Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ 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 HCL OneDB™.
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 HCL OneDB™ 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 OneDB™ databases.

OneDB Excalibur Text Search DataBlade Module

The OneDB® Excalibur Text Search DataBlade®Module enables you to search your data in ways that are faster and more sophisticated than the keyword matching that SQL provides.

Excalibur text search capabilities include phrase matching, exact and fuzzy searches, compensation for misspelling, and synonym matching. The OneDB Excalibur Text Search DataBlade Module can search any type of text.

The OneDB Excalibur Text Search DataBlade Module uses dynamic links in the Excalibur class library, or text search engine, to perform the text search section of the SELECT statement instead of having the database server perform a traditional search. The text search engine is designed to perform sophisticated and fast text searches. It runs in one of the database server-controlled virtual processes.
