  3. 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 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.

  4. 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.

  5. Developers Kit

    The Developers Kit (DBDK) guides contain information about the tools you can use to develop and package modules, which extend the functionality of HCL Informix® databases.

  6. DBDK InfoShelf

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

  7. Developers Kit Tutorial

    The Tutorial is a set of exercises that demonstrate how to create extensions to HCL Informix® and package them as modules by using DBDK. Support for DataBlade Developers Kit (DBDK) is removed starting Informix Server 14.10.xC6.

  8. 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.

    The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
