• Where are we?
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)

EMA pt 1
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

WHAT DO
WE KNOW?
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
10
• Even a grade 4 pass is something to be proud of!
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
11
•
•
•
•
•
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”
12
• You have seen both sides of an e-business implementation
• And can communicate effectively with all those involved
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
13
• And concentrated on XML and XML schemas
• Completing a realistic exercise in the TMA
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
14
• XML knowledge is valuable – sell it!
• But there is a depth and subtlety that remains to be found
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
15
• A good, appropriate functional breakdown is the key to
many a successful system…
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
16
• These days, every system is a distributed system!
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
17
• Building on all the knowledge that you have gained in all
the previous blocks
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
18
• 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

Body
Background, facts, information
21
Conclusion
Recommendations using information from
above
EMA SECTION 2
• XML schema and instance documents - 5 marks
•
• Very similar to parts of TMA02
XML solution discussion - 10 marks
•
• Material from Block 2
Evidence of BPEL orchestration solution
•
• Stage 1 only - 8 marks
• Similar to block 4 practicals 1a, 1b, 2 & 3
• Stage 1 & 2 - 16 marks
• Includes items from other block 4 practicals
BPEL orchestration discussion – 12 marks
22
• Material from block 4
Look carefully at the mark breakdown!
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”
23
• EMA Booklet 1 Page 12
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
24
• 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
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!
28
• Move on to other parts of the EMA
“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.
29
WHAT
NEXT?
• EMA Submission Date 3rd October – NO EXTENSIONS!
• If there are circumstances beyond your control that may affect
your ability to complete the EMA properly
• Submit a PT39 “Special Circumstances” Form
BEFORE THE DEADLINE
• “Verification” – Mid October
• Marking – Late October
• Final Grades – ???
• Any questions or problems email [email protected]
THANK YOU FOR WATCHING!
