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.

Example DataBlade modules

Example DataBlade® modules are included with the DataBlade Developers Kit software.

Example DataBlade modules are in the %INFORMIXDIR%\dbdk\examples directory. The information center has descriptions of the example DataBlade modules with links to readme files and source code.

The example DataBlade modules are frequently updated. The topics you might find covered in the example DataBlade modules include:

Client. Using extended data types with ESQL/C and C++ client programs.
Routines. Using user-defined routines written with the DataBlade API and using MMX technology.
Types. Using extended data types that have support routines written with the DataBlade API, use MMX technology, are implemented as ActiveX value objects, and create user-defined statistics.
