Server-side formulas are submitted to the server for execution while a user interacts with the platform; the formula program directly
operates on and is reflected in the database data. Their characteristics are direct database access, high speed and high efficiency.
Data-source interfaces inside a formula come in multi-record and single-record types: multi-record returns the whole set of matching records and drives the formula in a loop, single-record returns just one matching record and drives the formula once; data-source definitions can be nested, so that combined-condition queries can drive the formula.
With server-side formulas, complex data logic can be processed efficiently.
