Data Quality Tool Recommendation
IRI offers comprehensive data quality management through its Voracity data management platform and component products powered by the SortCL data definition and manipulation program, such as IRI CoSort.
This functionality, outlined below, is designed to ensure that data in structured sources (relational databases, flat files, Excel, ASN.1 CDR files, etc.) remains accurate, consistent, and reliable across different silos and applications:
Profile & Classify
Discovery and Analysis: Utilize data viewers and the metadata discovery wizard in the IRI Workbench (Eclipse GUI) to analyze sources. Data Profiling wizards provide statistical information and data diagrams, check for referential integrity, and perform basic searches.
Advanced Searches and Reports: Multiple data discovery methods, which support value extraction and the features below, can be used to find specific values or fuzzy-matched data based on patterns (plus computational validation), lookups, and NER models. Search logs are generated in multiple formats, and extracted values can be bucketed into flat files.
Data Class and Rule Library: Assign names, search methods, and functions to categories (types) of data you specify. You can associate these data classes with sensitivity-level and privacy law groups, and apply consistent data quality, migration, and masking rules to this data to support data and referential integrity for multiple data source transformations. See this article for more information.
