  • Data lineage identification and change impact prediction in a distributed computing environment
    Patent number: 10445170
    Abstract: Methods and systems are described for data lineage identification and change impact prediction. Servers capture metadata that defines data objects associated with data sources. The servers determine direct relationships between data sources based upon the captured metadata. The servers identify indirect relationships between the data sources. The servers generate a data lineage across the data sources for the data objects. The servers extract unstructured text from database incident tickets and match the unstructured text to the metadata. The servers generate a multidimensional vector for the data objects based upon the data lineage and the unstructured text. The servers train a classification model using the vectors to predict a change impact score for each data object. The servers receive a request to change a data object. The servers determine a change impact score for the data object. When the score is below a threshold, the servers execute the change.
