DBD File
• Record types, device support options, menus, and other configuration options are defined in “database definition files” (.dbd)
• A Database definition file (extension .dbd) containing the specifications for the various record and device types that are going to be referenced by the .db file
• During the IOC booting process, one or more dbd files are loaded

What we will use
• Oracle 9i on Red Hat Linux AS v2.1 - Dell Server
• Apache Web Server
• PHP
– for user interface screens / forms for data input & reading
using web browser
• Perl
– for the uploading of flat files to the RDB & vice versa
• ER Studio
– Logical and Physical design of the EPICS database

K.Vijayan : RDB for Diamond Control Systems
Summary
• A central repository for storing all the EPICS information.
• Unique Record names are maintained
• Hierarchy maintained in the record & field
• Open DB Template files, without alignment change in vdct
• ER Design and user interface screens/forms for data input
are available on the web browser
