10. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-10 Chapter Objectives To understand the nature and characteristics of databases To survey some important and interesting database applications To gain a general understanding of tables and relationships To describe the components of a Microsoft Access database system and explain the functions they perform To describe the components of an enterprise-class database system and explain the functions they perform To define the term database management system (DBMS) and describe the functions of a DBMS

11. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-11 Chapter Objectives To define the term database and describe what is contained within the database To define the term metadata and provide examples of metadata To define and understand database design from existing data To define and understand database design as new systems development To define and understand database design in database redesign To understand the history and development of database processing

12. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-12 The Characteristics of Databases The purpose of a database is to help people track things of interest to them Data is stored in tables, which have rows and columns like a spreadsheet. A database may have multiple tables, where each table stores data about a different thing Each row in a table stores data about an occurrence or instance of the thing of interest A database stores data and relationships

13. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-13 Naming Conventions in this Textbook Table Names are written with all capital letters: –STUDENT, CLASS, GRADE Column names are written with an initial capital letter, and compound names are written with a capital letter on each word: –Term, Section, ClassNumber, StudentName

14. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-14 Data in Tables

15. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-15 The Key Characteristic of Databases: Related Tables

16. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-16 Databases Create Information Data = Recorded facts and figures Information = Knowledge derived from data Databases record data, but they do so in such a way that we can produce information from the data –The data on STUDENTs, CLASSes and GRADEs could produce information about each student’s GPA

17. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-17 Database Examples

18. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-18 Components of a Database System: Microsoft Access

19. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-19 Microsoft Access Microsoft Access is a low-end product intended for individual users and small workgroups MS Access tries to hide much of the underlying database technology from the user A good strategy for beginners, but not for database professionals NOTE: MS Access is discussed in detail in Appendix A

20. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-20 MS Access in Detail

21. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-21 Example SQL SELECT StudentNames, EmailAddress FROM STUDENT Where StudentNumber > 200 If Exists ( SELECT * FROM SYSOBJECTS WHERE [Name] = ‘CLASS’ AND type = ‘U’) DROP TABLE CLASS

22. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-22 Applications, the DBMS and SQL Applications are the computer programs that users work with The Database Management System (DBMS) creates, processes and administers databases Structured Query Language (SQL) is an internationally recognized standard database language that is used by all commercial DBMSs

23. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-23 What Is MS Access? MS Access is a DBMS plus an application generator: –DBMS creates, processes and administers MS Access databases –The application generator includes query, form and report components The MS Access DBMS engine is called Jet, which is not sold as a separate product MS Access 2000 and later can be used as an application generator for the MS SQL Server DBMS

24. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-24 Enterprise-Class Database Systems

25. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-25 Prominent DBMS Products Microsoft Access Microsoft SQL Server –New: Microsoft SQL Server ExpressMicrosoft SQL Server Express IBM DB2 Oracle Corporation ORACLE And don’t overlook MySQLMySQL

27. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 1-27 The Database A database is a self-describing collection of integrated tables The tables are called integrated because they store data about the relationships between the rows of data A database is called self-describing because it stores a description of itself The self-describing data are called metadata, which is data about data
