Benefits of Using DreamFactory for Legacy Systems
DreamFactory streamlines the modernization of legacy systems, offering three key benefits: automated API generation, tools for developing modern interfaces, and significant reductions in development time and costs.
Automatic API Generation for Legacy Databases
DreamFactory simplifies API creation for over 18 databases, including SQL Server, Oracle, and IBM DB2, in just minutes. By entering database credentials, it analyzes the schema and generates CRUD endpoints, complete with interactive OpenAPI (Swagger) documentation. This feature allows developers to test endpoints instantly without writing any code.
"By embracing this automated approach, development teams can shave weeks if not months off the development cycle, and in doing so greatly reduce the likelihood of bugs or security issues due to mishaps such as SQL injection." - DreamFactory Documentation
In addition to speed, DreamFactory enhances security with enterprise-grade features like Role-Based Access Control (RBAC) and API key management. These tools allow you to set precise roles and limit database access, ensuring that only authorized operations are performed.
Creating Modern Interfaces for Legacy Systems
DreamFactory doesn't just stop at API generation - it also enables the creation of modern web and mobile interfaces on top of existing legacy systems. This eliminates the need for a full system overhaul. For example, in 2024, Adalo utilized DreamFactory to integrate a MySQL Employees database into a mobile directory app. By leveraging "External Collections", they enabled read-only operations seamlessly.
The platform also supports virtual fields, which allow you to transform or merge data without altering the original schema. For instance, you can combine first and last names into a full name or reformat dates to match modern standards.
Reducing Development Time and Costs
Manually building APIs can be a time sink. DreamFactory automates this process, cutting development time drastically. It even converts legacy SOAP services into REST interfaces without requiring any changes to the original code. This feature ensures compatibility with no-code tools like Adalo Blue, making integration smooth and efficient.
"The cost of developing an API layer for each system could cost thousands of developer hours... DreamFactory's API integration has lifted a large cost of software development off your plate!" - Terence Bennett, CEO, DreamFactory
DreamFactory also supports database transactions via a user-friendly interface. By appending rollback=true to an API call URI, you can ensure a complete rollback if a multi-table transaction fails, preventing orphaned records in your legacy database. This built-in data integrity eliminates the need for custom coding, saving even more time and resources.
How to Set Up DreamFactory for Legacy Integration
DreamFactory Legacy System Integration Setup Process in 3 Steps
DreamFactory makes it easier to connect legacy systems to modern applications by generating APIs quickly. Here's how to install and configure the platform for this purpose. The process involves three key steps: installing DreamFactory, connecting your databases, and converting outdated SOAP services into REST APIs.
Installing and Configuring DreamFactory
DreamFactory provides several installation options tailored for different environments. Whether you're setting up for production, testing, or cloud deployment, there's a method that fits:
- GitHub: Ideal for custom production setups.
- Automated Linux installers: Great for quick and straightforward deployments.
- Docker containers and Bitnami packages: Useful for testing environments.
- Cloud images: Available for AWS, Azure, and Google Cloud.
For production environments, the GitHub method offers the most control. Here’s a quick walkthrough:
-
Clone the repository:
git clone https://github.com/dreamfactorysoftware/dreamfactory.git -
Install dependencies:
composer install --no-dev -
Configure your environment:
php artisan df:env
(Choose your system database and add credentials.) -
Complete the setup:
php artisan df:setup
(This runs migrations, seeds data, and creates your first admin user.) -
Ensure the
storage/andbootstrap/cache/directories are writable by your web server.
For Linux systems like Ubuntu, Debian, or CentOS, the dfsetup.run script simplifies installation. It automates dependency setup, web server configuration, and core installation. Just make sure your server meets the requirements: PHP 8.1 or higher, a web server (Nginx or Apache), and at least 4GB of RAM - or 8GB if the system database is hosted on the same machine.
Connecting Legacy Databases and Systems
After installation, linking legacy databases is a straightforward process. This step highlights DreamFactory's role as a bridge between older data sources and modern applications. Through the Services tab in the administration console, enter the credentials for your legacy system - whether it's Microsoft SQL Server, Oracle, or SAP SQL Anywhere. DreamFactory will analyze the schema and instantly generate REST endpoints for CRUD operations and stored procedures.
The platform supports more than 18 database types, including older systems like Firebird. Once connected, you can immediately test the API endpoints. To maintain security, always use Role-Based Access Control (RBAC) to limit API keys to specific tables or stored procedures rather than granting full database access.
Converting SOAP to REST APIs
Many legacy systems still use SOAP services, which can be difficult to integrate with modern platforms. DreamFactory's Remote SOAP Connector solves this by converting SOAP services into REST APIs without requiring changes to the original SOAP code.
"DreamFactory... can convert SOAP services into REST with no refactoring required to the SOAP code." - DreamFactory Documentation
To perform the conversion, go to the Services tab, select Remote Service, and choose SOAP Service. Enter the SOAP service's WSDL (Web Services Description Language), and DreamFactory will map SOAP actions to REST endpoints. It also generates OpenAPI documentation, making it easy to test endpoints and confirm they trigger the correct SOAP actions.
If the SOAP response needs adjustments to work with modern front-ends, you can use DreamFactory's server-side scripting to transform the responses before they reach the client. This functionality ensures that legacy data integrates smoothly with mobile apps, web applications, and no-code platforms like Adalo Blue. By creating RESTful services from SOAP interfaces, DreamFactory enables seamless integration with today’s no-code tools.
DreamFactory and No-Code Platform Integration Examples
DreamFactory simplifies the process of integrating legacy data into modern enterprise applications, thanks to its API automation capabilities. Older systems often contain critical data but lack the interfaces needed for modern app interactions. DreamFactory bridges this divide by creating REST APIs, enabling no-code platforms to access and utilize legacy data seamlessly.
