Peoplesoft Fundamentals David Lewis 10/18/02 (adapted from Psoft Training Materials)
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 • http://comwebserver.uml.edu:8080/psp/
Benefits of Internet Architecture • Easy Access • Platform Independence • Look and Feel • Low Bandwidth Access • Maintenance/Deployment • Cost effective
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
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
PeopleSoft Internet Architecture • Four components • Internet access device • Web Server • Application Server • Database Server • Similar to other others: ex. Amazon
Architecture issues • No software to install on the clients • No plugins necessary • Simple, open architecture
Web Server • Purpose • Relay data from Browser to Application Server • Handle encryption • Serve up the image • Connection between Browser and Application Server
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
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
Database server (cont.) • Application data tables: contain data created by the user
Peoplesoft and UML • UML (as part of UM) is implementing • HR (March 2002) • Financials (july 2002) • Student administration (with Dart and Bos) • Currently changing over from old to new Financial System
PeopleSoft and UML • COM: received a grant (with 2Million) from PeopleSoft • Currently: Full Financials package • Goal: Use as an ERP “tool” (PP, Access) • Called: End User Training • Also, Application Development available • Here: Intro to Navigation and Report Writing • May see in later classes
Relational Database Basics Adapted from PeopleSoft Training Materials Oct 2002
Basic Characteristics • Standard for efficient data organization • Store data based on true characteristics • Looks at how data items relate to each other • Each item stored just once
Relational Databases • Files called tables in PeopleSoft • Key fields: uniquely identify a row (record) • Indexes of keys make data storage and retrieval more efficient
PeopleSoft Data Models • These are set up by PeopleSoft • One model for each function • Samples next page
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
