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.
DBDK InfoShelfThe DataBlade® Developers Kit InfoShelf is designed to help you work with BladeSmith.
DataBlade® Developers Kit TutorialThe Tutorial is a set of exercises that demonstrate how to create extensions to HCL Informix® and package them as DataBlade® modules by using DBDK. Support for DataBlade Developers Kit (DBDK) is removed starting Informix Server 14.10.xC6.
Tutorial exercise 3: Creating row data typesThis exercise demonstrates how to create row data types and user-defined routines that operate on them. This exercise consists of 11 steps. It takes approximately one hour to complete.

About this task

See Building a DataBlade module for detailed instructions on using the Visual C++ workspace file (RowCircle.dsw for this exercise) to compile the source code into the dynamic link library file (RowCircle.bld).

For more information about compiling on UNIX™, see the Informix® DataBlade® Developers Kit User's Guide.
