Visual DCT is one way to generate database files which is the simplest
one for newcomers to EPICS, but it's not the only way.

Unfortunately we don't have a video of my IOC Database Principles
lecture which is where this topic is covered best, although the slides
are available online so you can look through those — go through the IOC
Applications lectures at http://www.aps.anl.gov/epics/docs/APS2014.php
to learn about creating IOCs. The following lecture IOC Database
Practice also helps by giving examples of techniques commonly used.

There is also a discussion about database programming in the Database
Concepts chapter of the Record Reference manual
  https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14_Concepts
which may fill in a few more details that aren't on my slides.

If you have questions, ask them on this mailing list; there are many
people here who can help.
