<p class=MsoNormal>This stand-alone sample demonstrates usage of the SDO RDB
Data Access Service in the context of a simple web application.</p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The application starts with a canned database of Companies
and their related Departments.<span style='mso-spacerun:yes'>� </span>Through
the web page interface, a user can:</p>

all Companies in the database</li>
<li class=MsoNormal style='mso-list:l2 level1 lfo1;tab-stops:list .5in'>Display
all Companies and related Departments</li>
<li class=MsoNormal style='mso-list:l2 level1 lfo1;tab-stops:list .5in'>Add a
new Department to a Company</li>
<li class=MsoNormal style='mso-list:l2 level1 lfo1;tab-stops:list .5in'>Delete
all Departments from a Company</li>

the names of Departments in a Company</li>

<h1>Sample Architecture</h1>
<p class=MsoNormal>This is a simple, single-page, web application.<span
style='mso-spacerun:yes'>� </span>The main components of this application are:</p>
<ul style='margin-top:0in' type=disc>
<li class=MsoNormal style='mso-list:l1 level1 lfo3;tab-stops:list .5in'>The
RDB Data Access Service (DAS)</li>
<li class=MsoNormal style='mso-list:l1 level1 lfo3;tab-stops:list .5in'>SDO</li>
<li class=MsoNormal style='mso-list:l1 level1 lfo3;tab-stops:list .5in'><span
class=SpellE>CompanyClient.java</span></li>
<li class=MsoNormal style='mso-list:l1 level1 lfo3;tab-stops:list .5in'><span
class=SpellE>Company.jsp</span></li>
<li class=MsoNormal style='mso-list:l1 level1 lfo3;tab-stops:list .5in'>The
canned <st1:City><st1:place>Derby</st1:place></st1:City> database</li>
</ul>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The <span class=SpellE><b style='mso-bidi-font-weight:normal'>CompanyClient</b></span>
uses the <b style='mso-bidi-font-weight:normal'>DAS</b> directly and provides
high-level services to the <span class=SpellE>jsp</span> such as:</p>
<p class=MsoNormal style='margin-left:.5in'><span class=GramE>public</span>
final List <span class=SpellE>getCompanies</span>()</p>
<p class=MsoNormal>This is a good place to look for how you might use the DAS
in your own application.</p>
<p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p>
<p class=MsoNormal>The <span class=SpellE><b style='mso-bidi-font-weight:normal'>Company.jsp</b></span>
responds to client interaction by invoking services of the <span class=SpellE>CompanyClient</span>.<span
style='mso-spacerun:yes'>� </span>It receives data from the <span class=SpellE>CompanyClient</span>
as SDO data graphs and manipulates <span class=SpellE>SDOs</span> directly to
display data.</p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The canned <st1:City><st1:place><b style='mso-bidi-font-weight:
normal'>Derby</b></st1:place></st1:City><b style='mso-bidi-font-weight:normal'>
database</b> comes preloaded with Companies and related Departments.<span
style='mso-spacerun:yes'>� </span>The database instance is a simple file
folder.</p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The <b style='mso-bidi-font-weight:normal'>DAS</b> accepts
directives (commands) from the <span class=SpellE><b style='mso-bidi-font-weight:
normal'>CompanyClient</b></span><b style='mso-bidi-font-weight:normal'> </b>and
reads and writes to the derby database instance appropriately.<b
style='mso-bidi-font-weight:normal'> <o:p></o:p></b></p>
