What Is System Integration & Why It Matters 2021

Are you wondering what is system integration? This blog will provide you with all the information you need in order to understand system integration and its importance. 

What is System Integration? 

So, what is system integration? Well, system integration is the process of combining numerous discrete subsystems or sub-components into one larger system, allowing the subsystems to work together. In other words, the symbiosis generated through system integration helps the main system to achieve the organization's overarching functionality.

Most companies that use system integration want to improve their efficiency, and thus their productivity and quality of operations. The goal is usually to have the company's many IT systems communicate with one another in the background so that time and effort are not wasted manually sharing information with other departments/components of the organization, such as higher management. The organization will benefit from increased information flow speeds as well as lower operational expenses as a result of system integration.

System integration also connects the company to third parties like suppliers, consumers, and shareholders. Each of whom has a distinct interest in the data generated by your organization. Suppliers can maintain track of raw material levels, buyers may keep track of finished goods inventory, and shareholders can see the company's status at a glance in real time on a dashboard. All of these requirements can be easily satisfied with the help of system integration from a reputable systems integrator.

There Are 3 Different Forms of System Integration:

Integration administrations can be classified into three categories based on their use zone and type of use:

  • Enterprise Application Integration (EAI)
  • Data Integration (DI)
  • Electronic Document Integration/Interchange (EDI)

Enterprise Application Integration (EAI)

Enterprise Application Integration is a type of integration that relies on user input. It is an interaction that communicates with many administrations, gathers data, and then continues with further ways based on the desired activity or work process. With some assistance, the cycle might be started.

Data Integration (DI)

For the board announcing or any child of revealing, there are many information bases and administrations. Collecting and transforming information from various city services into focal points for smart announcing

When you need to combine your administrations into a single main access issue, you'll need information integration. For the most part, there are a lot of different information sources (or data sets) and you need them all combined in one place.

Electronic Document Integration/Interchange

EDI (Electronic Document Integration/Interchange) is a common form of business-to-business communication. Its capabilities are for the electronic exchange of reports and rules without the use of paper.

Importance of System Integration 

For some entrepreneurs, the benefits of system integration may be obvious. In any event, it's vital to have a complete understanding of the situation.

Higher Profit Margins

The fundamental advantage of system integration is that it greatly improves the efficiency of the company. Working with numerous systems and projects consumes a substantial amount of time, forcing reps to focus on time-consuming manual tasks rather than projects that are within reach.

Better Management & Examination

When a company has a lot of projects, it's difficult to figure out how it works. As a result, conducting multiple investigations for each program is not only time-consuming, but also frequently ineffective.

You can't look into such a test; you'll have to figure out a way to get a better perspective. It's nearly unimaginable with so many initiatives running at the same time.


The cost of maintaining diverse systems might be rather considerable. Each program necessitates some form of assistance, which can be provided at any time. Support and revamp planning can be time-consuming and costly. Hours spent on all-out assistance may outnumber the hours the entire system is operational.

Increased Customer Loyalty

System integration allows you to increase customer loyalty by reducing the amount of time you spend delivering your products and services. Working with many systems and projects, on the other hand, can take up a significant amount of time.

Methods of System Integration

What are the methods of system integration? Well, determining an effective systems integration solution is not an easy process by any stretch of the imagination. You must choose the right subsystems, the right locations, and the right relationship type. It is critical that you, as a company, fully comprehend the processes involved, as well as how they connect with all stakeholders and the business objectives. The systems integration will go well if you understand why and where the business requires operational harmony. 

Point-to-Point Integration is the First Method of System Integration.

In the strictest sense, point-to-point integration / connectivity is not system integration. Despite the systems' overall functionality, the complexity of the functions that can be performed is limited. These types of systems integration typically handle one business function at a time and are best suited to a 1:1 relationship. i.e. from one system to another. As the number of systems in use grows, so does the number of connections, and a point-to-point system integration quickly becomes unmanageable.

Vertical Integration

The structure that is established distinguishes vertical systems integration from other types of systems integration. Essentially, each sub-system is linked to the others based on how closely they are related in terms of the function they perform. This results in a "silo"-like structure, with the most basic function at the bottom and the remainder becoming increasingly complicated. This sort of system integration is straightforward and comprises a small number of systems; yet, this system integration paradigm can be rigid. Adding additional functionality creates its own ‘silo,' which makes things more difficult to maintain in the long run.

Star Integration

Simply put, a star integration is a collection of point-to-point system interconnections. To put it another way, a star connection is made up of a bigger number of simple connections. The more sub systems that are connected, the more points there are on the start and following lines in between.

Furthermore, when this system integration method connects each system to the remaining subsystems, the series of connections can at times resemble a star polyhedron. The actual system integration diagram will most likely resemble a plate of spaghetti (hence star integration is also known as spaghetti integration). In other words, if a corporation uses this strategy to approach system integration, the ideal neat and tidy IT architecture quickly becomes chaotic and impossible to map. Because, as you might expect, this provides significantly more capability than a single point-to-point connection, but managing the integrations becomes quite difficult.

Horizontal Integration is the Fourth Method of System Integration.

Horizontal integration is the process of integrating systems by leveraging a single specialized subsystem as a common user interface layer that connects all other subsystems. In other words, the number of connections required for system integration is minimized since the subsystems are connected indirectly through the main system rather than directly. There will only be five connections if there are five subsystems. There will only be ten connections if there are ten subsystems.

As a result, the key benefit of this strategy is the reduced number of connections required to maintain functioning, which decreases the amount of time, effort, and money spent on the system's development. An Enterprise Service Bus is the name for the intermediary layer or subsystem utilized in this type of system integration (ESB).
