HSC IPT Introduction to Information Systems & Databases

1. Information Processes
HSC On line with
Mr Cusack
and Technology

2. Lesson Topic
T1W2 – Information Systems and
Databases

3. Information systems are computer systems
that support end users, giving them access to
the information.

4. Information systems are computer systems
that support end users, giving them access to
the information.
For a large number of information systems,
the data is held in databases and access is via
database management systems (DBMS)

5. Information systems are computer systems
that support end users, giving them access to
the information.
For a large number of information systems,
the data is held in databases and access is via
database management systems (DBMS)
Two types of database:
Flat file: All of the data is stored in one big
file. This results in a large file with much
repeated (redundant) data

Two types of database:
Flat file: All of the data is stored in one big
file. This results in a large file with much
repeated (redundant) data
Relational: The data is split up into separate
related tables and linked together using a
relationship schema.

7. CHARACTERISTICS OF INFORMATION SYSTEMS
Information systems are created to provide
information to a person or organisation.

8. CHARACTERISTICS OF INFORMATION SYSTEMS
Information systems are created to provide
information to a person or organisation.
The characteristics of an information system are:
The organisation of data into information.
A data dictionary is a tool used to help organise the
data.

Analysing the information to give knowledge
Tools used for analysing data are tables, queries and
reports

10. FUNCTIONS OF INFORMATION SYSTEMS
Processing transactions:
batch processing and real-time processing.

11. FUNCTIONS OF INFORMATION SYSTEMS
Processing transactions:
batch processing and real-time processing.
Providing users with information about an
organisation.
This involves the production of reports on
sales, inventory, payroll, orders and budgets.

12. FUNCTIONS OF INFORMATION SYSTEMS
Processing transactions:
batch processing and real-time processing.
Providing users with information about an
organisation.
This involves the production of reports on
sales, inventory, payroll, orders and budgets.
Helping decision-making.
A decision support system (DSS) assists people
to make decisions by providing information,
models and analysis tools.

EXAMPLES OF DATABASE INFORMATION SYSTEMS

15. Roads and traffic authority (RMS, Transport
NSW)
This system stores information on registration of
vehicles and holders of driving licences
It now also includes all boating registrations,
licencing etc.

16. Video stores
This system holds information on videos
held in store and borrowers of videos
See the Schema that creates relationships
between the tables
