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® API Programmer's GuideThe Informix® DataBlade® API Programmer's Guide describes information about the DataBlade® API, the C-language application programming interface (API) provided with HCL Informix®.
Create user-defined routines
Develop a user-defined routineA C user-defined routine (UDR) is a UDR that is written in the C language and uses the server-side implementation of the DataBlade® API to communicate with the database server. C UDRs (functions and procedures) are implemented as C-language functions. DataBlade® modules often include C UDRs that are made available for use by registering them in the database.
Designing a UDRThis section provides the following design considerations for the development of a C UDR: development tools, uses of a UDR, portability, and insert and update operations.
Development toolsThe creation of a C UDR involves the production of source code, header files, SQL statements, and many other files. These topics describes how to generate the code for C UDRs yourself, using the DataBlade® API and the basic tools available with an operating system.

A DataBlade module is a package of software that extends the functionality of the database server. It can include the following objects:

New or extended data types
UDRs
Error messages
Functional tests
Interfaces to other DataBlade modules
Packaging and installation scripts
