Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ 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®.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.

Regex pattern matchingRegular expressions combine literal characters and metacharaters to define the search and replace criteria. You run the functions from the HCL OneDB™ Regex extension to find matches to strings, replace strings, and split strings into substrings.
Regex RoutinesYou can use regex routines to search for patterns, manipulate text strings, and configure tracing.
