Data service integration

The "Data Service Integration" sample demonstrates how to create an integration that integrates with a relational database management system (RDBMS) and exposes employee information stored in the database as a REST API. To use this sample with Choreo, follow these steps:

Setting up the database

• Start a MySQL instance and create a database (for example, misampledb).
• Import the script to create the schema and populate employee data.
• Identify the publicly accessible connection URL and credentials for the database.

Create a MI Integration

• Login to Choreo console
• Select the iPaaS profile and create a new component named Integration as an API
• Provide a name and description for the component.
• Authorize and select the GitHub details
• Select the GitHub Account and the forked repository for GitHub Repository
• Select the Branch as main
• Select WSO2 MI as Build Preset
• Enter MIdata-serviceChoreo as the Project Path
• Enter MIdata-serviceChoreo/openapi.yaml as the OpenAPI File Path
• Click on "Create" to create the component.
• Once the component is created, go to the "Deploy" section and click on the "Deploy Manually" button.

Setting up Environment variables

• The database details need to be passed as environment variables.
• To do this, go to the DevOps portal and select the component and "Configs & Secrets" to configure the environment variables.
• Click on "Create" and select "Environment Variables" as the configuration type.
• Give a name for the Config Name
• Add key-value pairs to register them as environment variables. For example:
  • DB_DRIVER_CLASS for Key and com.mysql.jdbc.Driver for Value
  • DB_CONNECTION_URL for Key and jdbc:mysql://<public ip or hostname>:3306/misampledb for Value
  • DB_USER for Key and db username for Value
  • DB_PASS for Key and db password for Value
  • Click on Finish to apply the changes

Once done go to the Choreo Test console and use the Swagger console to try out the API
