Weeks 10 and 11 - Expertise and expert systems
In these two weeks we will consider what is meant by expertise, and how we can capture expertise in order to transfer the skills of an expert into a system that can be used by non-expert users in order that they can have the benefit of expert advice.
what is meant by point 11 in the indavidual work could you please explain weather you want us to create an interface indavidualy ,.
ReplyDeletePoint 11 is:
ReplyDelete11. Technical Design (up to 2 pages) Present the technical details of the solution design, clearly identifying the data it uses and explaining how this data is transformed to produce useful information. This section should make use of one or more recognised design technique(s), e.g. Decision table/tree, STD, ERD, DFD, task analysis, flow chart, any UML techniques, etc.
This means you should explain how your query/report works.
Section 9 asks you to identify the stakeholders, their critical success factors and their information requirements (what they need to know in order to make a decision).
Section 10 asks you to identify the data used (you might not be querying all the data in the ERD, only a subset), and outline the tranformation processes (i.e. you might be selecting data that meets some criterion and calculating sub-totals and totals.
Section 11 asks you to explain how the query works, so you might need to refer to more than one table (entity) in order to extract and process the data stored to produce information. Printing a list of 200 orders isn't information; printing how many products were sold in each category over a specific time period is - and this kind of information can be show in the Excel part of the assignment in order to show how different products or product categories compare against each other, over time...
Point 15 relates to the interface - a switchboard is fin for Access, but you will need another approach for Oracle (e.g. a file with queries that the user can cut-and-paste into SQLplus).
WHAT YOU MEAN BY TRANSFORMATION PROCESS
ReplyDeleteA transformation process is the way in which you have chosen to convert the data into information, for example by sorting, calculating totals, selecting on the basis of certain criteria, etc.

ReplyDeleteFor the individual contribution are we meant to write the report as if the allocated tasks have been completed or as they are being done.
Example: Mona is doing the oraganistaion chart so would i say she was given the task to create it and the steps she took to complete it or would she say this is what she is doing now.
Hi Marina
DeleteI would expect each member of the team to explain what they have done, so that by the time the work is submitted, it will have been finished!
