4. Michelle What’s the coolest car for me? Info need: -What kinds of cars are there? -How do you buy a car? -What do my friends think? -What car suits my personality? -What can I afford ? Info behavior: -Ask my friends & family -Look at a lot of cars and think -Google for certain cars -Look at lots of pictures/videos Info type: Cool Car -Only most basic car facts -Lots of info on styling -Lots of media -Stories and anecdotes -Make it easy to share -Logistics not statistics -Chatty and friendly style

6. Requirements for your Info Type Model 1.At least 2 info types 2.At least one rich text attribute in each type 3.At least 3 controlled vocabs 4.At least 12 tables in the data model Notice the difference between an info type and an entity How will you keep the scope under control?

7. Deliverables for your info Type Model Notes that link the model to the info persona Diagram that – Shows all the attributes of each type – Flags attributes that are rich text controlled vocabs optional Logical design of rich text attributes – Account for inline links for sure – Account for other stuff as needed Physical design: Data model – Showing only the info types modeled (no access structures – Relationships – Keys Be able to discuss and justify your choices

8. User to Access Structure

9. Hierarchies

10. Why would you use a hierarchy? The information The information has categories and sub- categories You want to show the proper names for your information Some pieces of info “inherit” from others The user Wants to know, “What is in here?” Wants an overview of a lot of info Is trying to learn about the information

11. Indexes

12. When do you need an index? When the information has Common attributes (like title or date) Some attributes that clearly divide it (author, keywords, etc.) When the user wants To know “Is it in here?” Quick access to the middle of the information The info sliced by attributes they care about

13. Associations

14. When do you need associations? When the info Natural paths from one item directly to another Is organized like a web When the user Might need to be in one place when she is presently in another place Might be following a scent toward the right info

15. Sequence

16. When do you need a sequence? When the information Has a natural order Is like a story Is like a procedure Has prerequisites or post-requisites When the user Does not know where to start Is trying to do something or learn Needs to see what you want to show them “Needs to see an ad for another item within the current item.

17. Info need: -What kinds of cars are there? -How do you buy a car? -What do my friends think? -What car suits my personality? -What can I afford ? Info behavior: -Ask my friends & family -Look at a lot of cars and think -Google for certain cars -Look at lots of pictures/videos Hierarchy Index Association Sequence Index Sequence Index Association Hierarchy Index (car) Sequence Association Cars by type Cars like this one Other dealers with this car Features Personality trait Uses Owners Price Car name Steps to buying a car Cars we want you to see Top Dealers Index search results Index (dealer) Zip City Name Full text Index Car.longDesc Dealer.longDesc

18. To keep in mind Beware scope creep – I did not model the user on purpose – I did not model steps to buying on purpose You WILL revise this work – Every new thing you do influences all the stuff you have done Might be useful to do some early page sketch's to help you think. – But don’t enslave yourself to them – This is about the info and the user, not the presentation. That comes later

19. Access structure info model requirements Info Model Answers to the AS questions At least one AS of each type Notes and diagrams that link your persona and AS answers to AS chosen Named structures that show their function Data model Add to data model to implement AS Separate data model diagram for each AS – For indexes with no extra tables, show the existing tables that are needed for the index – Include queries if there are one or two key ones – Include a BRIEF logic description if it will take more than a query to work with the data that is retrieved.

20. Access Structure Questions Hierarchy Are there natural categories? Are there a lot of items? Do items behave sometimes as a family (have siblings and parents?) Is the user trying to learn something? Will the user ever want to know what’s in here? Index Are there a lot of items? Are there short attributes (e.g., title and author) that all items of the type have? Are items naturally thought about by the user based on these common attributes (e.g., it is natural to think of articles by author) Are there words that people use to describe items of this type that don’t actually appear in the items (e.g., someone might think “cat” but the items always say “feline”

21. Info Access Association Are there natural paths from one item to others that are related to it? Are there prerequisites to items that should be shown Are there next steps that should be shown Are there words or phrases in the text that should be links? Sequence Is there a natural order to the items of this type? Do some or all items form a sort of story? Do items come together to form procedures? Are there items that you definitely want users to see?
