VERSIONED RELATIONAL DATASET MANAGEMENT - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18336743 Titled 'VERSIONED RELATIONAL DATASET MANAGEMENT'
Simplified Explanation
The abstract describes a process for managing a versioned dataset. This involves creating an updated version of the dataset by applying a structured query to a specific version of the dataset. The original data remains unchanged. The dataset catalogue is then updated to include information about the updated version, including the query used and the lineage of the dataset. An affiliation encoding is also updated to indicate which data in the updated version matches the specific version and which data is deleted. Finally, a database view of the updated version is generated by selecting and projecting the relevant data from the original dataset.
Original Abstract Submitted
A versioned dataset is managed. An updated versioned dataset is created by applying a structured query to a specific version of multiple versions of the versioned dataset stored in the backing dataset. Data of the versions including the specific version remain unchanged. A versioned dataset catalogue is updated to include in association with the updated dataset version, the structured query and lineage indicating that the updated versioned dataset includes a successor of the specific version. An affiliation encoding associated with the updated versioned dataset indicating which data of the updated versioned dataset matches data of the specific version and which data of the updated versioned dataset is deleted relative to data of the specific version, is updated. A database view of the updated versioned dataset is generated by selecting rows and projecting columns of the backing dataset corresponding to the updated versioned dataset according to the affiliation encoding.
