Hello John
didn't mean to teach you how to suck eggs - didn't know the context of your
question.
But as Adrian says, tables don't get a mention in the new SD course. I am
curious to know which bulletin notice you are referring to?

Exactly, so why does the VCAA Bulletin say:
. construct and use data structures, for example multidimensional arrays,
strings, sets, lists, tables, records, queues and stacks
OK so they do not want us to connect to a table in a DB. That is not a
problem. The problem is that they have listed tables and multidimensional
arrays separately. I was asking, indirectly, "is this an oversight on their
part or is there a data structure called a table that is NOT a 2d array, not
part of a DB, and that somehow I have overlooked for the past 30+ years?"
I'm guessing it is the former.
Thanks
John

Hello John
technically, a table is a data construct for use in a relational database
and nothing else; has an fixed number of columns and an indefinite number of
rows; has a lifetime that goes beyond the life of the application's
execution time; and resides in a long term data store such as a disk drive.
Its contents are generally accessed by matching query criteria, or by moving
to a specific row/record/tuple and then accessing a specific
column/field/attribute. Conceptually, tables are always 2-d but can be part
of a larger structure, the relational database, wherein many tables are
related to each other in some way.
while a 2-d array is a data construct for use in a program and is general
purpose; (generally) has a fixed number of columns and rows; has a lifetime
that does *not* go beyond the execution time of the program; and resides in
memory. Its contents are generally accessed directly by targeting a specific
cell via 2 indexes. Conceptually, 2-d arrays are a specific kind of more
general data structure, the array, which can in principle have any number of
dimensions, not just 2.
>From a programming point of view, a 2-d array is probably much more like a
>spreadsheet than a database table.

Hi all,
Please pardon my ignorance but if we are not to use databases, what is the
difference between a table and a 2D (multidimensional) array?

Hi all. I've just got the latest bulletin. Here's a rundown of the
approved languages for 2011...
Approved programming languages and necessary programming skills for 2011
(adapted from VCE Bulletin #80, June 2010)
"In the development of solutions, students should be able to:
. develop a graphical user interface (GUI), for use in mobile computing
devices, such as laptops, personal digital assistants, gaming consoles,
mobile phones
. construct and use data structures, for example multidimensional arrays,
strings, sets, lists, tables, records, queues and stacks
. design, construct and use files (not databases) to store and retrieve
data
. design and apply data validation techniques
. use program control structures: selection, iteration and sequencing.
The purpose-designed software will entail the use of objects, methods and
their properties, and event-driven
programming."
Approved languages
a.. Basic (object-oriented variations only e.g. VB.NET)
b.. C++
c.. C#
d.. Objective C
e.. Visual Fox Pro
f.. Pascal (object-oriented variations only, e.g. Delphi)
g.. Java
h.. Perl
i.. PHP
j.. Python
k.. Ruby
The bulletin also adds, "With all of the above languages, databases are
not to be used to support the construction of solutions."
Note the removal of Real Basic, Visual J and Visual J++, and the addition
of Objective C.
Also note the emphasis on multidimentional arrays and the specific
exclusion of databases: it's good to get that old argument out of the way!
