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.
The ActiveX value objectsThis section provides information for client application developers who are using ActiveX value objects.
Install and use ActiveX value objectsThis section provides some guidelines on installing and using ActiveX value objects.
Install ActiveX value objectsUse BladeManager to install the ProjectS.bld file on your HCL OneDB™ server computer and the ProjectX.dll file on your Windows™ client computer.

Install ActiveX value objects

Use BladeManager to install the ProjectS.bld file on your HCL OneDB™ server computer and the ProjectX.dll file on your Windows™ client computer.

For instructions, see the HCL OneDB DataBlade® Module Installation and Registration Guide.

The ActiveX project you install might also include the following files in the installation package to assist you in locating the CLSID (class identifier) and IID (interface identifier) information for the ActiveX value objects.

Table 1. ActiveX project files
File name	Contains
DkIntf_i.c	Interface identifiers (IIDs) for the ActiveX value object custom interfaces (IRawObjectAccess and ITDkValue)
DkIntf.h	IID declarations for DkIntf_i.c
ProjectX_i.c	Class identifiers (CLSIDs) for the ActiveX value objects provided by the project named Project
ProjectX.h	CLSID declarations for ProjectX_i.c
