SQL Gateway Overview
See the Table of Contents for a detailed listing of the subjects covered in this document.
The InterSystems SQL Gateway provides access from InterSystems IRIS® data platform to external databases. You can use various wizards to create links to tables, views, or stored procedures in external sources, allowing you to access the data in the same way you access any InterSystems IRIS object:
Access data stored in third-party relational databases within InterSystems IRIS applications using objects and/or SQL queries.
Store persistent InterSystems IRIS objects in external relational databases.
Create class methods that perform the same actions as corresponding external stored procedures.
Connect through either the InterSystems JDBC driver or the InterSystems ODBC driver.
