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.
DataBlade® Developers KitThe DataBlade® Developers Kit (DBDK) guides contain information about the tools you can use to develop and package DataBlade® modules, which extend the functionality of HCL Informix® databases.
DataBlade® Module Development OverviewThe HCL Informix® DataBlade® module overview serves as an overview of the HCL Informix® DataBlade® module development process.

RoutinesA routine is a stored collection of programming statements that allows you to manipulate data.
User-defined routinesTypically, user-defined routines perform operations specific to the data or application for which they are created and are not based on routines provided with your HCL Informix® database server.

User-defined routines

Typically, user-defined routines perform operations specific to the data or application for which they are created and are not based on routines provided with your HCL Informix® database server.

Users call user-defined routines within SQL statements or through the DataBlade® API. BladeSmith has a wizard to help you define the parameters for user-defined routines.
