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.
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.
Build the installationWhen the content and organization of your installation package are complete, build and test it.
Installation type

Installation type

BladePack creates a directory structure in the target directory and copies files into the tree. When you build an interactive installation for a UNIX™ operating system, BladePack includes install and uninstall shell scripts.

When you build a file tree installation, BladePack creates the file tree specified in the project in the target directory. A file tree build is useful for debugging the BladePack project.

After you successfully build an interactive installation, the target directory contains the subdirectories described in the following table.

Table 1. Subdirectories of the target directory
Directory	Description
cdrom	Contains an image of the installation package that can be transferred to distribution media. DataBlade® module developers can rename this directory to the name of the DataBlade module before creating a .tar file. This directory contains an install shell script and other files that the install script uses during installation.
support	Contains copies of files to support the installation, such as project files. Its contents are not distributed with your installation package.
folder_tree	Contains a directory tree containing the contents of all of the directories to be included in the installation package. The contents of this directory are not distributed with your installation package.
tree	The root of a directory tree containing files to be included in the installation package. The tree directory can be used to debug problems in the installation package. The contents of this directory are not distributed with your installation package.
