It performs integrated solutions over the internet, offering a flexible and cost-effective way to build a centralized hub.
Businesses often use cloud-based integration in marketing automation, inventory management, and retail operations to enhance data flow and create a cloud-centric IT landscape. With this process, you can handle increased data volumes while following the competitive market closely.
API-based integration
Application programming interface-based integration involves using APIs to connect different software applications, services, and systems. An API acts as an interface that allows applications to communicate and share data in a controlled manner. This integration fosters data exchange and functionality between diverse technologies.
You can use API-based integration in mobile app development, social media platforms for payment gateways, and email marketing services that offer analytics tools and customer support.
Different system integration methods
System integrations vary depending on your approach and the technology used to connect systems and applications. Organizations may use a combination of integrations to meet specific project requirements, update existing IT infrastructure, and reduce complexities in their overall operations.
Explore the different system integration methods below.
Point-to-point integration
In point-to-point integration, applications are connected directly using custom code. Each integration is created and maintained separately for every pair of applications that require communication.
This integration becomes complex and challenging to manage as system connections increase.
Horizontal integration
This integration is a company's business strategy to expand its operations by merging with other companies in the same industry. Horizontal integration strengthens a business’ position within the industry and increases market share by bringing together similar firms under a single umbrella.
Some benefits of this integration include reduced competition, market expansion to reach new customers, and cross-selling opportunities for combined development efforts.
Vertical integration
Vertical integration is the opposite of the horizontal method as it focuses on companies that merge with other businesses at different stages of the supply chain. The company seeks to control multiple stages of production, distribution, and retailing processes when building better relationships with suppliers or customers.
The key features of vertical integration include cost control, quality assurance, and improved market power, all of which contribute to a competitive advantage.
Common data format integration
Common data format integration uses a standardized approach to integrate different software and applications. Data is mapped and transformed into a predefined format, a functional component that allows data exchange and communication between disparate systems. In turn, systems meant to operate independently can now function as a cohesive unit.
You can implement integration using standard data forms like XML (eXtensible Markup Language) or JSON (JavaScript Object Notation). The choice depends on industry standards, data complexity, and application requirements.
What are the steps of system integration?
System integration involves several key steps to connect software applications, systems, and technologies successfully. You must follow every stage, including consistently monitoring and maintaining your processes, to ensure the business integrates efficiently without causing long-term problems.
