5. www.brianhitchcock.net Brian Hitchcock February 10, 2008Page 5 What is Oracle Applications?  Oracle Applications is: – Also called Oracle E-Business Suite (EBS) – Huge, takes 100Gb just to install  Doesn’t include database data or staging area – Multiple business applications – System of record  Can’t remove users for example – Built on top of Oracle database (RDBMS) – A mess, you’ll never control it – Great job security  You don’t have to be crazy, but you soon will be…

6. www.brianhitchcock.net Brian Hitchcock February 10, 2008Page 6 Why Use Oracle Applications?  Businesses have (or had) – Multiple business application systems  Peoplesoft for HR  Siebel for CRM (Customer management)  Other apps for orders, manufacturing etc.  ERP (Enterprise Resource Planning) – Provide single system for all business apps – One system of record  Latest trend is a single global instance

7. www.brianhitchcock.net Brian Hitchcock February 10, 2008Page 7 What is ERP?  From wikipedia Enterprise Resource Planning (ERP) systems attempt to integrate all data and processes of an organization into a unified system. A typical ERP system will use multiple components of computer software and hardware to achieve the integration. A key ingredient of most ERP systems is the use of a unified database to store data for the various system modules.

8. www.brianhitchcock.net Brian Hitchcock February 10, 2008Page 8 Oracle EBS Products  Each business application is a ‘product’ Oracle Assets Oracle General Ledger Oracle Payables Oracle Receivables Oracle Cash Management Oracle Bills of Material Oracle Capacity Oracle CRM Oracle Advanced Planning & Scheduling Oracle Purchasing Oracle Business Intelligence Oracle Engineering Oracle HRMS Oracle Inventory Oracle MRP Oracle Order Entry Oracle Order Fulfillment Oracle Payroll Oracle Project Costing Oracle Project Billing Oracle Purchasing Oracle TMS Oracle Work in Process.
