However, all schema objects are programmatically accessible at run time through the schema object model, with the <a href="C1.Data.2~C1.Data.SchemaObjects.Schema.html">C1.Data.SchemaObjects.Schema</a> class being the root of that object model. Using this object model, it is possible to modify the schema or even define it from scratch at run time, using the CreateSchema event. To access and modify the Schema object, use the <a href="C1.Data.2~C1.Data.C1SchemaDef~Schema.html">Schema</a> property. In a <span>3-Tier Application</span>, this event is called both for the client and server instances of the data library. If you modify schema in this event, you may need to know whether it occurs on the client or on the server, for example, to modify database connections differently depending on where the event occurs. This information can be obtained from the RunsAt property.</div> <a name="exampleBookmark"></a> <a name="seealsobookmark"></a> <div class="SectionHeading" id="seealsoSectionHeading"><span class="SectionHeadingIcon"><!-- --></span><span class="SectionHeadingText">See Also</span></div><div id="seealsoSectionContent" class="SectionContent"><h4 class="subHeading">Reference</h4><p><a href="C1.Data.2~C1.Data.C1SchemaDef.html">C1SchemaDef Class</a> <br><a href="C1.Data.2~C1.Data.C1SchemaDef_members.html">C1SchemaDef Members</a> <br><strong>Schema Objects</strong> </p> </div> <div id="FooterContent"> <p> </p><p> </p><hr style="height: 1px"><p>Copyright (c) <script type="text/javascript"> var theDate=new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
