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® API Programmer's GuideThe Informix® DataBlade® API Programmer's Guide describes information about the DataBlade® API, the C-language application programming interface (API) provided with HCL Informix®.

Storage characteristics

The storage characteristics tell the database server how to manage a smart large object in an sbspace.

Three groups of information make up the storage characteristics for a smart large object:

Disk-storage information
Attribute information
Open-mode information

You can specify storage characteristics at three points.


When specified	Method of specification
When an sbspace is created	Options of onspaces utility
When a database table is created	Keywords in PUT clause of CREATE TABLE statement
When a smart large object is created	DataBlade® API functions

The following topics describe the three groups of storage characteristics.
