Changed metadata

Maintaining the rules of a common interface description is essential when two systems exchange or receive data.

If the metadata of a system is changed by updates without the developers of an exchange process receiving information about it, the flawless functioning of the exchange process is no longer guaranteed. There are errors in data processing and delay in provision of data.

BiG EVAL checks the metadata of data files and interfaces constantly and informs about unforeseen changes.


This test method monitors the schema of a dataset. If changes to tables and individual columns are detected, the system alerts.


As soon as metadata change, BiG EVAL informs via email or directly into your ticketing system.


Control processes based on test results. For example, stop a data import or an ETL process before bad data gets into your system and is processed.
