IF -1312 PRACTICE FOR INTRODUCTION TO DATABASEMODUL 1 – INTRODUCTION TO DATABASE Topic Introduction to Database Objective 1. Students can explain relational database advantage 2. Students can drawing Entity Relationship diagram (ER diagram) use Visio Time 4 sessions Submission submit task 1 to your teacher, submit task 2 (in format vsd) to e-learning Final submission Last session of practice Task 1 Relational Database Advantage Relational database stores and organises data in separate tables instead placing all data in one large (flat file) table. Relational database prevent data duplication, so it can save computer space (memory). We will make experiment to demonstrate that. Step : 1. Take paper 1 with title Flat Database 2. Write by hand all data in table 1 Borrowing book into paper 1. Example : 3 3 1 3 0 1 0 0 1 p r i h a d i i n f o r c h n i q u e 1 d a s a r - d a s a r d r e l a t i o n a l R a m o n A p e n e a n g g a 1 9 9 9 1 a u g u s t 2 0 1 0 0 1 p r i h a d i m a t i c t e a t a b a s e r b i t E r l 4 3 3 1 3 0 1 Explanation : a.

According the experiment. Write by hand all data in table 2 Books.3. Does relational database prevent data duplication ? b. Take paper 2 with title Relational Database 4. and table 4 Borrowing book into paper 2. answer the question : a. How use computer space in relational database versus flat database?
