Approaches

3 Approaches to System Integration

System integration is multifaceted and can be approached through different architectural models.

1
Point-to-Point (Star/Spaghetti)
Chaotic direct connections

Directly connects each system to all the other systems it needs to work with. Data is extracted from one system, processed, and sent to another. Each application performs all the necessary logic operations to translate, transform, and route data.

✓ Simple ✗ Not Scalable
Best for: Simple integrations, SaaS apps
2
Hub-and-Spoke Model
Central hub manages flow

Communication between all subsystems is managed by a central hub (message broker). The hub acts as a message-oriented software broker with a central integration engine to translate processes into a unified language and route messages to their correct destinations.

✓ Scalable ⚠ Bottleneck
Best for: E-commerce, finance, payment processing
3
Enterprise Service Bus (ESB)
Distributed bus architecture

Creates a separate, specialized subsystem — the ESB — that acts as a common interface layer connecting other subsystems. Each system is provided with its own integration engine and converter that translates messages into a standard format.

✓ Modular ✓ Flexible ✗ Complex
Best for: Large enterprises, EAI projects

APIs as a Method for Connecting Systems

There are many ways to connect separate systems, but Application Programming Interfaces (APIs) are the easiest and most direct way to link two systems and transfer data in a unified format.

Whether you're an online services company or a social media platform, OnWebApp creates external APIs to make it easy for customers to integrate with its products.

Why OnWebApp

Why Choose OnWebApp for System Integration?

Careful planning, effective project management, and expert expertise are essential for efficiently overcoming the challenges of systems integration.

1
System Compatibility

Different systems use different technologies, data formats, or protocols. We ensure effective communication through middleware, data transformation, and custom interfaces.

Connect any system Transform any format Bridge any protocol
2
Security & Compliance

Using different security protocols often leads to vulnerabilities. We rely on protocols that ensure data security and compliance with all relevant laws and regulations.

Enterprise-grade security GDPR/HIPAA compliant End-to-end encryption
3
Fewer Resources

Systems integration can be resource-intensive. We support building a comprehensive new platform that optimizes resource allocation.

Cost-effective Scalable Optimized allocation
4
Continuous Development

Systems integration often requires changes to business processes. We provide AI-powered products and platforms to analyze workflows and generate development proposals.

Process

OnWebApp System Integration Process

Companies can automate and gain full transparency of their business operations by joining enterprise data and systems together.

1
Planning and Feasibility Analysis

Every integration process starts with assessing systems to be integrated and mapping out a realistic strategy. Draw an accurate picture of your current software, define all integration requirements, determine scope, schedule, and cost. Include all possible risks and ways to handle them.

2
Architecture Modeling

Choose one of the common models (P2P, Hub-and-Spoke, ESB) or design a custom architecture. Create detailed blueprints of how systems will communicate. This is the most labor-intensive phase but of great importance as it outlines the integration model, methods, and process.

3
Implementation

The new integrated system is thoroughly tested to ensure all modules seamlessly interact without losing data during transmission. Keep the implementation stage short to avoid challenges. Agile project management can be applied to adjust to the changing landscape.

4
Maintenance

Schedule performance diagnostics to make sure all modules function flawlessly and no errors occur. Routine maintenance ensures long-term reliability and optimal performance of the integrated systems.

What is the Role of OnWebApp in Systems Integration?

You may have the best integration technologies, but without human expertise, they won't provide much value. Instead of designing and implementing your integration project yourself, you can rely on the services of OnWebApp's systems integrators.

Our systems integrators help clients connect disparate computer subsystems from different vendors, ensuring these subsystems operate seamlessly. We perform planning, organizing, testing, and maintaining computer operations.

The most important advantage of having our systems integrators is the expertise and resources they provide. Among the most prominent licenses we have obtained are those of IBM and Oracle.
