<p class="h1">Data Abstract Sample Server</p>
|
|
|
|
<p>
|
|
This application is one of available samples that can act as a server for the client applications in the PCTrade Sample Suite.
|
|
It provides almost all information about the underlying activities of Data Abstract.
|
|
</p>
|
|
<p>
|
|
While "real life" middle-tier servers are usually black boxes that run without any user interface as Windows Services or Daemons,
|
|
this sample - for illustration purposes - takes the opposite approach and for each request made from a client provides
|
|
textual descriptions of the processing that the Data Abstract library did underneath the hood to service the request.
|
|
Thus, it provides a great opportunity to learn how Data Abstract works.
|
|
</p>
|
|
<p><b><font color="red">NOTICE</font></b><br/>
|
|
The Data Abstract for Delphi PCTrade samples suite ships with a precompiled sample server. The executable file along with some
|
|
support files necessary can be found under \Bin subdirectory of the sample directory, as well as in the Windows Start Menu.<br/>
|
|
The precomipled server executable was built using AnyDAC data access suite, available as separate product, to provide more data access options.
|
|
Please visit <a href="http://www.anydac.com">http://www.anydac.com</a> for more information.
|
|
In addition to AnyDAC, the server uses dbExpress components for data access to Firebird.<br/>
|
|
When you compile the sample server yourself, the executable file produced will also be placed into \Bin subdirectory.
|
|
The executable file should be located there for the server to work correctly.<br/>
|
|
<b>WARNING:</b> if you are going to build the server with Delphi version prior to 2010 you must rename or delete the
|
|
dbxdrivers.ini file from the \Bin directory and have a properly configured dbExpress suite installed.
|
|
</p>
|
|
|
|
<p>
|
|
<b>NOTICE:</b><br/>
|
|
Unfortunately, our preferred out-of-the-box databases for this sample, SQLite and Firebird,
|
|
have problems with accessing Unicode fields in <b>Delphi 7</b>. We are trying to resolve
|
|
this for a future release, but until then, please set up a Microsoft SQL Server or MSDE
|
|
test database with the provided .backup file, to run these samples. You can also use the precompiled
|
|
server executable in this case.
|
|
This only affects <b>Delphi 7</b>, and only when you manually rebuild the server. We apologize for the inconvenience.
|
|
</p>
|
|
|
|
<p class="h2">Examine the sample</p>
|
|
<p>
|
|
Majority of the server code was written to support logging of Data Abstract internal activity or other things rarely used in real life.
|
|
Such code is not related to any sample in particular.
|
|
There are several exclusions, please read corresponding samples descriptions for required server code references.
|
|

|
|
<p class="h2">Getting started</p>
|
|
<ul>
|
|
<li>Launch the Sample Server executable.</li>
|
|
<li>Check if the default database connection was successfully established (examine the log window).</li>
|
|
<li>
|
|
You may change the database server connects to. Click desired connection description in the list box
|
|
and examine the log window to find out if connection was established successfully.
|
|
</li>
|
|
<li>Run the samples supplied and examine the log output to see Data Abstract internal data processing details.</li>
|
|
<li>Use Clear Log button to get rid of text written to the log window.</li>
|
|
</ul>
