XStudio 3160

Changing Data

In most cases modification of data, whether it occurs within XStudio or is a result of a client utility

application making changes, is transparent and automatically handled by XStudio. If a Task is updated,

for instance, the next time the Task is used in an Action, the new information is used regardless of

whether the change was made within XStudio or made with a utility application connecting remotely.

However, if a remote utility application is re-importing the music library, for instance, and XStudio

needs to retrieve song title and artist information, the cart may not be found if the import is in progress

at the time of the lookup.

5.2.4 Inventory Manager Database

The XStudio Inventory Manager (InvMgr) Database is separate from the XStudio application

database. Current audio inventory information is stored in this database and information is

automatically updated as the on-disk inventory of available audio files changes.

5.2.4.1 InvMgr Files Location

As a default, XStudio Inventory Database files are located in a folder immediately under the XStudio

installation folder. The folder is named "InvData" and is automatically created when XStudio is

launched for the very first time.

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

tables and support files that comprise the database.

Inventory database files, referred to as the XStudio Inventory 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.

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

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

behave unpredictably.

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

option in XStudio preferences.

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

backup purposes.

5.2.4.2 InvMgr Database Tables

The XStudio inventory manager 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.
