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®.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in Informix® databases.
User-Defined Routines and Data Types Developer's GuideThe Informix® User-Defined Routines and Data Types Developer's Guide describes how to define new data types and enable user-defined routines (UDRs) to extend HCL Informix®.

In addition to the extended data types that you explicitly define, you can use the pre-packaged extended data types that are provided. For example, the HCL Informix® DataBlade® module might contain the routines required to support a spherical coordinate system. For more information about HCL Informix DataBlade modules, consult your sales representative or refer to the user guides for the DataBlade modules.
