2 PeopleSoft Internet Architecture Any web enabled device can access Peoplesoft Servers can be on one or more machines No code written on the client Provides dynamic hyperlinks, like any webpage

3 Benefits of Internet Architecture Easy Access Platform Independence Look and Feel Low Bandwidth Access Maintenance/Deployment Cost effective

4 Metadata Driven Architecture Peoplesoft Application Designer: Allows you to create Peoplesoft Applications: fields, records, pages, components. When you define a page for example, this definition is stored in the metadata file. Metadata: data about data When executed, looks for latest version

5 Metadata Architecture

6 Development Environment Developers (those creating the Peoplesoft pages) and Administrator (those maintaining the system) Do not need Internet access Use more powerful machines Use a Two-Tier connection End users use Three-tier connection

7 Development Environment

8 PeopleSoft Internet Architecture Four components Internet access device Web Server Application Server Database Server Similar to other others: ex. Amazon

9 PeopleSoft Internet Architecture

10 Architecture issues No software to install on the clients No plugins necessary Simple, open architecture

11 Web Server Purpose Relay data from Browser to Application Server Handle encryption Serve up the image Connection between Browser and Application Server

12 Web Server

13 Application Server Where the PeopleSoft logic resides Brain of the Internet application Generates the HTML which shows up in the browser Two pieces Tuxedo: handles communication between client and Peoplesoft Jolt: connections to Java applets

14 Application Server

15 Database Server

16 Database server Contains 3 sets of tables (files) System Catalog Tables: store indexes and physical characteristics of tables PeopleTools Tables: store object- related data pertaining to the online processing of the system and the activities that occur during import Supplied by the system

22 Relational Databases Files called tables in PeopleSoft Key fields: uniquely identify a row (record) Indexes of keys make data storage and retrieval more efficient

23 PeopleSoft Record

24 PeopleSoft Data Models These are set up by PeopleSoft One model for each function Samples next page


26 Data Models Shows relationships between entities An entity is a person, place, or thing Items listed inside the boxes are fields The lines drawn between the boxes represent the relationship between entities The etchings at the ends represent the relationships
