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.
Estimating the storage space for the tableThe total size of a spatial table is equal to the column sizes plus the dbspace overhead size multiplied by the number of rows.

Estimating the storage space for the table

The total size of a spatial table is equal to the column sizes plus the dbspace overhead size multiplied by the number of rows.

About this task

To make a rough estimate of the storage space required by the spatial table:

Procedure

Estimate the number of rows in the table.
Add the spatial column size, the non-spatial column size, and the dbspace overhead size together.
Multiply the sum by the estimated number of rows.
