Automated Code Level Lineage




Data lineage is an essential concept in the world of data management. It refers to the ability to trace the origins of a piece of data, from its creation through to its usage and transformation. Data lineage provides transparency and traceability, which are critical for data governance, regulatory compliance, and risk management. In this article, we will explore the various technologies used in data lineage, including mapping tools, harvesting, visualization, knowledge graphs, and machine learning.

Learn more about the primary data lineage techniques including pattern-based, code-based and hybrid data lineage approaches.

data lineage technologies include harvesting, mapping and visualisation

Harvesting Data Lineage Technologies

Harvesting is the process of collecting and extracting data lineage information from various sources, such as metadata repositories, data catalogs, and data management tools. Harvesting can be done manually or automatically, depending on the complexity and volume of data. Manual harvesting involves reviewing documentation and code to identify data sources, transformations, and mappings. However, manual harvesting can be time-consuming and error-prone, especially in complex data environments.

Automated harvesting, on the other hand, leverages technology to extract data lineage information automatically from various sources. Automated harvesting can be done using specialized tools, such as metadata management tools, data catalog tools, or data lineage tools. These tools extract lineage information by analyzing metadata and log files generated by the data management systems. Automated harvesting improves efficiency and reduces errors, but it requires investment in tools and infrastructure.

Mapping Data Lineage Technologies

Mapping is the process of creating a visual representation of data lineage, including the data sources, transformations, and destinations. Mapping is often done using specialized mapping tools, such as ETL (Extract, Transform, Load) tools, data integration tools, or data lineage tools. Mapping tools provide a graphical representation of data lineage, which makes it easy to understand and analyze.

Mapping tools can help identify data quality issues, such as missing or incomplete data, data duplication, or inconsistencies in data formatting. Mapping tools also help identify data lineage gaps, such as missing or incomplete data sources, transformations, or destinations. Mapping tools enable data managers to create a comprehensive view of data lineage, which is critical for regulatory compliance, risk management, and data governance.

Visualizing Data Lineage Technologies

Visualizing is the process of creating interactive and dynamic visualizations of data lineage. Visualizing is often done using specialized visualization tools, such as BI (Business Intelligence) tools, data visualization tools, or data lineage tools. Visualizing provides a user-friendly interface that enables users to explore and analyze data lineage information interactively.

Visualizing tools enable users to drill down into data lineage information, filter and group data, and create custom views. Visualizing tools also enable users to collaborate and share data lineage information with other stakeholders. Visualizing tools provide a more immersive and engaging way to explore and analyze data lineage, which can improve decision-making and data governance.

Knowledge Graphs Data Lineage Technologies

A knowledge graph is a specialized type of database that uses semantic technology to represent data and its relationships. Knowledge graphs provide a powerful way to model and analyze complex data lineage relationships, such as data dependencies, transformations, and impacts. Knowledge graphs enable users to query data lineage information using natural language, which makes it easy to explore and analyze.

Knowledge graphs can be used to create a comprehensive view of data lineage across multiple systems, such as databases, applications, and APIs. Knowledge graphs can also be used to identify data lineage gaps and inconsistencies, such as data duplication or missing data sources. Knowledge graphs provide a more intelligent and efficient way to explore and analyze data lineage, which can improve data governance and regulatory compliance.

Machine Learning Data Lineage Technologies

 Machine learning is a powerful technique for data lineage that enables organizations to automate the process of tracking data lineage. With machine learning, organizations can create predictive models that can identify the relationships between data elements and understand how data is flowing throughout the organization. By using machine learning algorithms, organizations can also identify patterns and anomalies in data lineage, allowing them to quickly identify issues and take corrective action. Machine learning has become an essential tool for data lineage, enabling organizations to track data lineage in real-time and ensure data quality and compliance.
