  2. 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.

  3. Creating extensions

    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.

  4. DataBlade® Developers Kit

    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.

  5. DBDK InfoShelf

    The DataBlade® Developers Kit InfoShelf is designed to help you work with BladeSmith.

  6. DataBlade® Developers Kit Tutorial

    The 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.

  7. Tutorial exercise 4: Creating opaque data types

    This exercise demonstrates how to create opaque data types, their support routines, and user-defined routines that operate on them. This exercise has 11 steps. It takes approximately one hour to complete.
