Extending Informix®Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix® includes many built-in extensions that are fully integrated in the database server. Informix® 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 Informix®.
Informix® 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 describes how to program applications to search data from moving objects in HCL Informix® 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 Informix® Spatiotemporal Search solution consists of built-in functions.

Spatiotemporal Search solution architecture

The Informix® Spatiotemporal Search solution consists of built-in functions.

The Informix 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 Informix TimeSeries solution and the data types, routines, and R-tree indexes from the Informix 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 Informix Spatial extension. You must provide your own visualization software, such as client programs from ESRI.
