refers to the process of
combining different individual systems,
subsystems, or components into a unified and
cohesive whole that functions seamlessly.
System Integration
is
regarded as a company that specializes in implementing,
planning, coordinating, scheduling, testing, improving and
sometimes maintaining IT systems
System Integrator
examples of SIs
Deloitte, IBM, Accenture, TCS
System Integration roles in different sectors
Information Technology (IT)
Manufacturing
Telecommunications
Automotive
Healthcare
Energy
Aerospace and Defense
Financial Service
Retail and ecommerce
Transportation and logistics
Education

SYSTEM INTEGRATION
METHODS
• Point-to-Point Integration
• Vertical Integration
• Star Integration
• Horizontal Integration
• Common Data Format integ
type of integration where
individual systems are connected directly to each other to
enable data exchange or communication.
Example: E-commerce
Point-to-Point Integration
the system components
(sub-systems) are integrated by creating functional “silos”,
beginning with the basic bottom function upward.
Example: Apple Inc. Hardware and Software
VERTICAL
INTEGRATION
system where each subsystem is connected with other sub-systems using
point-to-point connections.
STAR INTEGRATION
This method allows each sub-system to have just one single interface to communicate
with all the other sub-systems connected to the common interface layer (i.e., with ten
systems, there are only ten connections)
Example: Disney Acquisition
Horizontal Integration
Very often, this layer is referred to as an Enterprise Service Bus (ESB).
HORIZONTAL
involves
integrating different systems or applications that use
the same data format, making it easier to exchange
information.
Example : XML ( extensible markup language)

DATA INTEGRATION
BUSINESS-TO-BUSINESS INTEGRATION
LEGACY SYSTEM INTEGRATION
ELECTRONIC DOCUMENT INTERCHANGE (EDI)
ENTERPRISE APPLICATION INTEGRATION (EAI)
process of gathering data
from disparate sources (e.g., services, platforms,
and databases) together to provide businesses
with a centralized access point making data
more available and easy to process/consume by
systems and their users
DATA INTEGRATION
enables companies to automate business
communication and processes with all
stakeholders to exchange vital for their
business data more efficiently. So, with the
B2B integration, organizations facilitate realtime data exchange with their business
partners.
BUSINESS-TO-BUSINESS
INTEGRATION
implies connectivity between
outdated legacy systems (still
vital for core business) with
more modern IT infrastructure
to ensure seamless
communication between the
components and avoid
disrupting a company’s day-today workflow.
LEGACY SYSTEM
INTEGRATION
is the systemto-system exchange of business documents in a
standard electronic format between business
partners intended to replace paper-based
documents (e.g., invoices or purchase orders).
Hence, this type of integration is vital for
companies looking to enable paper-based
business transactions to save time and avoid
costly errors resulting from manual processing

all about bridging gaps between
different software programs and
applications (ERP, CRM, SCM, etc.)
to streamline business processes
through smooth data flow from one
point to another.

APPLICATION
INTEGRATION (EAI)
refers to the various approaches and strategies used to combined different software systems,componenys, or technologiea to work together effectively as a unified whole.

Communication
Patterns:
*Point-to-Point aintegration
*Hub-and-Spoke Integration
*Message-Oriented Middleware
*Event-Drivern Architecture
also known as direct integration
- where to specific software application or systems are directly connevted go each other for ghe purpose of exchanginv data or perfoing actions
