How do you source the information
The process of computerisation of the establishment
is going to be expensive in terms of both money
and time.
Most businesses will need a combination of
industry software for the specialist information sub
systems and some general software such as
spreadsheets; word processing and communication
programs. The general packages can be found in
general computer stores.
However the software that is a little more
specialised will take a little more effort to locate.

Finding Software
The following can be used as a starting point.
• Internet - ie www.ehotelier.com/www.micros.com
• Shows and Exhibitions
• Trade magazines
• Consultants
• Colleagues in the industry
• Yellow Pages
• Industry bodies
• Other suppliers

2. Operating system
3. Interface
4. User friendliness
5. Industry standard
6. Speed
7. The software company size
8. Support

9. Help systems
10. Training Sources
11. Local conditions
12. Robustness
13. Do the programs communicate
14. Other user’s comments are useful
15. Special Interest Groups (SIG)
10
Custom designed
In some cases an off-the-shelf solution is not
possible. This may be because the information or
operational needs are unique, the scope of the
program is unique, or the establishment requires a
one program solution to suit a variety of
information sub systems. It is therefore necessary
to hire a developer or programmer to write the
software that will collect the data and produce the
necessary information.
11
How do you assess what you need?
The best starting point is the current information
system. If the business is new then the task becomes
a little more complicated. The current reports provide
a good starting point. What are the good points and
what are the bad points about the current reports?
Are there any new reports required?
Are all reports used?
Where is the data collected in the current system?
12
How do you justify what you need?
• Accuracy
of information
• Decentralised data entry
• Reduced operational costs
• Improved presentation of information
• Expanded range of services
• Improved communication system
13
Considerations against computer
systems
• Set
up costs
• Maintenance costs
• Training and re-training
• System monitor and control
14
Few Operating Systems
 VISTA
 Windows XP
 Unix
 Linux
 Mac OS X
 Palm OS
 Windows CE
15
Activity
 Research a few different brands of computer
equipment (refer to slide 2). List the features and
prices for each.
Take the printout and keep it for the project.
16
Basics kinds of computers
 A computer is a programmable machine (or more
precisely, a programmable sequential state machine).
There are two basic kinds of computers: analog and
digital.
 Analog computers are analog devices.. An analog
computer can represent fractional or irrational values
exactly, with no round-off. Analog computers are
almost never used outside of experimental settings.
 Digital computer is a programmable clocked sequential
state machine. A digital computer uses discrete states.
17
Memory
 Main storage is also called memory or internal
memory (to distinguish from external memory, such as
hard drives).
18
RAM
 Random Access Memory, and is the basic kind of
internal memory. RAM is called “random access”
because the processor or computer can access any
location in memory
19
ROM
 Read Only Memory (it is also random access, but only
for reads). ROM is typically used to store things that
will never change for the life of the computer, such as
low level portions of an operating system.
