3 3 Chapter 1 Introduction to Databases Transparencies

4 4 Pengantar Sistem Basis Data Tujuan : u mempelajari konsep dasar tentang database u analisis data menggunakan model relasional u penggunaan instruksi SQL untuk mengoperasikan suatu database Buku : Connolly, T.M., and Begg C.E.. (2002). Database Systems: A practical Approach to Design, Implementation, and Management. 3rd Ed. Addison Wesley.

5 5 Pengantar Sistem Basis Data Silabus : u Ch. 01 : Pengantar tentang database u Ch. 02 : Database environment u Ch. 03 : Model Relasional u Ch. 05 : SQL: Data Manipulation u Ch. 06 : SQL: Data Definition dan View u Ch. 09 : Perencanaan, Desain dan Administration Database u Ch. 10 : Penemuan Fakta u Ch. 11 : Entity-Relationship (ER) Modeling u Ch. 12 : Perluasan E-R u Ch. 13 : Normalisasi Data

6 6 Pengantar Sistem Basis Data Tatacara di kelas  Kuliah sesi 1 : Pengantar Pembentukan Kelompok  Mulai minggu ke 2 – dst (optional) : Kuis Pembahasan materi Diskusi kelompok Presentasi kelompok

7 7 Pengantar Sistem Basis Data Peta konsep materi kuliah

8 8 Chapter 1 - Objectives u Some common uses of database systems. u Characteristics of file-based systems. u Problems with file-based approach. u Meaning of the term database. u Meaning of the term Database Management System (DBMS).

9 9 Examples of Database Applications u Purchases from the supermarket u Purchases using your credit card u Booking a holiday at the travel agents u Using the local library u Taking out insurance u Using the Internet u Studying at university

10 10 File-Based Systems u Collection of application programs that perform services for the end users (e.g. reports). u Each program defines and manages its own data.

11 11 File-Based Processing

12 12 Limitations of File-Based Approach u Separation and isolation of data –Each program maintains its own set of data. –Users of one program may be unaware of potentially useful data held by other programs. u Duplication of data –Same data is held by different programs. –Wasted space and potentially different values and/or different formats for the same item.

13 13 Limitations of File-Based Approach u Data dependence –File structure is defined in the program code. u Incompatible file formats –Programs are written in different languages, and so cannot easily access each other’s files. u Fixed Queries/Proliferation of application programs –Programs are written to satisfy particular functions. –Any new requirement needs a new program.
