Ivory Data Access

The architecture of Ivory Data Access is designed for scalability and ease of management. The core components include the SQL Gateway, the Data Access Layer, and the Connection Manager. The SQL Gateway acts as the entry point, receiving SQL requests from clients.

It parses these requests and forwards them to the Data Access Layer. The Data Access Layer translates the generic SQL requests into database-specific queries. It supports various databases, including DB2, Oracle, and SQL Server.

The Connection Manager handles the creation, management, and pooling of database connections. Communication between components occurs over TCP/IP. The SQL Gateway and Data Access Layer can be deployed on the mainframe or a separate server, providing flexibility in deployment.

Configuration files are used to define database connections, security settings, and other operational parameters. The CLI provides administrative control, including starting, stopping, and monitoring the service. The system supports authentication methods such as user ID and password, and role-based access control (RBAC).

Comprehensive audit and logging capabilities are available for security and compliance. The system also supports ODBC and JDBC for client connectivity. The configuration files are typically text-based and can be edited to customize the behavior of Ivory Data Access.

For example, to configure a database connection, you would specify the database type, host, port, and credentials in the configuration file. The system's modular design allows for easy integration with existing systems and future scalability.
