# Google studio

* Dimensions are data categories. Values may include names, descriptions, date information, or other characteristics of a category.

* Metrics measure the things contained in dimensions. Metrics in your Data Studio reports are aggregated, for example, as sums, counts, or ratios.

* Data set
* A data set is information you’ve collected, possibly generated by or housed in another platform like Google Analytics or BigQuery, or collected in a basic spreadsheet.  “Data set” refers to this underlying data, which lives outside of Data Studio.

* Data source
* A data source is Data Studio’s representation of your data schema. This is where you’ll connect to your data set and choose which dimensions and metrics you want to use in Data Studio reports.
