Administrator Emeritus

There are many people here who come from an Electrical/Electronics or related dicipline, including all three of the Admins, so for a start you should not feel that this is anything of a disadvantage in getting where you want to go. Any knowledge gained in either area will be useful, maybe not directly, but will stand to you in the long term.

As for the specifics of this case, cbkihong has already indicated that most modern websites are in fact web "applications" sitting in front of databases of varying size, from the small site where someone has their own blog and nothing else, to huge corporate sites to online shops. In order to be an effective web designer you will need to know how to interact efficiently with databases in order to develop effective websites, so my advice would be to take the database course.

CTL_CYRUSDB(8)						      System Manager's Manual						    CTL_CYRUSDB(8)

NAME

       ctl_cyrusdb - perform operations common to all Cyrus databases

SYNOPSIS

       ctl_cyrusdb [ -C config-file ] -r [ -x ]
       ctl_cyrusdb [ -C config-file ] -c

DESCRIPTION

       Ctl_cyrusdb is used to perform various administrative operations on the Cyrus databases.

       Ctl_cyrusdb  reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.  The configdirectory option is
       used to determine the default location of the Cyrus databases.

OPTIONS

       -C config-file
	      Read configuration options from config-file.

       -r     Recover the databases after an application or system failure.  Also performs database cleanup  like  removing  mailbox  reservations
	      (and any associated mailbox files).

	      All  mailbox  files  are	also checked to make sure the file format matches the configured database type in imapd.conf.  If not, the
	      file is automatically converted using the same logic as cvt_cyrusdb.

       -x     Used with -r to recover the database only.  (Prevents database cleanup).

       -c     Checkpoint and archive the databases.  Changes to the database which are part of committed transactions are written to disk.   Also,
	      a hot backup of the databases is made and inactive log files are removed.

FILES

       /etc/imapd.conf
