[Year 12 SofDev] Approved programming languages for 2011

Sun Jul 4 19:05:58 EST 2010

Hi Folks,

 I wonder if the inclusion of records has caused the expectation that record
design is done in a table ?
Also, a queue or stack is effectively an array ( or vector ) of records
which would need a table as the design tool.

.	construct and use data structures, for example multi-dimensional
arrays, records, queues and stacks

Kind Regards

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!
