DQC is the core module of the Ataccama ONE Data Quality & Governance. Running on top of the DQC engine, there are two user-friendly applications for data stewards and business users.

  • Data Quality Issue Tracker (DQIT)—allows data stewards to resolve various data quality issues that cannot be managed [or fixed/settled] automatically and require their approval or other manual intervention.
  • Data Quality Dashboard (DQD)—enables data stewards and business users to monitor data quality continuously, view its current state, track trends, and use this insight to make informed business decisions.

The diagram below depicts a typical Data Quality process employing these key components:

DQC is an essential tool for complex data quality curation. This domain-agnostic tool is bundled with specific sets of rules and localized dictionaries. Predefined business modules covering cleansing and identity matching for a given business entity include Party, Address and Vehicle.

DQC is able to connect virtually to any database platform via JDBC as well as to various file formats (flat files, XML files, MS Excel spreadsheets, JSONs etc.). This includes formats and sources typically used in the Big Data world such as Avro files, Parquet files, Hive tables and Kafka messages. DQC can provide the outputs of the data processing in various ways—write the standardized/cleansed/deduplicated data to the target data storage (e.g. DWH), calculate data quality indicators (DQIs) for the reporting purposes, or alternatively select records for manual resolution by data stewards/business users and send them to the DQIT application. DQC solutions can be used in both batch and online mode, and any data processing flow can be published as a web service and integrated into various front-end applications, such as a Data Quality Firewall.

DQC is built on a “component” architecture designed to be flexible and customizable while providing ready-to-use data quality modules. Together with task specific modules, DQC can deliver cutting-edge Cleansing, Validation, Match & Merge and Reporting functionalities.
