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.

HCL Informix Client Software Development Kit

The Informix® Client Software Development Kit (Client SDK) is a set of APIs you can use to develop applications for your Informix database server; they handle communication between the database server and the client application.

Client APIs allow you to write applications in the following languages:

C
Java™
ESQL/C

The Client SDK provides several connectivity products for ODBC-compliant applications and a global language support API.

For a list of current APIs, see the Informix Client Products Installation Guide.
