• Suspendisse id sem consectetuer libero luctus adipiscing.

• This is a list item with two paragraphs.

  This is the second paragraph in the list item. You're only required to indent the first line. Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

• Another item in the same list.

• A list item with a blockquote:

  This is a blockquote inside a list item.

I strongly recommend against using any <blink> tags.

I wish SmartyPants used named entities like — instead of decimal-encoded entites like —.

Chapter 2

Phases of Software Development

1. Analysis
2. Design
3. Implementation

Analysis phase

Requirements -- what the customer wants or needs. Understanding on needs expressed by:

• Use cases can (can use UML)
• User manual style of analysis document

Design phase

Goals of OO design:

1. Identify classes -- things in the system
2. Identify responsibilities of the classes
3. Identify relationships between classes

Classes consist of:

1. Behavior: Methods represent the class behavior
2. State: Fields represent the state of the class instance (object)
3. Identity: each unique object should have its own address in memory which contains its state

Types of classes that are common:

1. Tangible things
2. Agents
3. Events and transactions
4. Users and roles
5. Systems
6. System interfaces and devices
7. Foundational classes

Types of class relationships:

1. Dependency (uses a)
2. Aggregation (has a)
   • Aggregation -- 1:many
   • Association -- 1:1
   • Composition -- "if I'm composed of other things, then I am considered responsible for the lifetime for those things"
3. Inheritance (is a)

Classes and relationships are the basis for a UML class diagram.
