5.2 Database Reference

The XStudio Database is a collection of files called "tables" and is used to store components of

automation operations, including tasks, actions, resources used by tasks and scheduled events. There

are also tables for song title and artist information (music database) and broadcast log historical

information.

A second database, known as the XStudio Inventory Database, is also used. This database is a

collection of tables used to store current audio inventory information.

5.2.1 Database Files Location

As a default, XStudio database files are located in a folder immediately under the XStudio installation

folder. The folder is named "Data" and is automatically created when XStudio is launched for the very

first time.

A number of files are created in the Data folder when XStudio is first launched; these consist of the

tables and support files that comprise the database.

Database files, referred to as the XStudio Database, are owned exclusively by XStudio as a default;

when XStudio is running, no other application is allowed access to these files. Any attempts to open,

copy or delete these files will be denied by the operating system, as they are already opened

exclusively by XStudio.

You can make the data available to other applications by setting the Allow Remote Administration

option in XStudio preferences. When Remote Administration is enabled, applications like XStudio

Administration can be used to remotely update the database.

Files in the Data folder should never be deleted or otherwise modified, as loss

of XStudio functionality or corrupted data will result, causing XStudio to behave

unpredictably.

When XStudio is not running, the database files can be copied, if desired, for archiving, cloning or

backup purposes.

5.2.2 Database Tables

The XStudio database is a collection of tables, stored on-disk as one file per table. This section

documents tables that are a part of the database, including technical information on fields contained in

each table, their type and usage.

All tables are binary data files having a file extension of "NX1". Files are created and maintained using

NexusDB, created by Nexus Database Systems Pty Ltd. NexusDB is a fast, flexible, reliable database

engine embedded in XStudio and supplied royalty-free to the end-user. There's also the option to run

NexusDB as a stand-alone server, implementing true multi-user, client/server database operations.

5.2.2.1 Actions Table

The Actions table contains information about all defined Actions. Its on-disk name is: Actions.nx1

Actions Table Field Definitions

The fields contained in the Actions table, including field type and size (if applicable).
