Columbia, MO Jan 5, 1999 –FairCom Corporation announced the latest
release of the c-tree Plus V6.8A file handler for the Macintosh OS
8.5, at Macworld Expo99. This new release of FairComs C ISAM
database API offers flexible file limits, and enhanced file
mirroring. Other major features of this release include an enhanced
data history function, which makes it possible to access the audit
logs of transaction controlled files, and an improved portable
multi-threaded client API. When used with the FairCom Server, this
version of c-tree Plus also offers file encryption.
The ability to encrypt data and index files as well as transaction
log files has also been added to the FairCom Server. “This technology
provides the extra level of confidentiality to an application’s
data.” explains FairCom Europe Manager, Franco Cortinovis. “We’re
seeing an increasing number of requests for this in the past year,
and beta testing has performed flawlessy.”
Files that are encrypted using the FairCom Server’s encryption
algorithm can only be decrypted by the FairCom Server. This feature
prevents standalone applications from gaining access to sensitive
data. In addition, the FairCom Server SDK provides an additional
level of security by allowing developers to customize the encryption
process so that only the server that has encrypted the
data can access it. FairCom has also just released a Mac Server SDK.
FairCom Macintosh Servers also allow simlutaneous communication with
TCP/IP and AppleTalk protocols, and offer support for multiple
communication protocols, like ADSP; SPX and NetBIOS.
c-tree Plus application developers are no longer required to know
before initializing c-tree how many data and index files their c-tree
open. c-tree Plus now includes FairCom’s “flexible file limit” logic,
which allocates file control blocks as needed. This dynamic
allocation of file control blocks requires less memory than the
static method previously used and allows applications to exceed the
maximum number of open files that was specified at initialization
The enhanced file mirroring included in this release offers several significant
features. c-tree Plus V6.8 now has automatic copy of file mirrors,
which will permit a rebuild to continue if a mirrored copy fails.
Additional mirror enhancements include: automatic updates of indexed
mirrored files, automatic correction of mirrored index deleted or
recreated files, and others.
The new multi-threaded API offers significant performance gains, due
to the benefits of concurrent and/or parallel thread execution.
Concurrent thread execution means two or more threads are in process
at the same time.” explains Winston Atkisson, Senior Engineer at
FairCom. Multi-threaded benefits may be implemented by using
FairCom’s efficient, system-independent, multi-threaded API, for both
the multi-user stand-alone model and the multi-threaded client/server
model. Because this API handles all system-specific threading issues
that arise when moving between operating systems (even those not
supporting native threading) it saves a lot of work, and insures the
application’s portability.” Atkisson adds.
The enhanced transaction history function allows for the accessing of the audit
logs of transaction controlled files. This enables the programmer to
scrutinize the changes performed on each unit of information at a
level: a particular record position within a specific file; a
particular key value of a specific index; and/or updates to a
particular file, including updates by a particular user or
workstation ID. One such use of this technology
has been to track the changes made to a manufactured device as it
proceeds through an automated fabrication factory. The exact
individual history of each manufactured device can be determined from
the transaction log files.
This latest version of c-tree Plus and the FairCom Server include new
support for the following platforms: FreeBSD Unix, SCO UnixWare, SGI
IRIX and AIX V4.3.
FairCom created Access Manager for Digital Research in 1979 and
released its first true application development tool, the original
c-tree file handler, that
same year. Today c-tree Plus is running in over 100 CPU/OS environments in more
than 98 countries worldwide. FairCom technology is utilized by such
noted organizations as: McGraw-Hill, Federal Aviation Administration
and Federal Express. Corporations like Computer Associates and Sharp
Corporation have embedded FairComs c-tree Plus within vertical
market products and licensed its
Server technology for OEM uses. Mac OS X “Rhapsody” is currently
c-tree Plus V6.8A is priced at $895 with full C source code, no
royalties, 26+ free development Servers, and Development ODBC
Drivers. Full support for over 25 platform from Windows to Mac is
included with each package. For more information on any of these
