With data coming in from many sources and distributed across different stores, it's getting tougher to find the right data and to know how to use it.<p>On a low level there is for example the "comment on" feature of SQL which won't help with other stores like AWS S3 and thus cannot be a generic solution. Then there are data catalog tools like Azure Data Catalog or Collibra Catalog which seem to be geared towards business users and not as much to developers.<p>I think a good solution needs to support discovery of data (e.g. through searchability and tagging) and allow to explain how to interpret the data (e.g. through detailed comments).<p>What are your best practices or recommendations on tools to use?
