Definition of a computer program
A computer program is a sequence of instructions
(codes) written to perform a specified task with the
help of a computer.
This program be written by using programming
languages such as Java, C++, ...

7. Programs and Software

Software is a set of computer programs, procedures and related
documentation and data (ISO/IEC 12207).
Software
Program

8. Software and software products

Software = program + documentation + [...].
The software product is the business software
which the main target is marketability and satisfy
the customer needs.
Marketability shows the commercial success of
software development.

9.

Software tools
A software tool is a set of logically related programs
that allows you to create programs and documentation
provided with the software.
- it is a computer program that software developers use
to create, debug, maintain, or document and support
other programs and applications
In a software tool a program and its documentation are
closely interrelated.
Ex: case tools (UML), a source code editor and
a compiler or interpreter, Code analysis tool

10. What is a system?

11. System: Definition

A system is a set of integrated
components
associated (interrelated ) with each other and with the
environment in an orderly manner. It is selected for a
specific purpose to perform specified functions for
obtaining a specific beneficial result (objective).

12.

Information system
is a hardware and software system
designed to automate the end-user
activities, by providing the ability to
obtain, modify, and store information.

13. WHAT IS INFORMATION SYSTEM?

• An information system (IS) is an arrangement of people,
data, hardware, software connectivity processes, and
information technology that interact to collect, process,
store, and provide as output the information needed to
support an organization.
• An information system can be defined technically as a set
of interrelated components that collect (or retrieve),
process, store, and distribute information to support
decision making and control in an organization.

15.

Main processes of IS

16. The main aim of an Information system

•is satisfying specific information needs
within some domain.
•Modern IS cannot function without the
use of databases and database
management systems.

19. Information system

Any information system has the following subsystem
types:
• Subsystem of store data and information provision (data);
• Subsystem of intellectual provision
(information, knowledge, Business idea);
• Subsystem of technical provision (devices);
• Subsystem of technological provision (technologies, IT
infrastructures)

20. Perspectives on Information Systems

Information system:
• Set of interrelated components
• Collect, process, store, analyze, and distribute information
• Support decision making, coordination, and control
Information vs data:
• Data are streams of raw facts
• Information is data shaped into a meaningful form

21. Perspectives on Information Systems

Data and information
Raw data from a supermarket checkout counter can be processed and organized to
produce meaningful information, such as the total unit sales of dish detergent or the total
sales revenue from dish detergent for a specific store or sales territory.

22. System management functions in IS

• Planning
• Accounting
• Analysis
• Control
• Regulation
• Prediction

23. IS Classification

According to architecture:
• File-server (File Servers are useful for sharing information across
the network)
• Client-server
• Multi level
According to information use:
• Information search systems
• Information management systems
23

24. IS Classification

According to functions:
• TPS – Transaction Processing System
• MIS – Management Information System
• DSS – Decision Support Systems
• ES – Expert Systems
24

25. IS Classification

by technology and management standards
• MRP - Material Requirements Planning
• MRPII - Manufacture Resource Planning
• ERP - Enterprise Resource Planning
• SCM - Supply Chain Management
• ERPII - Enterprise Resource & Relationship Processing.
• CRP - Capacity Requirements Planning
• CRM - Customer Relationship Management.
• PM - Project Management
• CALS - Continuous Acquisition and Lifecycle Support

26. Corporate IS

In recent years there has been a growing demand for
corporate IS
For instance there are payments IS, health care IS, labor
exchange IS.
All duties in our life now are proceeding and managed
depending on variety types of IS
ERP systems (integrated system)

27. Sample of Question

• Define the concept of IS, components of IS, main types of IS
• Explain the difference between Computer program and Systems
Software
