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.
Create ActiveX value objectsThis section describes how to use the OneDB® DataBlade® Developers Kit (DBDK) to create ActiveX value objects. This section describes the use of C++ to implement opaque type support routines.
Source files generated by BladeSmithThis section provides an overview of the code that BladeSmith generates for client and server projects.

Source files generated by BladeSmith

This section provides an overview of the code that BladeSmith generates for client and server projects.

BladeSmith generates the following source code for each client and server project:

Makefiles, project files, header files, definitions files, and so on, for both the client project and the server project
A support library for use by the client and server projects

BladeSmith generates the following source code for each ActiveX value object:

Interfaces to the object for use by the client application developer
C++ common code that provides the internal logic for both the client and server projects
Server project opaque type support routines not available as ActiveX custom methods and other code for use by the HCL OneDB™ database server
