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®.
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\c subdirectories of the directory that contains the BladeSmith project file.
Microsoft™ Visual C++ files

Microsoft Visual C++ files

The project.dsp file is the Visual C++ project file that contains the project information for both C and C++/ActiveX code: for example, a list of the source code files.

The project.dsw file is the Visual C++ workspace file that contains workspace information and refers to the project file for project information. You open the project.dsw file to edit and compile your source code.
