,Lecture 1: Introduction
Object Oriented Programming (OOP): a way of programming that leverages the concept of classes and
objects. There are 4 paradigms of OOP:
• Abstraction: a process where you show only ‘relevant’ data and ‘hide’ unnecessary details
from the user.
o Example: on a DVD-player, the user only pushes the buttons on the outside (the
interface), while having no idea what is happening on the inside.
o Benefits: reduces complexity and isolates the impact of changes.
• Encapsulation: a practice that binds the data with the code that manipulates it and keeps the
data and the code safe from external interference. The grouping of related variables and
functions that operate on them into objects.
o Example: -
o Benefits: reduces complexity and increases reusability.
• Inheritance: the mechanism by which an object acquires some or all properties of another
object. It supports the concept of hierarchical classification.
o Example: -
o Benefits: eliminates redundant code.
• Polymorphism: a way to process objects differently based on their data type. In other words,
objects can have the same name for a method but the implementation may differ.
o Example: -
o Benefits: refactor ugly switch/case statements.
Business function: refers to an activity that a company performs, like order management, marketing,
selling, finances, product design, and so on. Business functions may be carried out by one or more
departments and may be organized hierarchically.
People speak different languages:
Business IT
KPI Functionality
Budget (cost) Use cases
ROI Release
Customer satisfaction Bugs
Usability Maintenance
Scalability
Budget (revenue)
Business process: the complete and coordinated set of collaborative activities that respond to a
business requirement for action and that deliver value to customers (e.g., the purchasing of a certain
product).
1
, Business process redesign (BPR): focuses on organizational effectiveness and efficiency.
Business process integration (BPI): “the techniques and mechanisms for managing the movement of
data, and the invocation of processes in the correct and proper order to support the management and
execution of common processes that exist in and between applications”.
Difference between BPI and BPR: BPI goes beyond organizational retooling of processes, aiming at:
• Integration of internal with external processes.
• Process models are used to specify cross-organizational process requirements.
Three integration waves:
Variable: property.
Function: method.
