Hello

I realize that the following questions might seem totally irrelevant
to most of you, but I'm still hoping someone will take the time to
answer them.

BTW - I will use IS for information system


On one of the pages my book talks briefly about IS ( but it never
explains what exactly does it mean with the term - is the text
referring to DBs only, or to computer based systems or ...) and explains
that IS is made of several components. It also mentions that we divide
IS into several categories. Anyways:

a) What are the IS components?
b) Into what categories do we divide IS?


thank you

You would probably have to ask the author(s) what they meant when they
wrote that. If one uses the ISO standard vocabularies, then an
information system necessarily can encompass more than a DB because the
standard vocabularies treat data as only that subset of information
suitably represented for machine processing.

Hence, a physical books and shelves library can be or can be part of an
information system.

Well, the author most probably mean Is in the more general sense of a
word, so...

An Information System or IS as you call it may have some of the
following components:
1) The Human Users - Ultimately they need the Info to do something
2) The Data Source - can be a DB, or physical paper files, or books
catalogs etc. as mentioned by Bob
3) The Processing System - That turns the data into Information. It
applies the varies rules and contraints to the data to make it more
meaningful.
4) The Reporting System - May be part of the Processing component,
used to properly provide the Information to the intended users in
desired format and on time.
DBMS tools and application programs are written/used to make the whole
process fast, able to handle huge volumes of data, and error free (to
the extent possible).
