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 5: Using interfacesThis exercise demonstrates how to use interfaces to define how one DataBlade® module depends on another. This exercise has 16 steps. It takes approximately one hour to complete
Generating the Point and Circle DataBlade® modules and open the Point project in Visual C++

Generating the Point and Circle DataBlade modules and open the Point project in Visual C++

About this task

To generate the DataBlade® modules and open the Point project:

Procedure

Click the Circle DataBlade module project window to make it active.
Choose Generate > DataBlade.
With the DataBlade node at the beginning of the file tree selected, click Generate DataBlade.
Click the Point DataBlade module project window to make it active and repeat steps 2 and 3.
After BladeSmith has finished generating code, click MSDev to start Microsoft™ Visual C++ and open the Point.dsw workspace file.

Results

The BladeSmith portion of this exercise is complete; you can exit BladeSmith.
