Terms in this definition
- FILTER
Returns just those rows of a table that meet a condition. In CALCULATE it handles conditions too complex for a Boolean filter argument, though a Boolean filter is faster whenever one will work.
- Event
Table in Log Analytics where entries from Windows event logs are kept.
- List
Permission on Key Vault secrets allowing a caller to enumerate those in a vault, though their values are not returned.
- DAX
Short for Data Analysis Expressions, the formula language you write measures, calculated columns and row-level security rules in, within tabular semantic models in Power BI, Excel Power Pivot or Analysis Services.
- FIRST
A DAX function available only inside visual calculations. It fetches the value at the start of one axis of the visual's matrix, which makes it handy for comparing each point with the first; its opposite is LAST.
- REST
Short for representational state transfer, the style of HTTP API that Azure services expose.
