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™
.
HCL OneDB™
extensions and
DataBlade®
modules
These topics describe how to use built-in database extensions and separately installed
DataBlade®
modules.
Database Extensions User's Guide
The
HCL OneDB™
Database Extensions User's Guide
explains how to use the database extensions that come with
HCL OneDB™
: Large Object Locator, MQ messaging, binary data types, basic text search, node data type,
HCL OneDB™
web feature service for Geospatial Data,
and SQL packages.
Hierarchical data type
The node data type helps to resolve a difficult relational database problem–transitive closure.
Node data type functions
Use these functions in queries involving the node data type.

Large object management
The
Large Object Locator
extension enables you to create a single consistent interface to large objects. It extends the concept of large objects to include data stored outside the database.
MQ
Messaging
(
WMQ
) messaging products provide an infrastructure for distributed, asynchronous communication of data in a distributed, heterogeneous environment. The
WMQ
message queue allows you to easily exchange information across platforms.
Binary data types
The binary18 and binaryvar data types allow you to store binary-encoded strings, which can be indexed for quick retrieval.
Basic Text Search
You can perform basic text searching for words and phrases in a document repository stored in a column of a table.
Hierarchical data type
The node data type helps to resolve a difficult relational database problem–transitive closure.
The node data type for querying hierarchical data
The node data type is an opaque type of variable length up to 256 characters.
Node data type functions
Use these functions in queries involving the node data type.
Ancestors() function
Compare() function
Depth() function
Equal() function
GetMember() function
GetParent() function
Graft() function
GreaterThan() function
GreaterThanOrEqual() function
Increment() function
IsAncestor() function
IsChild() function
IsDescendant() function
IsParent() function
Length() Node function
LessThan() function
LessThanOrEqual() function
NewLevel() function
NodeRelease() function
NotEqual() function
SQL Packages Extension
The SQL packages extension provides SPL routines that you can use in an application that is compatible with database servers other than
HCL OneDB™
.
Regex pattern matching
Regular expressions combine literal characters and metacharaters to define the search and replace criteria. You run the functions from the
HCL OneDB™
Regex extension to find matches to strings, replace strings, and split strings into substrings.
Performing XML Publishing
The
HCL OneDB™
XML User's Guide
includes information about using built-in functions for XML publishing with
HCL® OneDB®
.
Excalibur Text Search
DataBlade®
Module User's Guide
These topics describe the module and how to access and use its components.
Spatial Data User's Guide
The
HCL OneDB™ Spatial Data User's Guide
contains information to assist you in using the
HCL® OneDB®
spatial extension. The
HCL® OneDB®
spatial extension adds custom data types and supporting routines to the server.
Spatiotemporal Search for Moving Objects User's Guide
The
HCL OneDB™ Spatiotemporal Search for Moving Objects User's Guide
describes how to program applications to search data from moving objects in
HCL OneDB™
databases using the spatiotemporal search extension.
TimeSeries Data User's Guide
The
HCL OneDB™ TimeSeries Data User's Guide
contains information to assist you in using the TimeSeries extension with
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.
