[Eduardo Freni]

Dear Jgnacio, excuse, me for this mail, but i I try to resolve our problems
with dbf files, especially in lan.
I searc from many time (2 years), a good sql translator, for my fivewin and
harbour and xHarbour application.
My customers use, many databases. The databases type are varius.
From My-Sql, Oracle to Sql Server.
I searc a common mode for programs, to access at table for my software.
I found in rdd of OTC, the simple solution.
But the cost for developer, was very hard. The free version, it opened only
five connection.
I test many sql system RDD and library, and, adodb for my application, but
the result is very to cry.
I return at otc mediator.
Yesterday i ask to OTC, of get a special offer for developers, only for
developers, not for customers of developer, who may be pay for to use this
tecnology. I ask with all my heart, why is not possible who i work with
older dbf. It's limit tecnology!.
OTC listened to me, and going beyond every my dream, it distribute the RDD
for my-sql free of money.
In order thanks them of this initiative, sunday prepare a handbook make to
screenshot, for the installation of the client and the serer of OTC, than
connect to my sql.
I try this RDD, is a very robust tecnology, with use command, seek, locate,
replace, ecc ecc. It's very faster plus of dbfcdx, with the same command
xbase.
Of continuation the mail that otc it has sent to xHarbour news group. Very
thanks public to OTC. This is an enormous advantage for all we.
Many thanks to Jacek

ANN: Free unlimited Mediator SQL RDD for MySQL!
--------------------------------------------------------
Dear xBase developers and users!
As announced some time ago, OTC has an exceptional
offer for you. The offer which opens the easy migration
path to SQL for all xHarbour and Harbour developers!
Now we offer full version, unlimited Mediator MySQL RDD
for xHarbour and Harbour for free! Not only for
development and testing but for commercial
installations too!
Mediator SQL RDD is a real RDD driver which allows
your applications to work with SQL databases in exactly
the same way as they work with DBF/NTX and DBF/CDX files.
Consequently, using Mediator, you can quickly adapt your
application to work with SQL databases.
You can download version 4.2.2.1 of Mediator SQL RDD
for MySQL from www.otc.pl. Compared to previous versions,
this version has huge performance optimizations exploiting
new features of MySQL 4.1
Unique Mediator features:
-------------------------
- 100% Clipper/xHarbour-compatible network logic.
All your record, file and exclusive locks work
as expected, being visible even through database
transaction boundaries.
- 100% Clipper/xharbour-compatible transaction logic.
Your changes are immediately visible for other
applications. When required your application can use
extended database transactions as well.
- 100% Clipper/xHarbour-compatible cache logic.
When you perform operations which refresh current record
value (such as GO TOP) you can be sure you get a fresh
copy. No need to rewrite algorithms waiting for changes
introduced to database by other applications.
- 100% Clipper/xHarbour compatible record numbering.
By default, no holes in record numbering are allowed.
Thanks to this feature all RECNO-dependent algorithms
run unchanged. When required, application can also be
switched to perforated record numbering mode.
- Only one database connection required for each
application
- Compatible with both Harbour and xHarbour
- Compatible with free www.xharbour.org version
of xHarbour and with commercial xHarbour as well.
- Compatible with Visual C++, Borland C++ and
Pelles C compilers.
- Dedicated Mediator Delphi components allow for
efficient and easy access to your Mediator-managed
SQL data. More dedicated interfaces under development.
- Enterprise version of Mediator server is also
compatible with 16-bit Clipper applications
- Very efficient and easy to use architecture. Mediator
SQL RDD consists of the client libraries (RDD) which you
link into your application, and Mediator server which
you usually install on the same machine where SQL
database is running. This architecture has many
advantages:
a) No need for ODBC drivers, Oracle OCI or other custom
client software to be installed on the client machines.
All you need to run your application is TCP/IP stack.
b) Very efficient operation. All database operations
are performed locally between Mediator server and SQL
database. Application communicates with Mediator server
using the optimal, specially designed protocol, consuming
as small amount of network resources as possible.
c) Easy monitoring and managing of Mediator server
through local or remote interface. You have access
to all sessions, tables and locks information.
d) Ability to optimize your (x)Harbour/Mediator
applications and installations by analyzing global
profiling information gathered by Mediator server
for each connected session.

Enjoy your way to SQL!
