Data Quality Checks (DQC) Framework

Unlock cost-friendly and unrestricted data quality checking

Since the overwhelming impact of Big Data's advent into financial business services, firms often struggle with complex and disorganized data in their Data Lake and warehouse environments. Poor data quality and lack of standardization often lead to inconsistent or misleading data analytics. Data warehouses can only implement basic data integrity constraints due to volume and performance requirements, thereby making periodic checks a crucial practice. Additionally, many data quality (DQ) checking solutions currently on the market are expensive yet lack optimization and functionality.

What if you could reduce data checking costs and increase productivity without performance constraints?

With Virtusa’s Data Quality Checks (DQC) Framework solution, businesses can conduct cost-efficient DQ checks with an extendible framework using open-source tooling. DQC Framework contains a suite of tools for implementing data quality checking and is built around the popular python-based, open-source data validation, Great Expectations (GE). Our solution uses SQL-based checks on Data Lakes and warehouses so that users can view data results and failures. DQC streamlines the management of testing, automation, and scheduling processes – without the expensive licensing fees attached to commercial ETL (extract, transform, and load) and governance tools.
