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.

Unit test files

Unit test files

Unit tests are SQL files you use to test boundary conditions while debugging your DataBlade® module on Windows™. After you generate unit tests for all your routines with BladeSmith, you add test data to them. If you later regenerate unit tests, the changes you made are merged into the new unit test files. If a unit test is the active window in Visual C++ when you click the Debug DataBlade Module button on the DBDK Visual C++ Add-In toolbar, IfxQuery runs the SQL statements in the unit test file to debug the DataBlade module.

See the Informix® DataBlade Developers Kit User's Guide for more information.
