Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Database Extensions User's GuideThe HCL OneDB™ Database Extensions User's Guide explains how to use the database extensions that come with HCL OneDB™: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, HCL OneDB™ web feature service for Geospatial Data, and SQL packages.
MQ Messaging (WMQ) messaging products provide an infrastructure for distributed, asynchronous communication of data in a distributed, heterogeneous environment. The WMQ message queue allows you to easily exchange information across platforms.
MQ messaging tablesYou use Virtual-Table Interface (VTI) access method to access WMQ queues using table semantics.

MQ messaging tables

You use Virtual-Table Interface (VTI) access method to access WMQ queues using table semantics.

VTI binds tables to WMQ queues, creating transparent access to WMQ objects and enabling users to access the queue as if it were a table. For more information about VTI, see the HCL OneDB™ Virtual-Table Interface Programmer's Guide.
