Chapter 1Introduction to Database Processing



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



Components of A Database System



Application Programs

Functions: – Create and process forms– Create and transmit queries– Create and process reports– Execute application logic– Control application



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

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



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



Example: Organizational Database



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



Example: Data Model



Application Development Application development proceeds in

parallel with database development



History of Database Processing



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



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



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



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



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
