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.
Source files generated by BladeSmithWhen you create objects, BladeSmith generates the source files; some file names are prefixed with the name of the DataBlade® module (indicated by project). By default, BladeSmith creates the source files in the src and src\java subdirectories of the directory that contains the BladeSmith project file.
Java™ source code filesBladeSmith generates a ProjectUDRs.java source code file that contains method declarations for all user-defined Java™ routines, cast support routines, and aggregates you defined with BladeSmith. You must edit this file to add the functionality you require.

Java source code files

BladeSmith generates a ProjectUDRs.java source code file that contains method declarations for all user-defined Java™ routines, cast support routines, and aggregates you defined with BladeSmith. You must edit this file to add the functionality you require.

BladeSmith generates the following utility class files that contain utility methods called by BladeSmith-generated routines:

IfmxInStream.java
IfmxOutStream.java
DBDKInputException.java
DBDKOutputException.java
IfmxLog.java
IfmxTrace.java
