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 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® modulesThis section suggests how to prepare for developing DataBlade® modules. This overview is intended to act as a map for information resources.
Become familiar with HCL OneDB™ software and documentationFamiliarizing yourself with HCL OneDB™ software and documentation is critical for first-time DataBlade® developers. However, it is important for experienced DataBlade® developers too, because HCL OneDB™ software and documentation are enhanced in each release.
Software requirements for DataBlade® module developmentInstall and become familiar with your database server, HCL OneDB™ Client Software Development Kit, and DataBlade® Developers Kit (DBDK).

Software requirements for DataBlade module development

Install and become familiar with your database server, HCL OneDB™ Client Software Development Kit, and DataBlade® Developers Kit (DBDK).

In addition, if you plan to develop a DataBlade module in Java™, become familiar with J/Foundation and the Java software development kit.

Install the latest version of the HCL OneDB software for your development environment. Although the DataBlade Developers Kit (DBDK) is only available on Windows™, it can generate DataBlade modules for UNIX™ as well as Windows.
