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® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Spatial Data User's GuideThe 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
HCL OneDB™ spatial solution architecture You can create tables that contain HCL OneDB™ spatial data type columns. You can insert and store geographic features in the spatial columns.
The HCL OneDB™ Web Feature ServiceThe HCL OneDB™ Web Feature Service (WFS) is a transaction service that acts as a presentation layer for spatial data.

The HCL OneDB Web Feature Service

The HCL OneDB™ Web Feature Service (WFS) is a transaction service that acts as a presentation layer for spatial data.

WFS supports the following operations:

Creating new feature instances
Deleting feature instances
Updating feature instances
Querying features that are based on spatial and non-spatial constraints

The HCL OneDB WFS includes a CGI client program and the HCL OneDB server-side function for web programs to send requests to HCL OneDB for geographical features. These geographical features are encoded in the platform-independent, XML-based geography markup language (GML). You can use WFS with the HCL OneDB spatial data types to enable HCL OneDB database servers to manage geographical features. WFS is written to the Open Geospatial Consortium (OGC) standard in document 04-094, Web Feature Service Implementation Specification Version 1.1.0.
