According to the SAP HANA SQLScript Reference, the following statements can be used when implementing transaction management logic in SQLScript using savepoints:

• Savepoint: Creates a savepoint with a specified name within the current transaction. A savepoint marks a point in the transaction that can be rolled back to without affecting the rest of the transaction. For example, SAVEPOINT sp1;
• Rollback to savepoint: Rolls back the current transaction to the specified savepoint. All changes made after the savepoint are undone, but the transaction remains active. For example, ROLLBACK TO SAVEPOINT sp1;
• Release savepoint: Releases the specified savepoint and all subsequent savepoints. The released savepoints are no longer valid and cannot be rolled back to. For example, RELEASE SAVEPOINT sp1;

The other options are incorrect, because:

• Reverse savepoint is not a valid statement in SQLScript. There is no such statement in the SAP HANA SQLScript Reference.
• Alter system savepoint is not a statement that can be used in SQLScript, but a statement that can be used in SQL. It triggers a savepoint operation for the entire database system, not for a specific transaction. It is used for administrative purposes, such as backup and recovery, not for transaction management logic.

 To consume a Node.js service in an SAPUI5 application, you need to define the variable for the exposed service in the requires section of the HTML5 module in the mta.xml file. This way, you can specify the dependency of the SAPUI5 application on the Node.js service and bind them together. The requires section allows you to reference a resource or a module that provides a service or a capability that your module needs. You can also define additional properties and parameters for the required element, such as the name of the variable that holds the service URL. References: The MTA Development Descriptor, The MTA Deployment Descriptor, Developing Multi-Target Applications

SAPUI5 is a JavaScript-based UI framework that enables the development of web applications that run on various devices and platforms. SAPUI5 has the following characteristics12:

• Provides an extensibility concept: SAPUI5 allows developers to extend or customize the standard UI components, such as controls, views, or controllers, to meet specific requirements or scenarios. SAPUI5 also supports the creation of custom UI components, which are reusable and modular UI elements that can be integrated into other SAPUI5 applications.
• Enables responsive application design: SAPUI5 supports the development of responsive applications, which are applications that adapt to different screen sizes, orientations, and resolutions, and provide a consistent and optimal user experience across different devices. SAPUI5 provides various layout options, such as grids, panels, or flexboxes, to arrange the UI elements according to the available space. SAPUI5 also provides various UI patterns, such as master-detail, split-screen, or full-screen, to organize the application content and navigation according to the device type.
• Supports customer-specific theming: SAPUI5 allows developers to apply different themes to the UI components, such as colors, fonts, icons, or backgrounds, to match the branding or style of the customer or the application. SAPUI5 provides a set of predefined themes, such as SAP Fiori, SAP Belize, or SAP Quartz, that follow the SAP design guidelines and principles. SAPUI5 also provides tools, such as the UI Theme Designer or the SAPUI5 Theme Builder, to create or modify custom themes.

The other options are not correct because they are not characteristics of SAPUI5. SAPUI5 does not render the UI on the server side, but rather on the client side, in the browser or the device that accesses the application. SAPUI5 does not provide a device-specific user experience, but rather a device-agnostic user experience, which means that the application can run on any device and platform without requiring any changes or adaptations. References:
