<div><p>The examples in this topic collection are based on
|
|||
|
|
representative application programs that might be used for processing data
|
|||
|
|
both on the local <span class="keyword">iSeries™ server</span> and
|
|||
|
|
on one or more remote servers.</p>
|
|||
|
|
<div class="section"><p>The first example is a simple inquiry application, and the second
|
|||
|
|
example is an order entry application. The third example accesses multiple
|
|||
|
|
files on multiple <span class="keyword">iSeries server</span>s.
|
|||
|
|
The fourth example accesses multiple <span class="keyword">iSeries server</span>s
|
|||
|
|
and a <span class="keyword">System/36™</span>.</p>
|

|
|
</div>
|

|
|
<div class="section"><p>The coding for each of these examples and tasks has one or two
|
|||
|
|
parts:</p>
|
|||
|
|
<ul><li>Coding, shown in pseudocode form, not related to DDM but used to build
|
|||
|
|
the programming environment. The examples show you the task steps needed,
|
|||
|
|
independent of the language you use for your applications. You can write or
|
|||
|
|
adapt your programs in your language with the necessary coding to perform
|
|||
|
|
these or similar tasks.</li>
|
|||
|
|
<li>Coding, mostly done in CL, related to communicating with the other servers
|
|||
|
|
using DDM in the network.</li>
|
|||
|
|
</ul>
|
|||

<li class="ulchildlink"><strong><a href="rbae5commsetup.htm">Communications setup for DDM examples and tasks</a></strong><br />

These topics describe the network in which DDM is used for these task examples.</li>

|
|
<li class="ulchildlink"><strong><a href="rbae5apaex1.htm">DDM example 1: Simple inquiry application</a></strong><br />
|
|||
|
|
This first example shows how multiple locations in a customer's business might be processing the same inquiry application on their own servers, using their own primary files. Without DDM, the two locations shown here (Chicago and Toronto) have their own primary file (CUSTMAST), both with different and duplicate levels of information.</li>
|
|||
|
|
<li class="ulchildlink"><strong><a href="rbae5apaex2.htm">DDM example 2: ORDERENT application</a></strong><br />
|
|||
|
|
This second example shows how multiple locations in a customer's business can process the same order entry application using DDM.</li>
|
|||
|
|
<li class="ulchildlink"><strong><a href="rbae5apaex3.htm">DDM example 3: Access multiple iSeries files</a></strong><br />
|
|||
|
|
Using the same communications environment as in the previous examples,
|
|||
|
|
this example is used to ask inventory questions of identically named files
|
|||
|
|
on the two remote <span class="keyword">iSeries server</span>s
|
|||
|
|
and the remote <span class="keyword">System/38™</span>.</li>
|
|||
|
|
<li class="ulchildlink"><strong><a href="rbae5apaex4.htm">DDM example 4: Access a file on System/36</a></strong><br />
|
|||
|
|
This topic shows how the pseudocode program for the previous task
|
|||
|
|
can be changed so a MASTER file on the <span class="keyword">System/36</span> in
|
|||
|
|
Dallas can be accessed in the same way as the MASTER files on the <span class="keyword">iSeries server</span>s and <span class="keyword">System/38™</span> in
|

Example 3.</li>
