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 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.

      - BladePack
        BladePack creates installation packages for DataBlade® modules and other software products.
        Prerequisite tasks
        BladePack overview
        BladePack produces installation packages for installing products on UNIX™ and Microsoft™ Windows™ operating systems. BladePack can create a simple directory tree containing files to be installed or an installation that includes an interactive user interface.
        Packaging for UNIX™ installations
        To package your DataBlade® module, you add content to a BladePack project, assign components, customize the installation procedure, and build the package.
        Packaging for InstallShield 3.1 installations
        To package your DataBlade® module, you add content to a BladePack project, assign components, customize the installation procedure, and build the package.
        Building an installation package with BladePack
        Establish content
        Manage components
        BladePack allows you to organize your product installation package into three layers: component, subcomponent, and shared component. To see the component hierarchy for your product, click the Components tab in the project view.
        Creating a component
        Creating a subcomponent
        Creating and copying a shared component
        Component properties
        Assigning items to components
        You must assign every item on the Files/Directories and Customization tabs to a component, subcomponent, or shared component. If you try to build the project with unassigned items, the build fails and you receive an error message telling you which item is not assigned to a component.
        Customize the installation
        Build the installation
        When the content and organization of your installation package are complete, build and test it.
        Create distribution media
        To ensure that customers can install DataBlade® modules and other HCL Informix® products by using common instructions, the product you distribute must conform to the HCL Informix DataBlade module installation standard. BladePack creates an interactive installation that ensures a consistent user interface.
        Packaging for InstallShield 5.1 installations

Manage components

BladePack allows you to organize your product installation package into three layers: component, subcomponent, and shared component. To see the component hierarchy for your product, click the Components tab in the project view.

Organizing an installation package into a component structure allows you to define Typical, Compact, and Custom installations. You specify whether each component or subcomponent is included in the Typical and Compact installations, and whether it is initially selected when users choose the Custom installation.

Use a shared component for those portions of your product that are shared by more than one component. A shared component is always installed with the subcomponent with which it is associated.

During a Custom installation, users can choose to install any components or subcomponents. When you mark a component Custom, the component is initially selected. The user can choose to include or exclude any components, except shared components, from the installation.

In most cases, the component level is sufficient to create Typical, Compact, and Custom installation options. For example, suppose you have created the following components (and no subcomponents) in your installation package and marked them as shown:

DataBlade® module. Typical, Compact, Custom.
Help. Typical.
Examples. Typical.
Debugging Support. Custom.

In this scheme, users install the DataBlade® module, help files, and examples if they choose the Typical installation. If they choose the Compact installation, they install the DataBlade® module only. If they choose the Custom installation, the DataBlade® module and debugging support are preselected. They can choose to add help and examples.
