Prerequisites and Setup Requirements

Before connecting SAP HANA's OData Connector, it's crucial to configure your environment to meet technical standards, particularly those specific to the U.S. This ensures your setup is ready for system configuration and can perform efficiently.

System Requirements and Configuration

DreamFactory, built on the Laravel Framework with PHP, is compatible with most hosting environments. However, your server must meet specific baseline requirements to ensure smooth operation.

Hardware: A 64-bit server with at least 4GB of RAM (8GB is recommended if hosting the system database).

Software: PHP 8.1 or newer, Apache or NGINX as the web server, a supported database (MySQL/MariaDB, PostgreSQL, SQLite, or MS SQL Server), and the necessary PHP extensions with installation permissions.

For cloud deployments, the following minimum server configurations are recommended:

Although DreamFactory can be hosted on Windows Server with IIS, using a Linux distribution like Ubuntu, Debian, or CentOS is strongly recommended for better performance, especially when utilizing automated installers.

U.S. Format Configuration

To align with U.S. formatting standards, configure DreamFactory to use the MM/DD/YYYY date format, display currency as $1,234.56, and apply commas for thousand separators with periods for decimals. These formats can be enforced consistently using database functions or PHP-scripted services.

For instance, you can adjust date field formats by leveraging database functions like Oracle's TO_DATE() within the Schema tab by adding the function to a field's DB Function Use setting.

For more extensive format adjustments, create a PHP script as a scripted service. This script can iterate through all tables and fields, applying the appropriate date formatting function (e.g., TO_DATE({value}, 'DD-MON-YY HH.MI.SS AM')) to fields with a date data type. Once these configurations are in place, you'll be ready to secure your connection.

Security Setup

DreamFactory ensures secure SAP HANA connections by encrypting credentials, enforcing Role-Based Access Controls (RBAC), and managing sessions through JSON Web Tokens (JWT). The platform enhances the security measures of connected databases while safeguarding sensitive information.

Credential encryption protects master credentials, including connection strings, usernames, and passwords, ensuring client applications cannot directly access these details. RBAC allows you to control which components are visible to specific users and restricts HTTP methods to only those necessary for each role.

To prevent cross-site scripting attacks, DreamFactory enforces CORS. It also supports various authentication methods, such as OAuth providers, LDAP, and Active Directory, while deconstructing query filter strings to reduce the risk of SQL injection. Server-side scripting adds another layer of protection by enabling custom security measures and notifications.

Always use HTTPS for transactions and keep the system updated with the latest patches. Utilize DreamFactory's logging and reporting tools to monitor API activity and data access, ensuring your SAP HANA integration remains secure against potential threats.

Step-by-Step Connection Guide

Once you've set up the environment and ensured security measures are in place, it's time to connect SAP HANA's OData Connector with DreamFactory. By following these steps, you'll establish a secure and efficient bridge between SAP HANA and your applications through DreamFactory.

Enable HTTP and HTTPS endpoints to allow external access.

Set up user permissions to restrict access, ensuring only the necessary schemas and tables are exposed.

Test your OData endpoints to confirm they’re functioning correctly. For example, try opening a URL like this in your browser:

https://your-hana-server:port/sap/odata/sap/SERVICE_NAME/$metadata

Once you’ve verified that the OData service is active, you’re ready to connect it to DreamFactory.

Connect DreamFactory to SAP HANA

Log into the DreamFactory admin interface and navigate to the API Generation & Connections section. Under the API Types submenu, select the Database dropdown and click the + button to create a new API. From the available options, choose SAP HANA OData Connector service type.

Here’s how to configure your connection:

Assign a clear, descriptive name (e.g., "HANA_Sales_Data").

Enter your connection details, including the host name (using its fully qualified domain name), username, password, and database name.

Specify the connection string, including the port number for your HANA instance. For single-container systems, this is typically 30015, while multi-tenant systems use a format like 3NN15, where NN represents the instance number.

Adjust additional settings such as driver options, the appropriate U.S. time zone (Eastern, Central, Mountain, or Pacific), and caching preferences.

