Unidata traditionally pays special attention to ensuring data quality. The functions of unified filtering, cleaning and normalization of data coming from different sources, data validation for compliance with specified criteria, data enrichment from internal and external sources are implemented in the platform.
There are two modes of processing – streaming and online. The streaming mode assumes a one-time processing of a large number of records on a data verification request. Accordingly, the result of processing contains the corrected records and a list of errors (if any exist). At the same time, information about the errors found in the platform database with possible receiving this information on the record identifier. In turn, in the online mode there is a synchronous response to a request to record verification. The result of the processing contains the corrected record and, if available, a list of errors.
