About This Book

InterSystems IRIS® provides a lightweight Native API for Node.js for direct access to the native data structure of InterSystems databases. Globals are the tree-based sparse arrays used to implement the InterSystems multidimensional storage model. These native data structures provide very fast, flexible storage and retrieval. InterSystems IRIS uses globals to make data available as objects or relational tables, but you can use the Native API to implement your own data structures.

The following chapters discuss the main features of the Native API:

There is also a detailed Table of Contents.

Support for Node.js Relational Access

InterSystems also supports Node.js relational access. The node-odbc open source Node.js module is supported on both Windows and UNIX® based systems. See “Support for Node.js Relational Access” in Using the InterSystems ODBC Driver for details.

Versions of the Native API are also available for Java, .NET, and Python:

The following book is highly recommended for developers who want to master the full power of globals:

  • Using Globals — describes how to use globals in ObjectScript, and provides more information about how multidimensional storage is implemented on the server.
