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 extensions
You 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 Kit
The
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 Guide
The
HCL OneDB™
DataBlade®
Developers Kit Users Guide
describes how to use
OneDB® DataBlade® Developers Kit (DBDK)
tools to develop and package
DataBlade®
modules.

DataBlade Module Development Overview
DataBlade®
Developers Kit User's Guide
The
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 development
This section provides an overview of
DataBlade®
module development and describes the resources and tools the
HCL OneDB™
database server provides to facilitate development.
Design
DataBlade®
modules
This section describes the
DataBlade®
module SQL design issues.
Data model
Data type design
After you have designed a data model for your
DataBlade®
module, you can design its specifics, such as data types to best represent your
DataBlade®
module objects.
Query language interface
The next component in
DataBlade®
module design is the query language interface.
Query processing
To develop a
DataBlade®
module, you need a general understanding of query processing and
HCL OneDB™
SQL. You must also understand the execution environment inside your
HCL OneDB™
database server ̵ the multithreading model, the collection of processes in which
DataBlade®
module routines can execute, and concurrent access to database objects, transactions, and so on.
Interoperability
The interoperability of a
DataBlade®
module refers to how well that module works with your
HCL OneDB™
database server and with other
DataBlade®
modules.
Programming guidelines
Use this section to help you when you write the design specification for your
DataBlade®
module.
Create
DataBlade®
objects by using BladeSmith
Use BladeSmith to create
DataBlade®
modules.
Programming
DataBlade®
module routines in C
This section contains information to help you edit and compile C language source code generated by
DataBlade®
.
Create ActiveX value objects
This section describes how to use the
OneDB® DataBlade® Developers Kit (DBDK)
to create ActiveX value objects. This section describes the use of C++ to implement opaque type support routines.
The ActiveX value objects
This section provides information for client application developers who are using ActiveX value objects.
Programming
DataBlade®
modules in Java™
This section contains information to help you edit and compile Java™ language source code generated by BladeSmith.
Debugging and testing
DataBlade®
modules on UNIX™
This section describes how to debug and perform functional tests for
DataBlade®
modules written in C for
HCL OneDB™
on UNIX™.
Debugging and testing
DataBlade®
modules on Windows™
This section describes how to debug and perform functional tests for
DataBlade®
modules written in C and C++ for
HCL OneDB™
on Windows™.
BladePack
BladePack creates installation packages for
DataBlade®
modules and other software products.
Appendixes
