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.
User-Defined Routines and Data Types Developer's GuideThe HCL OneDB™ User-Defined Routines and Data Types Developer's Guide describes how to define new data types and enable user-defined routines (UDRs) to extend HCL OneDB™.
Extend the database server

Extend the database server

This publication discusses extending HCL OneDB™ by using user-defined routines (UDRs) and user-defined data types (UDTs). You can use UDRs and never use a UDT. Conversely, you can use UDTs and never use UDRs. However, many of the ways that you extend data types require that you write routines to support those extensions.

These topics summarize the organization of the section in this publication and describe which portion of the publication you will need to use, depending on your goals.
