<div><p>This example application for distributed relational database use
|
||
|
|
is written in RPG/400<sup>®</sup>, COBOL/400<sup>®</sup>, Java™ and
|
||
|
|
ILE C/400<sup>®</sup> programming
|
||
|
|
languages. This example shows how to use a distributed relational database
|
||
|
|
for functional specification tasks.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Example: Business requirement for distributed relational database</h4><p>The
|
||
|
|
application for the distributed relational database in this example is parts
|
||
|
|
stock management in an automobile dealer or distributor network.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>This program checks the level of stock for each part in the local
|
||
|
|
part stock table. If this is below the re-order point, the program then checks
|
||
|
|
on the central tables to see whether there are any existing orders outstanding
|
||
|
|
and what quantity has been shipped against each order.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>If the net quantity (local stock, plus orders, minus shipments)
|
||
|
|
is still below the re-order point, an order is placed for the part by inserting
|
||
|
|
rows in the appropriate tables on the central server. A report is printed
|
||
|
|
on the local server.</p>

<div class="section"><h4 class="sectiontitle">Technical Notes</h4> <dl><dt class="dlterm">Commitment control</dt>
|
||
|
|
<dd> <p>This program uses the concept of local and remote logical units of
|
||
|
|
work (LUW). Because this program uses remote unit of work, it is necessary
|
||
|
|
to close the current LUW on one server (COMMIT) before beginning a new unit
|
||
|
|
of work on another server.</p>
|
||
|
|
</dd>
|
||
|
|
<dt class="dlterm">Cursor repositioning</dt>
|
||
|
|
<dd> <p>When an LUW is committed and the application connects to another database,
|
||
|
|
all cursors are closed. This application requires the cursor reading the part
|
||
|
|
stock file to be re-opened at the next part number. To achieve this, the cursor
|
||
|
|
is defined to begin where the part number is greater than the current value
|
||
|
|
of part number, and to be ordered by part number. </p>

will not work if there are duplicate rows for the same part number.</div>
