And increasingly, process metadata is mined for information on software users or customers, such as what software they’re using and the level of service they’re experiencing. Process metadata can also be used to troubleshoot queries.

Technical metadata tells data professionals how they will need to work with the data-for example, if they can work with it as is, or if they need to transform it for analysis or integration. Technical metadata (also called structural metadata) describes how the data is organized and displayed to users by describing the structure of the data objects-such as tables, columns, rows, indexes, and connections.
