule based on the collection of the parent refresh batches and the collection of the child refresh batches where the collection of the parent refresh batches and the collection of the child refresh batches operate concurrently and a current child refresh batch follows the completion of a respective current parent refresh batch.Type: GrantFiled: January 12, 2018Date of Patent: August 11, 2020Assignee: International Business Machines CorporationInventors: Pravin K. Kedia, Nirmal Kumar, Dev K. Sarkar, James D. Spyker
