ITM531/CS524Object Oriented Modeling and Design

• Module 1
• Information Architecture

2
What is information architecture?

• Discipline used in the design and construction
  of information systems, relying on information
  modeling techniques, design practices, database
  standards and architectural strategies.

3
What other disciplines can we learn from?

• Hardware architecture.
• Building architecture.
• Car makers.

4
Example Relational Approach

• Information Model
• Relations
• Quality Controls
• Normalization Theory
• View Supportability Theory
• Design Techniques
• SQL Query language
• View Integration Technique
• NER Construction techniques

5
What is an Information Model?

• An information model consists of a collection of
  data objects, a set of semantic rules and a set
  of operations which when applied to the data
  objects are subject to the appropriate semantic
  rules.

6
Key assumptions

• Store data assumption
• Normalization assumption
• Uniform type assumption
• Structural modeling assumption
• First order logic query assumption
• Knowledge-free assumption

7
Architecture Strategies

• Monolithic Interface (Heterogeneous DBMS)
• Domain Based Libraries (Hypertext / Hypermedia)
• Workflow based (OIS)
• Multi-levels architecture (MLA)
• Project phase Based (CASE)
