circulation locations, and policies as well as setting up location calendars. Internals Voyager uses an Oracle database and the Apache Tomcat web server. Reporting functionality utilizes Perl scripts. As stated above, for its modules it uses custom Microsoft Windows programs. The only programming API for Voyager is the BatchCat.dll which provides most of the same functionality as the Voyager Cataloging client. The Voyager web server also provides a limited number of XML services and web APIs for integration purposes. The only window into Voyager for library staff is via the exposed tables of the Voyager database. The Access Reports frontend to this database provides dozens of pre-built SQL queries written by Endeavor to help library staff create reports. It is also possible to write software that connects directly to the database and reads the tables from there. However none of the indexing that makes Web Voyager so fast is exposed for the ordinary programmer. The tables of Voyager are shorthand versions of the MARC bibliographic records. The actual MARC records are stored as BLOBs but certain portions of the MARC record are extracted and stored in tables. For example, BIB_TEXT.TITLE is, naturally, the MARC Bibliographic Record field that holds the Title. The Bibliographic Records are stored in tables named BIB*. The Holdings records are in tables named MFHD* (Marc Format for Holdings Data). The Authority Records are in AUTH. Voyager adds its own record, called the 'Item Record'. This stores the barcode, 'media type', location, and other information. The result of this is that there can be some redundant pieces of information in the database, particularly 'location' and 'media type'. References External links Ex Libris Group Library automation
