The data lineage diagram can show us which datasets are being used. These reports are created by using several datasets that are generated within the organization. These reports are used to make decisions for the growth of the organization. In an organization, the data is used to create several reports. It helps in classification the data so that we can understand which data policies need to define against the data so that we can protect our sensitive data. And before that, it is also necessary to understand what information does the data contains. We always need to define some access policies to the data. Know the owner of data is most important as it gives clarity that who is maintaining that data and to whom the user should contact in case of any problem with the correction. The data owner has the responsibility to store the data into the appropriate location and to grant access to the data. There is also some parameter which needs to define at the time of data creation. From the it, we can track this and find out who is using this data. One of them is who is using the data and where? When we have the visuals of the data lineage it is easy for us to find out the answers to these questions. While analyzing the data, there are lots of question which comes into Data Analyst’s mind. The 5 W’s of Data Lineage are described below: Who is using the Data? Click to explore about, Big Data Governance Tools What are the 5 W’s of it? In the case when we have some failed jobs, it can help us to find the target tables and fields affected which are being used in the reports.īig Data Governance is the process and management of data availability, usability, integrity, and security of data used in an enterprise. When we need to troubleshoot for any of the wrong reports, lineage can help us to identify which process and jobs are involved in creating that particular report. It can help the business user to check whether the data is accurate or not. Example: there is some data source that includes data fields named sales and gender if the user needs to find the reports of the bases of these data fields. It provides transparency to the user who is responsible for that particular data asset.ĭata lineage helps a business user to find the reports based on any particular data fields or column. It helps the person to identify the least and most usable data assets in an ETL job. To play the role of a data steward, the person needs to know everything about the data which is being used in an organization. While dealing with complex reports, it helps in the identification of the data source which should be used in that report. It also enables us to check for any changes in some of the data fields such as column deletion, renamed or added. It can help an ETL developer to trace any bug/error within the ETL job. ETL job is a function where we need to extract data from any defined data source and put it into another location after applying some data transformation on the collected data. The importance of Data Lineage is listed below: For an ETL DeveloperĮTL stands for Extract, Transform, and Load. Click to explore about, Data Catalog for Snowflake Why it is important? We will discuss these questions in a later section.Īn organized record of data assets that uses metadata to help organizations manage their data.
