Title: RMM methodology applied to the Atles de les Illes Balears


1
RMM methodology applied to the Atles de les Illes
Balears
  • Josep Blat and Toni Navarrete
  • Doctorat Informàtica i Comunicació

2
Aims
  • Reviewing RMM concepts
  • Improvements to the methodology
  • Application to the Atles de les Illes Balears

3
RMM RMDM Model
  • E-R Model navigational structure
  • Primitives of the model
  • domain primitives
  • represent relationships and data structures
  • access primitives
  • represent navigation

4
RMM RMDM Model
  • Domain Primitives
  • entities
  • relationships
  • slices subsets of entity attributes with a unity

5
RMM RMDM Model
  • Access Primitives
  • conditional index
  • conditional guided tour
  • conditional indexed guided tour
  • grouping (for menus)

6
RMM. Methodology steps
  • Step 0
  • Feasibility study and requirements analysis (both
    of information and navigation)
  • Hardware and software selection

7
RMM. Methodology steps
  • Step 1 E-R design
  • E-R Model as usual except
  • NM relationships are divided into two 1N
    relationships
  • The goal is to make future navigational links
    explicits

8
RMM. Methodology steps
9
RMM. Methodology steps
  • Step 2 Slice design
  • Divide the attributes of an entity into
    meaningful subsets
  • They should allow better structuring of screens
    versus big screens requiring scrolling )
  • Slices linked via structural links
  • Decide the slice head

RMM. Methodology steps
  • Step 3 Navigational design
  • Relationships are replaced by access primitives
    (decision is a navigational design decision)
  • Choose the slice which is the destination of link
    (the default one is the slice head)
  • Organise the menu hierarchy through the grouping
    primitive
  • rule avoid too many depth levels which induce
    user disorientation

12
RMM. Methodology steps
13
RMM. Methodology steps
14
RMM. Methodology steps
  • Steps 4 to 7
  • Step 4 Conversion protocols design
  • Protocols to transform each RMDM element in the
    platform selected
  • Example entities to tables, indexes SQL queries,
    ...
  • Step 5 Graphical interface design
  • Design of each screen from the slices
  • Step 6 Run-time behaviour design
  • Algorithms for history, backtracking,...
  • Step 7 Construction and tests

15
RMM modifications (by the same authors)
  • Enlarging the model to make it really useful.
  • Three new types of slices
  • Minimal
  • Hybrid
  • M-slices

16
RMM modifications
  • Minimal
  • Attributes allowing identification of entity by
    user
  • Used as default anchor of entity
  • Hybrid
  • Combining attributes of different entities
    allowed
  • Allows more flexible presentation on screens.

17
RMM modifications
  • m-slices
  • hybrid slices allowed to contain other m-slices

18
New patterns
  • Hierarchical accesses
  • Acces in NM relationships
  • Multiple access primitives
  • New simple access primitives
  • Simultaneous access
  • to all elements of an entity
  • Random access
  • Random access to an element of an entity

19
New patterns
  • Hierarchical accesses
  • When several 1N relationships on a chain, infer
    and enable navigation down the hierarchy
  • Represented by discontinous lines

20
New patterns
  • Acces in NM relationships
  • Navigation allowed, keeping the intermediate
    entity, usually with a hybrid slice

21
New patterns
  • Multiple access primitives

22
New patterns
23
Atles de les Illes Balears
  • Thematic atlas of Illes Balears
  • CD-ROM application with web interface
  • several windows to enable analysis
  • user-friendliness
  • DB impossible
  • Based on RMM
  • Quite rich structure

24
Atles de les Illes Balears
  • Elements in the application
  • Texts 960
  • Maps 686
  • Graphics 283
  • Tables 148
  • Pictures 288
  • Videos 72
  • Panoramas 23
  • Total 2460

Jerarquía de menús
32
Atles de les Illes Balears
  • Step 4 Conversion protocols design
  • No DB
  • Directory structure and file naming conventions
    to imitate that
  • Step 5 User interface
  • Windows, frames and tables.
  • Menu accessibility (supporting thematic structure)

33
Atles de les Illes Balears
  • Step 6 Run-time behaviour
  • Algorithms and programs for navigation control,
    history, window control, ...
  • JavaScript based (Daniel Soto)

34
Atles de les Illes Balears
  • Step 7 Construction and tests
  • HTML and JavaScript
  • One Java applet and three VRML models of the
    islands
  • Tests
  • extensive testing
