Oracle Database Multilingual Engine

A runtime for executing GraalVM languages in Oracle Database.

Project Overview

Stored procedures, user-defined functions and triggers - in general server-side procedural logic - complement SQL processing and are an important part of many database applications, in particular in enterprise environments. Multilingual Engine (MLE) is a feature of Oracle Database that enables the use of modern programming languages like JavaScript for server-side procedural logic. On the basis of GraalVM, MLE builds a platform for efficient, scalable program execution in Oracle Database that is tightly integrated with processing of relational and non-relational data.

A first version of MLE has been published as part of Oracle Database 21c. It features ad-hoc execution of JavaScript snippets and integration with Oracle APEX. MLE supports all major PL/SQL types and automatically maps to the corresponding JavaScript types and vize-versa. Additionally, the JavaScript code itself can execute PL/SQL and SQL through a built-in JavaScript module.

The Multilingual Engine team at Oracle Labs works on further developing this platform to provide innovative features for database apps.

Senior Director

Matthias Brantner is a Senior Research Director at Oracle Labs. In this role, Matthias leads several projects.

One of those projects is the Oracle Database Multilingual Engine (MLE). MLE is an integration of GraalVM in the Oracle Database which allows dynamic execution of dynamic JavaScript code in the Oracle Database starting 21c.
