PROPOSED UN-AGENDA(?)• The practical work

• Everyone is at a different stage• Thoroughly described in Block material• Excellent support from the appropriate national forums• Best worked through at your own pace (IMHO)

IN CASE OF EMERGENCY…

You have 2 ½ weeks remaining - Do not panic!

• If you haven’t started block 4 -

• Skip it (big block, lot of work)• Complete EMA section 1 and headings 1 & 2 of section 2• See what else you can manage in the time available

• If you did not submit the work plan –

• Create one now• Add it, and your reflection on it, to your EMA

Contact your tutor if you have any questions or problems

(More on the EMA later…)

WHAT DO WE KNOW?

“I DON'T APPRECIATE THE INSINUATION, LONGBOTTOM. BESIDES, IF ANYONE CARES TO NOTICE, MY EYEBROWS HAVE COMPLETELY GROWN BACK.”

10

FIRSTLY - BE PROUD!• T320 is a level 3 course – it is supposed to be hard!

• This is not a course on which everyone routinely scores 90+ on their TMAs

• You are working at the highest undergraduate level

• To get to this stage you have already demonstrated an excellent level of commitment, learning and effort

• Even a grade 4 pass is something to be proud of!

11

BLOCK 1 – E-BUSINESS• We learnt about “business models”

• How to use models to describe, categorise and compare a business and the way it relates to web technologies

• We looked at various case studies

• E-business has evolved enormously (even over the lifetime of this module)

• We completed TMA01

• This was a hard TMA!• We had to decide on our own answer• Find evidence to back up our arguments• Use an academic style• All within a very limited word count

12

BLOCK 1 – OUTCOMES• You can understand how business models are used

• And derived your own opinions on how useful they are

• You can read (and appreciate) academic papers

• And have taken some small steps towards writing one

• You have started to bridge the gap between “the business man” and “the technologist”

• You have seen both sides of an e-business implementation

• And can communicate effectively with all those involved

13

BLOCK 2 – PROTOCOLS AND DATA• You have looked at standards

• Why they exist• How they are developed• How they are used

• We have looked at many ways to encode data

• And concentrated on XML and XML schemas• Completing a realistic exercise in the TMA

14

BLOCK 2 – OUTCOMES• You should be able to appreciate that data representation

is a non-trivial issue

• And have some basic understanding of data representation schemes

• You have seen standards in action

• And can articulate the benefits and problems with them

• You have carried out some basic data design

• XML knowledge is valuable – sell it!• But there is a depth and subtlety that remains to be found

15

BLOCK 3 – WEB SERVICES• You looked in detail at the Web Services Protocol Stack

• And saw lots of acronyms!

• You learnt about UDDI

• The problems UDDI was intended to solve still exist

• You carried out a realistic web service decomposition

• A good, appropriate functional breakdown is the key to many a successful system…

16

BLOCK 3 – OUTCOMES• Specifically you have an understanding of WSDL style

web services

• Further extending your knowledge of XML

• More generally you have an appreciation of many of the “big issues” in distributed systems:

• Discovery and definition• Reuse and granularity• Scalability and resilience

• These days, every system is a distributed system!

17

BLOCK 4 – ORCHESTRATION• You have learnt how to read BPMN diagrams

• And to a more limited extent, how to construct them

• You have considered the need for orchestration and choreography in constructing the high level system

• And you have implemented a (hopefully!) working example of a BPEL process

• Building on all the knowledge that you have gained in all the previous blocks

18

BLOCK 4 – OUTCOMES• BPEL implementation skills are in limited demand

• But the practicals and EMA between them allowed you to demonstrate a deep understanding

• You have learnt and demonstrated a detailed, technical skill

• More practically, you have understood BPMN

• If you are not afraid of BPMN then you should have no fear of UML (Unified Modelling Language)

• A very widely used set of diagramming tools

23

EMA TIPS - 1• Hand Something in!

• No submission = definite fail Submission = possible pass!• There are no tricks or traps!

• You can take everything you see at “face value”• Word count limits

• But not too challenging – 2500 “content” words• Organise your report to help your marker!

• Follow suggested headings in EMA Booklet 1 Page 10• Carefully read (and follow) “What to submit”

• EMA Booklet 1 Page 12

24

EMA TIPS - 2• The deadline is fixed, no submission possible after cut-off

• But unlimited submissions allowed before that• So submit early versions in case of problems later• Only the most recent version will be marked

• Keep up to date with the T320 website

• Check the news section• Take a quick look through the EMA forums• Strongly recommend doing this about 1 week before

deadline• Check that you haven’t missed anything• Watch recording of nationwide BPEL Tutorial

HOW TO GET MORE HELP

“ I WAS MOST UNFORTUNATE IN MY YOUTH TO COME ACROSS A VOMIT FLAVOURED ONE. I MUST SAY SINCE THEN I HAVE LOST MY LIKING FOR THEM.”

28

GETTING HELP• Read the national forums

• Your question may have already been asked!• Post in the national forums

• Try to provide detailed information, specific question• But not your actual answers(!)

• E-mail me – I can answer two types of question:

• “Have I understood the question?” (Yes or no only!)• “Can you help with this very specific problem?”

• Don’t get fixated, or give up!

• Move on to other parts of the EMA

29

WHAT NEXT?

“NOW IF YOU TWO DON'T MIND, I'M GOING TO BED BEFORE EITHER OF YOU COME UP WITH ANOTHER CLEVER IDEA TO GET US KILLED - OR WORSE, EXPELLED.
