Abstract

According to an aspect, data asset reconstruction includes receiving a data lineage for a data asset, where the data lineage identifies a data source connected to the data asset by an intermediate process. It is determined whether the intermediate process can be used to reconstruct a lost data asset. Based on determining that the intermediate process can be used to reconstruct the lost data asset, reconstructing the lost data asset with the intermediate process and the data source.

Claims

1. A system for data asset reconstruction, comprising:

a memory having computer readable instructions; and

a processor for executing the computer readable instructions, the computer readable instructions including;

receiving a first data lineage for a first lost data asset, wherein the first data lineage identifies a first data source connected to the first lost data asset by a first intermediate process, the first data source is downstream from the first lost data asset in the first data lineage, and the first intermediate process includes a process that was applied to the first lost data asset to yield the first data source;

determining whether the first intermediate process can be used to reconstruct the first lost data asset;

based on determining that the first intermediate process can be used to reconstruct the first lost data asset and that the first intermediate process is reversible, reconstructing the first lost data asset by reversing the first intermediate process from the first data source to yield the first lost data asset;

identifying a second lost data asset of the first data source upon which reconstruction of the first lost data asset depends;

receiving a second data lineage for the second lost data asset, wherein the second data lineage identifies at least a second data source connected to the second lost data asset by a second intermediate process; and

reconstructing the second lost data asset with the second intermediate process and the second data source prior to reconstructing the first lost data asset.