Once everything is set, click Save to establish the connection. DreamFactory will now generate the REST API for your SAP HANA data.

Generate APIs Automatically

DreamFactory simplifies the process of turning your SAP HANA data into RESTful APIs. Once the connection is saved, the platform automatically creates REST endpoints for every accessible table, view, and stored procedure. These endpoints support standard HTTP methods:

GET: Retrieve data.

POST: Create new records.

PUT: Update existing records.

DELETE: Remove records.

DreamFactory also generates interactive API documentation, which includes sample requests, responses, parameter descriptions, and authentication details. You can access this documentation via the API Docs tab. To secure your APIs, configure role-based access controls by defining specific roles and permitted HTTP methods.

"DreamFactory streamlines everything and makes it easy to concentrate on building your front end application. I had found something that just click, click, click... connect, and you are good to go." - Edo Williams, Lead Software Engineer, Intel

Finally, test your APIs using built-in tools or platforms like Postman. Ensure that data is being returned correctly and that all security measures are functioning as intended. Once these tests are successful, your SAP HANA integration is ready for production, allowing seamless access to enterprise data for any application or service.

API Management and Customization

DreamFactory offers tools that go beyond auto-generated endpoints, enabling you to adapt your APIs to meet specific enterprise needs. These features are particularly useful for aligning with U.S. business standards and compliance requirements, ensuring your APIs are both functional and secure.

Custom API Logic with Server-Side Scripts

DreamFactory’s scripting engine allows you to customize API responses without altering the underlying SAP HANA data. It supports several scripting languages, including V8Js, Node.js, PHP, and Python.

Using server-side scripts, you can pre-process and post-process API requests to format data according to U.S. standards or filter out sensitive information. For instance, scripts can merge fields - like combining first and last names into a single display name - or perform calculations, such as applying state-specific tax rates. Additionally, sensitive data fields can be excluded from API responses, ensuring compliance with privacy regulations.

Scripts also enable more advanced workflows by triggering additional API requests. For example, when retrieving customer data from SAP HANA, a script can automatically fetch credit scores from a third-party financial service and include that information in the API response. This functionality makes it easy to enrich data and streamline complex operations.

DreamFactory also supports direct integration of database functions into API responses. For example, you can apply Oracle's TO_DATE() function to reformat dates like this: TO_DATE({value}, 'DD-MON-YY HH.MI.SS AM'). This level of customization ensures your APIs meet specific business and compliance needs.

All customizations are seamlessly integrated into the API documentation generated by DreamFactory.

Auto-Generated API Documentation

DreamFactory automatically generates detailed Swagger/OpenAPI documentation for all your SAP HANA APIs. This documentation includes sample requests and responses, parameter descriptions, authentication details, and more, making it easier for developers to understand and work with your APIs. It adheres to industry standards but can also be tailored to include company-specific details, usage guidelines, and notes on U.S. compliance requirements.

Each API endpoint is clearly documented with supported HTTP methods, required parameters, and expected response formats. This reduces onboarding time for new developers and ensures consistent API usage across your organization. The interactive documentation even allows developers to test API calls directly from their browser, eliminating the need for separate testing tools during the development phase. Response examples reflect actual data structures, giving developers a clear understanding of what to expect when working with your SAP HANA data.

API Monitoring and Logging

Maintaining API reliability and meeting regulatory requirements are critical in enterprise environments. DreamFactory offers extensive logging and monitoring tools to help you achieve both.

The platform logs key details of API requests, including user IDs, timestamps, endpoint paths, request and response data, source IP addresses, and HTTP status codes. This information supports compliance with major U.S. regulations, as summarized below:

Role-Based Access Control (RBAC) complements these logging capabilities by allowing you to assign users to predefined roles with specific permissions. Adrian Machado, an engineer, highlights its benefits:

"Role-Based Access Control (RBAC) simplifies API permission management by assigning users to predefined roles, each with specific permissions".

This ensures sensitive SAP HANA data is accessed only by authorized users, with all actions carefully audited.

DreamFactory also allows you to configure API limits at various levels - user, role, instance, or endpoint. This helps protect against attacks and manage data access costs.
