[**Real-time scoring**](../real-time-scoring.md) was the first solution for high-performance scoring. Introduced in early versions of SQL Server 2017 and later updates to SQL Server 2016, real-time scoring relies on CLR libraries that stand in for R and Python processing over Microsoft-controlled functions in RevoScaleR, MicrosoftML (R), revoscalepy, and microsoftml (Python). CLR libraries are invoked using the **sp_rxPredict** stored procedure to generates scores from any supported model type, without calling the R or Python runtime.

[**Native scoring**](../sql-native-scoring.md) is a SQL Server 2017 feature, implemented as a native C++ library, but only for RevoScaleR and revoscalepy models. It is the fastest and more secure approach, but supports a smaller set of functions relative to other methodologies.

Provides scoring on R and Python machine learning models in near real-time. `sp_rxPredict` is a stored procedure provided as a wrapper for the `rxPredict` R function in [RevoScaleR](https://docs.microsoft.com/r-server/r-reference/revoscaler/revoscaler) and [MicrosoftML](https://docs.microsoft.com/r-server/r-reference/microsoftml/microsoftml-package), and the [rx_predict](https://docs.microsoft.com/machine-learning-server/python-reference/revoscalepy/rx-predict) Python function in [revoscalepy](https://docs.microsoft.com/machine-learning-server/python-reference/revoscalepy/revoscalepy-package) and [microsoftml](https://docs.microsoft.com/machine-learning-server/python-reference/microsoftml/microsoftml-package). It is written in C++ and is optimized specifically for scoring operations.

Although the model must be created using R or Python, once it is serialized and stored in a binary format on a target database engine instance, it can be consumed from that database engine instance even when R or Python integration is not installed.
