Siebel 8.0 Essentials

Module 14: Siebel Application Architecture


Module Objectives

• To describe the major types of object definitions• To describe the relationships between them


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 components– Configuration files and the Siebel Gateway Name Server that specify 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 render the UI in the user’s– A Siebel Repository File (SRF) containing compiled object definitions


The Siebel Application Architecture…

• Object definitions are created, modified, and stored in special tables in the database and compiled to the SRF


Siebel Repository File (SRF)• Contains compiled object definitions that specify:

– Presentation of data– Business logic– Physical table storage


Object Definitions

• Provide the foundation for application execution• Are grouped in three layers with different purposes• Refer to definitions in the next lower layer


Data Layer

• Data layer object definitions specify the logical structure of the physical database

– Definitions are metadata, not data• In the Data layer, there are two principal data object definitions:

– Table definitions– Column definitions

S_SRV_REQ

SR_NUM INS_ PRODUCT SR_AREA

Table

Column


Business Layer

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

– Business component– Business object

Business Object

Business Component


Business Component (BC)

• Represents one fundamental business entity in the enterprise– For example: Service Request, Contact, Activity

• Represents a logical grouping of data from one or more tables• Refers to a base table• Consists of multiple fields that characterize the business component

– Many fields within the business component reference columns in the base table

Service Request

SR # Type Area

S_SRV_REQ

SR_NUM INS_ PRODUCT SR_AREA

Business Component

Base Table

Field

Column


Business Component…

• Can include data from additional related tables– Some fields map to columns in these related tables

Service Request

SR # Account Owner

SR_NUM NAME LOGIN

S_SRV_REQ S_ORG_EXT Owner-S_USER

Business Component

Field

Column

Base Table

Additional Table


Business Object (BO)

• Is a collection of related Business components (BCs)• Represents a major functional area of the enterprise• For example, order management• Contains specific details about the relationships between BCs• One BC is the master or driving BC• Organizes related business components

Service Request

Service Request

Action Account

Business Object (BO)

Parent BC provides focus for BO

Business Component(BC)


Comparing BCs and BOs

• Business Objects provide focus to views and organize BCs• Business Components provide data to applets and control data manipulation in tables


UI Object Definitions

• There are five principal UI objects within the user interface

1. Application

2. Screen

3. View

5. List Column or Control

4. Applet


Control and List Column Object Definitions

• Provide the ability to display and manipulate data

This column displays data in a columnar list

This Control displays data in

a field via a form


Applet Object Definition

• A section of a view, such as a list or form• References one business component whose data can be viewed and edited through the list or form• Consists of list column or textbox control object definitions• Refer to fields in the applet-referenced business component• Specify how the data for the fields is displayed in the list or form

Service Request

SR # Last Name Owner


View Object Definition

• Specifies a view in a Siebel application• Contains multiple applet object definitions • Service Request – My Service Request View

BO

BC

View references one BO

Applet references one BC


Screen Object Definition• Specifies a screen in a Siebel application

– Is associated with a major functional area of the enterprise• Contains multiple view object definitions that usually refer to the same business object

– Administration screens are an exception

Views in Screen

Screens


Application Object Definition

• Specifies a particular collection of screens available in a Siebel application


Configuring Siebel Applications

• Is accomplished by using:– An HTML editor to modify template and other physical UI files– Siebel Tools to modify object definitions


Module Highlights• Siebel architecture uses object definitions that specify application behavior• Use Siebel Tools to:

– Create, store, and modify object definitions in the database– Compile object definitions into the SRF for more efficient run-time

access• 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


Lab

• In the lab you will:– Examine how UI layer object definitions reference business layer

object definitions
