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.
Spatial data typesHCL® OneDB® spatial data types are divided into two categories: the base geometry subclasses and the homogeneous collection subclasses.
ST_MultiPoint data typeThe ST_MultiPoint data type is a collection of ST_Points. ST_MultiPoint can define aerial broadcast patterns and incidents of a disease outbreak.

ST_MultiPoint data type

The ST_MultiPoint data type is a collection of ST_Points. ST_MultiPoint can define aerial broadcast patterns and incidents of a disease outbreak.

An ST_MultiPoint is simple if none of its elements occupy the same coordinate space. Just like its elements, it has a dimension of 0. The boundary of a ST_MultiPoint is NULL.