Connecting Legacy ERPs to Modern Applications
Legacy ERP systems often store essential business data but were never designed to connect with today's apps. DreamFactory solves this challenge by generating REST APIs for databases like SQL Server, Oracle, and IBM DB2 - databases that underpin many ERP systems.
Instead of replacing legacy systems entirely, organizations can use DreamFactory to expose specific data through APIs. This allows modern applications to retrieve the necessary information without disrupting the existing infrastructure.
"Legacy systems make up 31% of the technology in organizations. These are systems that might still provide value for your enterprise but are unable to interact with other software tools." - Terence Bennett, CEO, DreamFactory
To make this integration secure and efficient, DreamFactory uses API keys for authentication, passed via the X-DreamFactory-API-Key header. This approach is particularly helpful when working with complex ERP systems. Beyond ERPs, DreamFactory also pairs effectively with platforms like Adalo Blue to elevate enterprise app development.
Using DreamFactory with Adalo Blue for Enterprises
Adalo Blue integrates DreamFactory's API generation with a visual app builder tailored for enterprise needs. This combination allows businesses to develop internal tools - such as directories, inventory management systems, or customer portals - that pull data directly from legacy systems, eliminating the need for custom backend coding.
The integration is straightforward. Adalo's External Collections feature uses DreamFactory as the backend API provider, while Adalo serves as the user-friendly frontend interface. Teams only need the API Base URL and API Key from their DreamFactory instance to configure the connection.
DreamFactory excels at handling large-scale, interconnected datasets. For instance, the MySQL Employees sample database, containing about 4 million related records, would typically require significant backend development to make it accessible via a mobile app. With DreamFactory and Adalo Blue, teams can build functional apps in a fraction of the time - days or weeks instead of months - while maintaining enterprise-level security with features like SSO, advanced permissions, and encrypted connections.
Even older systems running on SOAP services are not left out. DreamFactory can transform these outdated protocols into REST APIs that Adalo can utilize. This means legacy systems without modern APIs can still power mobile applications, extending their lifespan and delivering the modern interfaces users expect.
Security Best Practices for Legacy Integrations with DreamFactory
Integrating legacy systems comes with its own set of security challenges, making it crucial to implement strong safeguards. DreamFactory offers several layers of protection to keep sensitive data secure during the integration process. With legacy data now exposed via APIs, securing these connections is a top priority. Here’s how DreamFactory’s robust API management features can help.
Implementing Role-Based Access Control (RBAC)
DreamFactory uses a structured permission system that starts with API Keys and flows through Roles, Services, Components, and HTTP methods. Instead of relying on a single API key for all access, you should create specific roles tailored to each integration. As highlighted in the DreamFactory Environment Security Guide:
"Never use a blanket API key for your APIs! Instead, create roles which expressly define the level of privileges intended to be exposed via the API." - DreamFactory Environment Security Guide
For instance, a mobile inventory app might only need read access to product data, while a warehouse management system could require full CRUD permissions. Permissions can be fine-tuned down to individual database tables using component paths like _table/employees/*. DreamFactory also supports record-level security through precise server-side filters. When connecting to legacy SQL databases, ensure the database account used has only the minimum privileges required - DreamFactory will inherit these restrictions automatically.
Managing API Keys and Securing Endpoints
Each application should use a unique X-DreamFactory-API-Key, ensuring that master credentials for legacy systems remain hidden from client applications. DreamFactory secures connection strings using AES-256 encryption, decrypting them only during active connections.
"DreamFactory functions as a secure proxy that creates REST API services, provides server-side scripting, and enforces role-based access control." - DreamFactory Security Guide
In production environments, disable debugging by setting APP_DEBUG to false and APP_ENV to production in the .env file. This prevents sensitive error messages from being exposed. Always use HTTPS with SSL certificates to encrypt traffic - services like Let's Encrypt make this setup straightforward. Configure CORS settings to restrict API access to trusted domains, blocking unauthorized cross-site requests. DreamFactory’s admin console also provides instant control over security, allowing you to deactivate users, roles, or apps, which immediately invalidates associated session tokens and API keys - an essential feature for incident response.
Adding Multi-Factor Authentication (MFA) and Encryption
To strengthen endpoint security, consider adding additional authentication measures. While DreamFactory doesn’t include built-in MFA, it integrates seamlessly with enterprise identity providers like Okta, Auth0, AWS Cognito, and Azure Active Directory. These providers handle multi-factor authentication using protocols such as SAML 2.0, OpenID Connect, and OAuth 2.0. For legacy systems with sensitive data, enforce user-based authentication via an SSO provider rather than relying on anonymous API key access.
DreamFactory issues a JWT through the X-DreamFactory-Session-Token, with configurable expiration times to limit token exposure. All communication between DreamFactory and clients should be encrypted using SSL/TLS. For legacy LDAP integrations, DreamFactory supports LDAPS (LDAP over SSL) on port 636, ensuring directory queries are encrypted. Additionally, database credentials are decrypted only during active connections and are never stored in plaintext. This ensures that even if the DreamFactory server is compromised, passwords for legacy systems remain secure.
Conclusion
DreamFactory tackles a major hurdle for modern businesses: updating systems without abandoning critical legacy infrastructure. Instead of opting for expensive, disruptive migrations, it introduces a secure API layer that connects legacy databases and SOAP services to modern applications - no backend coding required.
Legacy systems still play a crucial role in enterprise technology stacks. DreamFactory maximizes the value of these systems by wrapping them in REST APIs that integrate effortlessly with cloud platforms, mobile apps, and no-code tools like Adalo Blue.
