QualityStream™ is a system that continuously manages, maintains and improves quality of data by approaching to target data to diagnose quality, draw diagnosed results and analyze them.
After analyzing current level of quality by profiling target database, it manages data by analyzing results of registering (business rule) and scheduling, and by using error correction process.
As a Java-based quality management framework, it supports linkage between UI and servers as well as linkage and integration with quality analysis engine. As it is managed by integrated repository, it can be completely linked with company’s products.
Consisted of modules for analyzing quality of data, it is a core batch module composed of modules of meta data linking and meta information collection engine, and engines of analyzing each function.
It provides user screen for quality analysis and control that displays a variety of functions, such as defining function and scheduling for analysis, process for control, and managing maintenance plans and results.
For improving quality of data, QualityStream™ provides basis for verifying quality of data, focused on quality management index, data quality verification, statistics of quality verification results and maintenance processes.
