A database is an organized collection of data. The data can be textual, like order or inventory data, or it can be pictures, programs or anything else that can be stored on a computer in binary form.
A relational database stores the data in the form of tables and columns. A table is the category of data, like Employee, and the columns are information about the category, like name or address.
Some databases have minimal feature sets and only store data, while others include programming languages, facilities and utilities to support enterprise-level applications like ERP and data warehousing. Oracle is the #1 database and has the most advanced feature set.
Oracle is made up of a set of processes running in your operating system. These processes manage how data is stored and how it is accessed. I will cover these processes in detail in the future; but for now we just need to understand that Oracle is a program that is running in the background, maintaining your data for you and figuring out where it should go on your hard drive.

What is Oracle Applications?
Oracle Applications comprise the applications software or business software of Oracle Corporation. The term refers to the non-database (non-technology) parts of Oracle Corporation's software portfolio.
Oracle Corporation sells many functional modules which use the Oracle RDBMS as a back-end, notably Oracle Financials, Oracle HRMS, Oracle Projects, Oracle CRM, Oracle PO, etc. (Oracle Corporation also offers many additional application-oriented products, including Oracle Office, Oracle Media Server, and (grouped with databases) Oracle ConText.)
Oracle Corporation initially launched its application suite with financials software in the late 1980s. The offering as of 2009 extends to supply-chain management, human-resource management, warehouse-management, customer-relationship management, call-center services, product-lifecycle management, and many other areas. Both in-house expansion and the acquisition of other companies have vastly expanded Oracle Corporation's application-software repertoire.
Oracle Corporation released Oracle E-Business Suite Release 12 (R12) — a bundling of several Oracle Applications applications — in February 2007. The release date coincided with new releases of other Oracle-owned products: JD Edwards EnterpriseOne, OneWorld, Siebel and PeopleSoft. As of 2009 Oracle Corporation supports Release 11.5.10.X and Release 12.0.X of the Oracle E-Business Suite.
