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® Developers KitThe 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.
DataBlade® Module Development OverviewThe HCL Informix® DataBlade® module overview serves as an overview of the HCL Informix® DataBlade® module development process.

DataBlade module components

You can include the following objects in the DataBlade® module project you create with the DataBlade Developers Kit:

Aggregates: Perform user-defined computations on data
Data types: Characterize data to the database server (either built-in data types or new data types)
Routines: Operate on or return data
Casts: Convert data from one type to another
Interfaces: Create dependencies between DataBlade modules
Errors: Create messages raised by user-defined routines that appear as standard database server messages
Unit tests: Test your database objects during the coding and debugging cycle
Functional tests: Validate your completed DataBlade module routines
Imported SQL files: Include custom SQL statements to create tables, user-defined access methods, and other database objects in your DataBlade module
Imported client files: Include client components, such as query tools and ActiveX value objects, in your DataBlade module package

The DataBlade Developers Kit generates the SQL for each of the objects that you define or include.

Important : Not all database objects and options described in this section are available with all versions of HCL Informix®. For more information, see the Informix DataBlade Developers Kit User's Guide.
