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.

  - Database Extensions User's Guide
    The Informix® Database Extensions User's Guide explains how to use the database extensions that come with HCL Informix: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, and SQL packages.
    - Large object management
      The Large Object Locator extension enables you to create a single consistent interface to large objects. It extends the concept of large objects to include data stored outside the database.
    - MQ Messaging
      WebSphere® MQ (WMQ) messaging products provide an infrastructure for distributed, asynchronous communication of data in a distributed, heterogeneous environment. The WMQ message queue allows you to easily exchange information across platforms.
    - Binary data types
      The binary18 and binaryvar data types allow you to store binary-encoded strings, which can be indexed for quick retrieval.
      - Binary data types overview
        To implement binary data types, the Scheduler must be running and the database must conform to requirements. The binary18 and binaryvar data types have certain restrictions due to the nature of binary data.

        The bdttrace() function
        The LENGTH() function
        The OCTET_LENGTH() function
    - Basic Text Search
      You can perform basic text searching for words and phrases in a document repository stored in a column of a table.
    - Hierarchical data type
      The node data type helps to resolve a difficult relational database problem–transitive closure.
    - SQL Packages Extension
      The SQL packages extension provides SPL routines that you can use in an application that is compatible with database servers other than Informix®.
    - Regex pattern matching
      Regular expressions combine literal characters and metacharaters to define the search and replace criteria. You run the functions from the Informix® Regex extension to find matches to strings, replace strings, and split strings into substrings.
  - Performing XML Publishing
    The Informix® XML User's Guide includes information about using built-in functions for XML publishing with Informix.
  - Spatiotemporal Search for Moving Objects User's Guide
    The describes how to program applications to search data from moving objects in HCL Informix® databases using the spatiotemporal search extension.
  - TimeSeries Data User's Guide
    The Informix® TimeSeries Data User's Guide contains information to assist you in using the TimeSeries extension with HCL Informix.
  - Web DataBlade Module
    Use the Web DataBlade® module to create web applications that incorporate data that is retrieved dynamically from the HCL Informix® database.
- 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.

The bdtrelease() function

The bdtrelease() function provides the version number of the binary data types.
