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.
BladePackBladePack creates installation packages for DataBlade® modules and other software products.
Packaging for UNIX™ installationsTo package your DataBlade® module, you add content to a BladePack project, assign components, customize the installation procedure, and build the package.
Manage componentsBladePack allows you to organize your product installation package into three layers: component, subcomponent, and shared component.
Component properties

Component properties

The following table lists the properties of components and subcomponents you define when you create them.

Table 1. Components and subcomponents you define
Property	Description
Name	The name of the component or subcomponent that appears in the left column on the Select Installation Components screen during a custom installation
Description	The description of the component or subcomponent that appears in the right column when the item is selected on the Select Installation Components screen during a custom installation
Inclusion	What type of installation the component or subcomponent is included in: Compact Typical Custom

Shared components have one property: an identifier that is assigned by BladePack. You can edit the identifier; it can be an alphanumeric string up to 128 characters. Make sure that it is unique among shared components. If you change an identifier, be sure to update it for every instance of that shared component.
