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.
DataBlade® Developers Kit User's GuideThe HCL OneDB™ DataBlade® Developers Kit Users Guide describes how to use OneDB® DataBlade® Developers Kit (DBDK) tools to develop and package DataBlade® modules.

Project version numbersThe optional version information can be one to four sets of numbers or letters separated by periods: for example, 1.2.3.4. The numbers correspond to the categories major, minor, revision, and release.

Project version numbers

The optional version information can be one to four sets of numbers or letters separated by periods: for example, 1.2.3.4. The numbers correspond to the categories major, minor, revision, and release.

The major and minor numbers can be up to eight characters long; the revision and release numbers can be up to six characters long. Use a consistent version format for all your projects.

The version numbers are combined with the project name as a unique identifier to register the DataBlade® module in the database server and to create the installation directory.

If you change the version numbers or project name, you must regenerate SQL files and installation packaging files in BladeSmith.
