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® module routines in CThis section contains information to help you edit and compile C language source code generated by DataBlade®.

Compile DataBlade module code

This section describes how to compile DataBlade® module code.

BladeSmith generates makefiles for UNIX™ and Visual C++ project files for Windows™. When you compile the generated C source code, you produce a shared object file or dynamic link library, called project.bld, in the source code directory src\OS-platform, where OS-platform is the name of the operating system and platform on which you are compiling. For example, src\WinNT-i386 holds the shared object file compiled on a Windows NT™ computer.

Important: When you generate code in BladeSmith, set the Format property of the DataBlade folder to the correct file format for your operating system (UNIX or DOS). The default is DOS.
