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.
Estimate your spatial dataThe total amount of space you need for spatial data is equal to the size of spatial tables plus the size of the spatial indexes.

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.

The table size approximations discussed here should be within 100 MB accuracy for large tables; to make estimates of greater precision, refer to the Informix Performance Guide.

To estimate the amount of space you need for spatial data, add the results of the following calculations:
