Fundamentals, Design, and Implementation, 9/e Chapter 1 Introduction to Database Processing

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/12 Copyright © 2004 Why Use A Database?  The purpose of a database is to help people and organizations keep track of things  Problems of using list to store data –Data inconsistencies –Data privacy: The departments want to share some, but not all, of their data  Databases store data in single-theme tables  Tables are related through primary and foreign keys

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/13 Copyright © 2004 Components of A Database System

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/14 Copyright © 2004 Application Programs  Functions: –Create and process forms –Create and transmit queries –Create and process reports –Execute application logic –Control application

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/15 Copyright © 2004 DBMS  DBMS: Database Management System  Functions: –Create database, tables, and supporting structures –Read and update database data –Maintain database structures –Enforce rules –Control concurrency –Provide security –Perform backup and recovery  Example: Oracle, DB2, Microsoft Access, SQL Server

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/16 Copyright © 2004 Database  Database is a self-describing collection of related records or tables  Components: –User Data –Metadata: data about the structure of a database –Indexes and related structures –Stored procedures: program modules stored within the database –Triggers: a procedure that is executed when a particular data activity occurs –Application metadata: data describing application elements such as forms and reports

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/17 Copyright © 2004 Types of Database  Personal database –1 user; < 10 MB  Workgroup database –< 25 users; < 100 MB  Organizational database –Hundreds to thousands users –>1 Trillion bytes, possibly several databases

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/18 Copyright © 2004 Example: Organizational Database

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/19 Copyright © 2004 Building a Database System  3 Phases  Requirements phase: a data model is developed –Data model is a logical representation of the database structure  Design phase: the data model is transformed into tables and relationships  Implementation phase: –Tables, relationships, and constraints are created –Stored procedures and triggers are written –The database is filled and systems are tested  Database and its applications will be modified (through these same three phases) to meet new requirements

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/20 Copyright © 2004 Example: Data Model

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/21 Copyright © 2004 Application Development  Application development proceeds in parallel with database development

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/22 Copyright © 2004 History of Database Processing

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/23 Copyright © 2004 Early Database Models  Before mid-1960s, only sequential file processing using magnetic tape was possible  In mid-1960s, disk storage enabled hierarchical and network database –IBM’s DL/I (Data Language One) –CODAYSL’s DBTG (Data Base Task Group) model  the basis of current DBMSs

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/24 Copyright © 2004 The Relational Model  E.F. Codd introduced the relational model in 1970  DB2 from IBM is the first DBMS product based on the relational model  Other DBMS based on the relational model were developed in the late 1980s  Today, DB2, Oracle, and SQL Server are the most prominent commercial DBMS products based on the relational model

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/25 Copyright © 2004 Personal Computer DBMS  The advent of microcomputer increases popularity of personal databases  Graphical User Interface (GUI) make it easy to use –Examples of early DBMS products: dBase, R:base, and Paradox

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/26 Copyright © 2004 Object Oriented DBMS (OODBMS)  Object-oriented programming started in the mid-1980s  Goal of OODBMS is to store object-oriented programming objects in a database without having to transform them into relational format  Object-relational DBMS products, such as Oracle 8i and 9i, allow both relational and object views of data on the same database  Currently, OODBMS have not been a commercial success due to high cost of relational to object- oriented transformation

Database Processing: Fundamentals, Design and Implementation, 9/e by David M. KroenkeChapter 1/27 Copyright © 2004 Recent History  Success story of the Microsoft Access –Microsoft Office suite and Windows integration –Easy-to-use and powerful personal DBMS  Internet database  XML and database integration
