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.
Spatial data replicationYou can use spatial data types with Enterprise Replication and high-availability clusters.

Spatial data replication

You can use spatial data types with Enterprise Replication and high-availability clusters.

The following conditions must be met to replicate spatial data:

You must ensure that all copies of the spatial_references table are synchronized at all times.
Spatial data type columns in tables that you include in your data replication system must be nullable.
