Introduction

• Name
• Where youre from
• Something you would change about your job if you
  could, apart from more money/less work
• Something you love about your job, apart from the
  holidays

3
Why was the syllabus amended?

• There was a strong feeling that
• there was too much content, especially in the
  preliminary course (also removed to avoid
  duplication of concepts in HSC?)
• Learn abouts/Learn tos -clarify definition of
  terms and concepts and remove ambuguities
• there was a need to update because of the
  rapidity of change in hardware, software and the
  way it is used
• (Need slide Syll.P.9 Course Structure)?

Whats new?

• How extensive are the changes?
• What is the general nature of the changes?
• Why is it smaller?

Whats new?
Changes to the preamble reflect a desire to
strengthen the requirements relating to project
work. Other changes reflect structural changes in
the course. More time has been allowed for
students to complete Tools for Information
Processes. The topics Planning, Designing and
Implementation and Personal and Group Systems
and Projects have been replaced with one topic
called Developing Information Systems. This
has been done to remove duplicated and irrelevant
content and concepts, and to provide more time to
integrate content into project work. In the HSC
course, some topic headings and subheadings have
been renamed to remove ambiguities that existed
in the original syllabus.

11
Whats not?

• The syllabuss orientation around how information
  systems work and how they are developed
• Students are expected to be competent, confident,
  ethical users of IT
• The project-based nature of the subject
• Much of the content, including IPT specific
  jargon

Optional slide

• Depending on where you look,
• On line transaction processing
• This refers to optimising databases to improve
  online performance.

According to http//www.databasejournal.com, this
optimising consists of organising the data into
layers.

• Business logic layer rules and procedures,
  optimised so that frequent requests are handled
  fast

• Data layer all data needed to process
  transactions

• Presentation layer the only thing that happens
  at the clients end

23
Optional slide

• On line analytical processing
• OLAP speeds up the process of querying relational
  databases. In the past, this has been a slow
  process because properly normalised databases
  have data stored in discrete tables. It does this
  by pre-building sets of data based on a snapshot
  of the real database. File size blows out
  enormously because the data is no longer
  normalised, but query speed is much higher.
• It comes in three delicious flavours
• Molap
• Rolap
• Holap

• On line analytical processing
• Drilling down refers to taking a generalised set
  of results and looking more deeply at a part of
  those results. For example, The rainfall in May
  was high. Did it rain all month or come in
  bursts?. Drilling down further could look at an
  hour by hour or minute by minute analysis of the
  rainfall.

• Decision support systems
• New things here include Group decision support
  systems, geographic information systems and
  management information systems

• Nearly all the changes have occurred in the
  course Specifications document.
