Describe the benefits of Desktop database and Server database
Select an appropriate DBMS suitable for a given business requirements
Identify the contribution of database technology to society
Activity 1A
Databases and DBMS are an essential component of life in modern society: most of
usedcounter several activities every day that involve some interaction with a
database.For example, if we go to the bank to deposit or withdraw funds, if we make
a hotel or airline reservation, if we access a computerized library catalog to search for
a bibliographicitem, or if we purchase something online such as a book, toy, or
computer chances are that our activities will involve someone or some computer
program accessing a database. Even purchasing items at a supermarket often
automatically updates the database that holds the inventory of grocery items.
1. Why would you choose a DBMS instead of simply storing data in operating
system files?
2. Name few of database names that you know.
3. When would it make sense not to use a DBMS?
Activity 1B
Diagram 1
1. Describe the three level-schema architecture.
2. Why do we need mappings between schema levels?
3. How do different schema definition languages support this architecture?
Activity 1C
There are several different types of databases, but to simplify our discussion,we are
going to suggest that “relational” databases are the primary type of databaseused in
today’s organizations. Relational databases may be broken into twocategories:
1) Databases that run on your desktop computer, and
2) Databases thatare running on a separate server, usually in a different location
from your desktopcomputer.
We will call the first category “desktop databases” and the secondcategory will be
called “client server systems”(Server database). Client server systems are
morecomplicated because there is a program running on your computer (“client”)
thatconnects to the database itself on the server (“server”), and this requires a
network.The explosive development and availability of the internet has provided
thisnetwork to nearly every organization, and client server database systems are
nowwidely available.
1. By reading the text above, discuss the differences between Desktop database
and Server database.
Activity 1D
In a group of 4, identify the contribution of database technology to the society. You
may present your answer by stating sample of real situation(s) that happen in
Malaysia currently.
EXERCISES (CLO1)
1. Discuss the main characteristics of the database approach and how it differs from
traditional file systems.
2. Provide and explain2 examplesof systemsin which it may make sense to use
traditional fileprocessing instead of a database approach.
3. Define client/server architecture.
