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.

BladeSmith project windowThe BladeSmith project window is divided into two panes. One pane, called the project view, contains a tree representing the hierarchy of the objects in the project, with folders for files, imported objects, and user-defined objects. The other pane, called the item view, contains information about the object selected in the project view.

BladeSmith project window

The BladeSmith project window is divided into two panes. One pane, called the project view, contains a tree representing the hierarchy of the objects in the project, with folders for files, imported objects, and user-defined objects. The other pane, called the item view, contains information about the object selected in the project view.

The following figure shows a BladeSmith project window.

In the project view, expand or collapse a folder by clicking the expander button next to the node. When you select a node in the project view, the item view displays the content of the node. When you select an object in the project view, the item view displays information about the object.

The information displayed in the item view depends on the type of object selected. The View menu allows you to specify what BladeSmith displays in the item view. You can choose Small Icons, Large Icons, List, or Details from the View menu. When you choose the Details view, BladeSmith lists the properties of the object.

Most objects have property sheets, which allow you to view or edit their properties. To view the property sheet for an object, right-click the object or select the object in either view and then choose Edit > Properties. You can also choose Edit > Update to start the wizard for the selected object.
