In OMOP CDM, is there a way to log when the the date and time the data get updated?
We are working on this functionality for the Metadata table: http://www.ohdsi.org/web/wiki/doku.php?id=documentation:next_cdm:metadata. Make sure your need is established here.
Thanks! It depends on what type of DB server has been used. It is easy to
get such information for SQL Server and Oracle. But for PostgreSQL, it is
hard.
Well, we are not even talking about the technical implementation, but to define the data model to put that information into some standard place.
