Module Objectives

After completing this module you should be able to:

Describe the major types of object definitionsDescribe the relationships between them

Why you need to know:Enables you to explore an existing application effectivelyProvides the foundation you need to configure the objectdefinitions that form the basis of an application

The Siebel Application Architecture

Recall that the Siebel Application consists of:

An execution engine that provides the application behavior The Siebel Server(s); more specifically, their componentsConfiguration files and the Siebel Gateway Name Server thatspecify operating parameters for the execution engine

Most configuration parameters are stored in the Gateway Name Server

A relational database that stores user data A set of physical User Interface (UI) files that specify how to renderthe UI in the users

A Siebel Repository File (SRF) containing compiled objectdefinitions

The Siebel Application Architecture Continued

Object definitions are created, modified, and stored in special

tables in the database and compiled to the SRF

Data Layer

Data layer object definitions specify the logical structure of thephysical database

Definitions are metadata, not data

In the Data layer, there are two principal data object definitions:Table definitionsColumn definitions

ORDER_NUM

S_ORDER

DISCNT_PERCENT STATUS_CD

Columns

Table



Business Layer

Business object definitions specify the business logic for theapplicationIn the Business layer, there are two principal objects:

Business componentBusiness object

Businessobject

Businesscomponent



Business Component (BC)

Represents one fundamental business entity in the enterprise

For example: Service Request, Contact, ActivityRepresents a logical grouping of data from one or more tablesRefers to a base tableConsists of multiple fields that characterize the businesscomponent

Many fields within the business component reference columns inthe base table

Order Number Discount Status

ORDER_NUM

Order Entry - Orders

Business Object (BO)

Is a collection of related Business components (BCs)

Represents a major functional area of the enterpriseFor example, order management

Contains specific details about the relationships between BCsOne BC is the master or driving BCOrganizes related business components

Comparing Business Components and Business Objects

Business Objects provide focus to views and organize BCs

Business Components provide data to applets and control datamanipulation in tables

UI Object Definitions

There are five principal UI objects within the user interface

3. View

4. Applet

1. Application

2. Screen

5. ListColumn or

Control



Control and List Column Object Definitions

Provide the ability to display and manipulate data

This columndisplays data in acolumnar list

This controldisplays data

in a field viaa form



Applet Object Definition

A section of a view, such as a list or form

References one business component whose data can beviewed and edited through the list or formConsists of list column or textbox control object definitions

Refer to fields in the applet-referenced business componentSpecify how the data for the fields is displayed in the list or form

Order Number Account Opportunity

Order Entry - Orders



View Object Definition

Specifies a view in a Siebel application

Contains multiple applet object definitions

Order Entry

- Orders

Screen Object Definition

Specifies a screen in a Siebel application

Is associated with a major functional area of the enterpriseContains multiple view object definitions that usually refer to thesame business object

Administration screens are an exception

Screens

Same screenViews in

that screen



Application Object Definition

Specifies a particular collection of screens available in a Siebelapplication

Application



Configuring Siebel Applications

Is accomplished by using:

An HTML editor to modify template and other physical UI filesSiebel Tools to modify object definitions

Physical UI Files

UI Object Definitions

Business Object Definitions

Data Object Definitions

Conf igurable Layers

Use an HTML editor tomodify template

Use Siebel Tools to modifyobject definitions

Module Highlights

Siebel architecture uses object definitions that specifyapplication behavior Use Siebel Tools to:

Create, store, and modify object definitions in the databaseCompile object definitions into the SRF for more efficient run-timeaccess

Object definitions are grouped into three layers:UI Layer

Includes applications, screens, views, applets and list columns/controls

Business Layer Includes business objects and business components

Data Layer Includes tables and columns
