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.
Regenerate filesAfter you change a BladeSmith project, regenerate the appropriate files.

Regenerate files

After you change a BladeSmith project, regenerate the appropriate files.

For example, if you add a cast to a DataBlade® module, you must regenerate SQL scripts. If the cast has a support routine, you must also regenerate source files. When a node in the generated file category tree on the Generate DataBlade dialog box needs to be generated, it is followed by an asterisk.

BladeSmith uses two processes to regenerate files, depending on the file:

Source code and unit test files. If merging is enabled, BladeSmith merges user changes into the newly generated code.
Visual C++ project, SQL, functional test, and installation files. BladeSmith replaces existing files.
