Best Data Quality Software for AWS Glue

Big Data Quality must always be verified to ensure that data is safe, accurate, and complete. Data is moved through multiple IT platforms or stored in Data Lakes. The Big Data Challenge: Data often loses its trustworthiness because of (i) Undiscovered errors in incoming data (iii). Multiple data sources that get out-of-synchrony over time (iii). Structural changes to data in downstream processes not expected downstream and (iv) multiple IT platforms (Hadoop DW, Cloud). Unexpected errors can occur when data moves between systems, such as from a Data Warehouse to a Hadoop environment, NoSQL database, or the Cloud. Data can change unexpectedly due to poor processes, ad-hoc data policies, poor data storage and control, and lack of control over certain data sources (e.g., external providers). DataBuck is an autonomous, self-learning, Big Data Quality validation tool and Data Matching tool.

Organizations face significant financial losses due to data quality challenges, leading to poor decision-making, unsuccessful initiatives, and eroded customer trust. Instead of relying on conventional reactive methods, DataHub offers a proactive approach to data quality management within your data ecosystem, enabling the identification of potential issues before they affect downstream users. You can set quality assertions on your datasets, such as completeness assessments, freshness service level agreements (SLAs), schema checks, and statistical anomaly identification, receiving immediate notifications when any discrepancies arise. Monitor quality metrics over time to detect trends in degradation and uncover root causes through comprehensive lineage tracking. DataHub presents quality indicators at the point of data discovery, ensuring users are fully informed about the datasets before they make any commitments. Additionally, it facilitates collaboration on data quality challenges with built-in incident management and ownership assignment features.
