Study Notes
Key Roles in Software Development
- Users: Individuals who utilize software, aiming for enjoyment or recognition in their tasks.
- Customers (Clients): Decision-makers for software procurement, who may or may not be users themselves.
- Software Developers: Professionals responsible for creating and maintaining software, often titled software engineers.
- Development Managers: Leaders of the software development organization, overseeing project execution.
Software Development Life Cycle (SDLC)
- Definition: A structured methodology encompassing processes for high-quality software creation.
-
Phases of SDLC:
- Requirement analysis: Identifying needs and expectations.
- Planning: Developing a roadmap for project execution.
- Software design: Architectural design to guide development.
- Software development: Actual coding of the software.
- Testing: Validating functionality and reliability.
- Deployment/Maintenance: Releasing the software and ensuring ongoing support.
Object-Oriented Conceptual Framework
-
Object Model Elements:
- Abstraction: Distills an object's essential characteristics, differentiating it from other objects, focusing on external behavior rather than implementation.
- Encapsulation: Bundles data and methods into a single unit (class), while restricting access to certain components to protect the object's internal state.
- Modularity: Divides a program into separate, manageable modules that can be developed independently but still interact with each other, reducing overall costs.
- Hierarchy: Establishes a ranking system for abstractions, primarily reflected in class structures (is a hierarchy) and object structures (part of hierarchy).
Hierarchy in Object Models
- Single Inheritance: A hierarchy where a subclass inherits from one superclass.
- Multiple Inheritance: A hierarchy where a subclass inherits from multiple superclasses, potentially leading to naming conflicts or structural ambiguities.
- Inheritance Lattice: A diamond-shaped inheritance structure that can arise from repeated inheritance, questioning whether derived classes have one or multiple copies of a shared superclass's attributes.
Aggregation
- Represents a part-of relationship, illustrating how components fit into the overall system hierarchy.
