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 concepts
What are DataBlade® modules?A DataBlade module is a software package that extends the functionality of HCL Informix®.
Why extend your Informix® database server?The primary advantages of using the extensibility of HCL Informix® over using traditional relational databases and applications are better performance, simpler applications, transaction control, and scalability.
Transaction control

Transaction control

DataBlade® modules become part of the database. Therefore, all operations carried out by DataBlade module routines are supported by database services, such as backup, rollback, and recovery. You can safely store your data, which you formerly stored in files, in the database by using smart large objects.
