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™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
DataBlade® Developers KitThe DataBlade® Developers Kit (DBDK) guides contain information about the tools you can use to develop and package DataBlade® modules, which extend the functionality of HCL OneDB™ databases.
DataBlade® Developers Kit User's GuideThe HCL OneDB™ DataBlade® Developers Kit Users Guide describes how to use OneDB® DataBlade® Developers Kit (DBDK) tools to develop and package DataBlade® modules.
Programming DataBlade® modules in Java™This section contains information to help you edit and compile Java™ language source code generated by BladeSmith.
Debug and test DataBlade® Modules written in Java™This section describes debugging and performing functional tests on DataBlade® module routines written in Java™.
Preparing your environmentBefore you can debug or test your DataBlade® module, you must configure your HCL OneDB™ database server.

Preparing your environment

Before you can debug or test your DataBlade® module, you must configure your HCL OneDB™ database server.
