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.
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.

Introducing the IBM Informix Spatial DataBlade Module
Spatial data types
HCL® OneDB®
spatial data types are divided into two categories: the base geometry subclasses and the homogeneous collection subclasses.
Data exchange formats
You can use several different GIS data exchange formats for spatial data.
R-tree indexes
An index organizes access to data so that entries can be found quickly, without searching every row. The R-tree access method enables you to index multidimensional objects.
Run parallel queries
Running queries in parallel distributes the work for one aspect of a query among several processors and can dramatically improve performance.
Estimate your spatial data
The total amount of space you need for spatial data is equal to the size of spatial tables plus the size of the spatial indexes.
Spatial functions
Use specific spatial data type functions to perform operations on spatial data.
Appendixes
Load and unload shapefile data
Use the
infoshp
,
loadshp
, and
unloadshp
utilities for working with spatial data contained in ESRI shapefiles.
OGC well-known text representation of spatial reference systems
These topics explain how to represent a spatial reference system using a text string and provides information about supported units of measure, spheroids, datums, prime meridians, and projections.

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.
