DISCLAIMER FOR DATA SOLD
Ordering Procedures:
Each purchaser must appropriately
complete the Dallas Central Appraisal District (DCAD) Data Information Available
form and submit the form and payment in full
to DCAD. DCAD claims no responsibility for ordering of data. It is the responsibility
of the purchaser to understand the data files being purchased. Each requestor
will be provided technical descriptions of data sold to the public. DCAD
is not responsible for recreating data files free of charge due to misordering
of data.
Tape Specifications:
All cartridge tapes are created
on an IBM 3480 cartridge tape drive which is attached to an IBM 9672-R21
mainframe. This is a non-IDRC 3480 drive and creates cartridges in EBCDIC
format with standard label only. The cartridge drive has error recovery
features including the ability to write erase gaps and skip over them when
reading.
All data sold is produced on
magnetic cartridge tapes that have been verified to be readable before they
leave DCAD. It is created in an environmentally controlled atmosphere with
the cartridge drives calibrated to be within published IBM tolerances.
Cartridge damage can occur if
cartridges are exposed to the elements, such as moisture and temperature.
The cartridge media should be stabilized for at least 10 hours prior to
use to minimize problems. Cartridge drive maintenance and cleanliness have
a direct bearing on how well a cartridge can be processed. DCAD is not responsible
for recreating data free of charge due to damage caused after the cartridges
leave DCAD.
CD-ROM Specifications:
Each CD-ROM includes Alchemy
software to read and retrieve the data. Per our CD-ROM vendor, Alchemy must
be used as a single user license and installed on only one PC. Additional
users require a site license.
Technical Support:
Technical support is only available
Monday thru Thursday, 0730-1730. This support is only available to customers
who have actually purchased the data directly from DCAD and will terminate
14 days after cartridge tapes and CD-ROMs are signed for.
