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.
Getting started with DataBlade® module developmentThis section provides an overview of DataBlade® module development and describes the resources and tools the HCL OneDB™ database server provides to facilitate development.

Prepare to develop DataBlade modules

This section suggests how to prepare for developing DataBlade® modules. This overview is intended to act as a map for information resources.

To prepare for DataBlade module development, complete these general processes:

If necessary, familiarize yourself with HCL OneDB™ software and documentation (see Become familiar with HCL OneDB software and documentation).
Design your DataBlade module (see Design your DataBlade module).

After you finish your preparations, you can develop your DataBlade module and then have it certified (see Develop your DataBlade module).
