External modules can used to extend the functionality of ElevateDB to external code in the form of DLLs. The functionality that can be extended via external modules includes:


Creating External Modules

---

External modules can be created in any language that can generate a DLL (Dynamic Link Library) with a C-style calling convention, which is the standard calling convention for DLLs under Windows. In addition, ElevateDB provides template projects for the various types of external modules in every specific compiler or IDE that it supports. Please see your product-specific manual for more information.


Installing External Modules

---

In order to use an external module in ElevateDB, you must make sure that the module is registered in the current configuration file by using the CREATE MODULE statement. You can verify that this is done by using the following SELECT statement on the special system-defined Configuration Database:

SELECT * FROM Modules

If the rows returned from the above query include the module that you wish to use with ElevateDB, then external module has been registered successfully in the configuration file. Please see the Architecture topic for more information on the configuration file.

Once an external module has been registered correctly, it can then be used with ElevateDB with procedures and functions, text indexing, and/or database migration.
