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.
You 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.
The 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.
The HCL Informix® DataBlade® module overview serves as an overview of the HCL Informix DataBlade module development process.
These topics describe how to use built-in database extensions and separately installed DataBlade® modules.
The Informix® DataBlade® API Programmer's Guide describes information about the DataBlade API, the C-language application programming interface (API) provided with HCL Informix.
The Informix® DataBlade® API Function Reference describes the DataBlade API functions and the subset of Informix ESQL/C functions that the DataBlade API supports.
The DataBlade® Developers Kit includes graphical user interfaces for creating, packaging, and registering DataBlade modules, and tools for debugging DataBlade modules on Windows™.
While the tools run only on Windows™, you can create DataBlade® modules for both Windows and UNIX™ operating systems for the C, C++, and Java™ languages. The tools you use on each operating system and for each programming language vary.
The DataBlade® Developers Kit includes various resources to help you learn about and develop DataBlade modules.
