This dataset contains transaction and usage data on the Open Data Portal. We are sharing this dataset so that everyone can see what data is being viewed, downloaded and used across the whole website. It is important to us to be transparent and also to allow users to see what datasets others are accessing.

We receive daily log files from our platform provider Datopian which contain every interaction with data on the portal. We load these log files in our data warehouse at the NHSBSA then use a tool called Alteryx to extract, model and output the monthly usage files published here.

We will publish this data on a monthly basis. Each month's data has associated meta data to help you to understand the fields we publish.
