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.
What is a DataBlade® module?A DataBlade® module is a software package that extends the functionality of your HCL OneDB™ database server. The package includes SQL statements and supporting code written in an external language or HCL OneDB™ SPL.

What is a DataBlade module?

A DataBlade® module is a software package that extends the functionality of your HCL OneDB™ database server. The package includes SQL statements and supporting code written in an external language or HCL OneDB SPL.

DataBlade modules can also contain client components. A DataBlade module enables your HCL OneDB database server to provide the same level of support for new data types as it provides for built-in data types.

Users access DataBlade module services in the same way they access database server services: through SQL, SPL, and client programs linked with any of the HCL OneDB client APIs. DataBlade modules can also use the DataBlade API or SQL queries to access data types and routines in other DataBlade modules.

The OneDB DataBlade Developers Kit (DBDK) aids you in developing DataBlade modules. It provides graphical user interfaces to complete tasks, and it generates much of the code you need for your DataBlade module.
