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 DataBlade® objects by using BladeSmithUse BladeSmith to create DataBlade® modules.
Generate filesWhen you generate files, BladeSmith creates files that describe the objects you defined in your project.
Opening the project file in Visual C++After you generate your C or C++ source code, you can launch Microsoft™ Visual C++ and open the project workspace file for your DataBlade® module by clicking MSDev on the Generate DataBlade® dialog box.

Opening the project file in Visual C++

After you generate your C or C++ source code, you can launch Microsoft™ Visual C++ and open the project workspace file for your DataBlade® module by clicking MSDev on the Generate DataBlade dialog box.

About this task

You can also open the DataBlade module project in Visual C++ from BladeSmith at any time by choosing Tools > MSDev or clicking the MSDev button in the toolbar.

To launch Visual C++ and open the Visual C++ workspace file:

Procedure

With the project open in BladeSmith, choose Tools > MSDev.
