What is Metadata?

Metadata is data that summarizes information about other data. In traditional BI, metadata is very structured; anytime the fields change, the metadata has to be updated as well.

However, today’s BI applications are able to work with user-defined fields, eliminating the need for a metadata layer. Data definitions may be changed on the fly. This design allows for a more agile, flexible approach to BI report authoring.
