Aldrich Consulting
Services, Inc.
can solve your data conversion needs with either a custom software application
or you can arrange for a service visit at our US location in Southern New
Jersey.
We can even perform a service at
your facility upon request. You may determine this is the best solution
for your situation if the data cannot leave your facility or the data may
require some manipulation or interpretation on site.
Data Conversion
Different operating systems have
different application software, and each application normally has its own
internal way of saving data. There are some standards such as CSV files for
databases and RTF files for word processing text, however, these are few and far
between and often only save the basic information rather than the full
structure. Other significant areas of incompatibility come from mainframe type
applications that use EBCDIC and packed numbers to keep their data. Data
conversion problems can arise with any interchange system, and although networks
and the Internet can mask many media and format interchange problems, data
incompatibility can still remain.
Simple Data Conversion
Simple data conversion can be
defined as the transferring of files between different operating systems or
backup routines without converting the data.
Examples:
-
Transferring data from Unix
backup tapes to a Windows compatible CD. Unix systems use a line feed and no
carriage return. In this case the line feed would be changed to a carriage
return.
-
Transferring data between
different PC backups
Media Conversion
Back to top
Media conversion is handling
different magnetic or opto-magnetic media. With high-speed communications, it is
now possible to send large files via Internet, and many people have seen this as
the death of tape. But interestingly as communications get faster so do file
sizes that need to be transferred, and with magnetic tape now able to store
100GB of data, it is still in many cases the best way to transfer large volumes
of data. However, there are many types of tape drives, from 4mm DATs to DLT and
IBM LTOs. To interchange data, it is essential to have a compatible drive that
must read the relevant variation of tape that may be provided by the supplier of
data.
Examples:
-
Duplicating a software
suppliers' latest software releases on AS400 to different tapes for customers
who are not using the same tape drive as the software supplier
-
Duplicating sets of master
tapes to create backup copies
-
Duplicating a DDS4 tape onto
DDS1 tapes
Format Conversion
Back to top
Format conversion is required if
each computer has a different operating system. A Unix system often uses
different file systems to a DOS system or an IBM mainframe. The way that files
are stored on tapes can vary enormously due to both operating system and
application. Even on a Windows based PC, tapes could be written with ArcServe,
NT Backup, Legato and many more. As a rule, each tape writing method is
incompatible with others.
Examples:
Magneto-Optical Conversion
Back to top
Optical conversion involves
converting your image files from optical platters including 3.5", 5.25", 12",
14", WORM, Permanent WORM, and Read/Write cartridges to CD, DVD or in some
cases, tape. Our expertise includes processing platters of all sizes including
1.3GB, 2.6GB and 5.2GB platters in “WORM” or “Re-Writable” formats. We will need
to know your system type, application type and the software details that wrote
the disks as well as the same for the converted disks, in order to provide an
accurate conversion quote.
Examples:
-
Direct conversion from
proprietary systems
-
Removal of partial data and
output to CD
-
Panasonic 650MB PD Cartridges
to CD
-
Pioneer WORM Cartridges to DVD
