METADATA PROPAGATION METHOD FOR GRAPH STRUCTURE DATA - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240012858 titled 'METADATA PROPAGATION METHOD FOR GRAPH STRUCTURE DATA

Simplified Explanation

The abstract of this patent application describes a method for determining metadata propagation generated by an Extract, Transfer, Load (ETL) process. The method involves categorizing metadata given to data sources and the ETL process to generalize them. Propagation rules are defined for the generalized metadata and ETL process. Metadata for ETL-converted data is then generated based on the categorization of the generalized metadata and ETL process, following the defined propagation rules.

  • The method categorizes metadata given to data sources and the ETL process.
  • It generalizes the metadata and ETL process.
  • Propagation rules are defined for the generalized metadata and ETL process.
  • Metadata for ETL-converted data is generated based on the categorization and propagation rules.

Potential applications of this technology:

  • Data integration and transformation in ETL processes.
  • Metadata management and propagation in data pipelines.
  • Automation of metadata generation for ETL-converted data.

Problems solved by this technology:

  • Ensures consistent metadata propagation in ETL processes.
  • Reduces manual effort in metadata management.
  • Improves data integration and transformation efficiency.

Benefits of this technology:

  • Streamlines ETL processes by automating metadata generation.
  • Enhances data quality and accuracy through consistent metadata propagation.
  • Reduces errors and inconsistencies in data integration and transformation.


Original Abstract Submitted

a method for determining metadata propagation generated by an extract, transfer, load (etl) process. the method may include categorizing metadata given to data sources to generalize the metadata and categorizing the etl process to generalize the etl process; defining propagation rules for the generalized metadata and generalized etl process; and generating metadata for etl-converted data based on the categorization of the generalized metadata and generalized etl process, and corresponding ones of the propagation rules.
