<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>From a programming point of view, a 2-d array is
probably much more like a spreadsheet than a database table.</FONT></DIV>

programming languages and necessary programming skills for 2011 (adapted from
VCE Bulletin #80, June 2010) <BR><BR>"In the development of solutions,
students should be able to:<BR>• develop a graphical user interface (GUI), for
use in mobile computing devices, such as laptops, personal digital assistants,
gaming consoles, mobile phones<BR>• construct and use data structures, for
example multidimensional arrays, strings, sets, lists, tables, records, queues
and stacks<BR>• design, construct and use files (not databases) to store and
retrieve data<BR>• design and apply data validation techniques<BR>• use
program control structures: selection, iteration and sequencing.<BR><BR>The
purpose-designed software will entail the use of objects, methods and their
