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.
Spatiotemporal Search for Moving Objects User's GuideThe HCL OneDB™ Spatiotemporal Search for Moving Objects User's Guide describes how to program applications to search data from moving objects in HCL OneDB™ databases using the spatiotemporal search extension.
Getting started with spatiotemporal search for moving objectsYou use spatiotemporal searches to track moving objects. You create a spatiotemporal search index on the time-stamped GPS data that is stored in a historian database as time series.
Spatiotemporal Search solution architectureThe HCL OneDB™ Spatiotemporal Search solution consists of built-in functions.

Spatiotemporal Search solution architecture

The HCL OneDB™ Spatiotemporal Search solution consists of built-in functions.

The HCL OneDB database server includes the following functionality for searching spatiotemporal data:

SQL functions to index spatiotemporal data.
SQL functions to query spatiotemporal data.
SQL functions to remove spatiotemporal indexes.

The spatiotemporal search solution builds upon the data types and routines from the HCL OneDB TimeSeries solution and the data types, routines, and R-tree indexes from the HCL OneDB Spatial solution. The following illustration shows how the Spatiotemporal Search solution and related products interact.

The graphic shows the Informix database server with client connectivity and client applications. — Figure 1: Spatiotemporal Search architecture

Spatiotemporal searches return location data as spatial data types from the HCL OneDB Spatial extension. You must provide your own visualization software, such as client programs from ESRI.
