 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

To exclusively use declarative logic in an SQL Script procedure, you can use TABLE variables and MAP_REDUCE functions. TABLE variables are variables that store intermediate results of SQL queries in a tabular format. You can use TABLE variables to define data transformations and data flows without using imperative statements or side effects1. MAP_REDUCE functions are functions that apply a map function to each row of a table and then aggregate the results using a reduce function. You can use MAP_REDUCE functions to implement complex algorithms and calculations in a declarative way2.

The other two options, COMMIT statement and IF condition, are not operators that can be used to exclusively use declarative logic in an SQL Script procedure. COMMIT statement is a statement that ends a transaction and makes all changes permanent in the database. You cannot use COMMIT statement in a declarative logic, as it is an imperative statement that has a side effect3. IF condition is a condition that executes a block of code based on a boolean expression. You cannot use IF condition in a declarative logic, as it is an imperative construct that introduces control flow4. References: 1: TABLE Variables | SAP Help Portal 2: MAP_REDUCE Function | SAP Help Portal 3: COMMIT Statement | SAP Help Portal 4: IF Statement | SAP Help Portal

SAP HANA calculation views are flexible information views that you can use to define more advanced slices on the data available in the SAP HANA database. Calculation views can be created using graphical or script-based editors, and can include any combination of tables, column views, attribute views, analytic views, and other calculation views. Calculation views can also support complex expressions, multidimensional analysis, currency conversion, hierarchies, and other analytic capabilities. Some general characteristics of calculation views are:

• Need database tables to execute. Calculation views are based on the data stored in the SAP HANA database tables, either in column or row format. Calculation views can access data from local or remote tables, as well as virtual tables that are mapped to external data sources. Calculation views can also use data from other information views, such as attribute views or analytic views, which are also based on database tables. Calculation views do not store any data themselves, but rather perform calculations on the fly when queried.
• Do NOT need an application server to execute. Calculation views are executed by the SAP HANA Calculation Engine, which is a component of the SAP HANA database that handles the processing of complex calculations and transformations on the data. Calculation views do not require any application server or middleware layer to run, as they are directly exposed to the reporting tools and applications via SQL or MDX interfaces. Calculation views can also be accessed by SAP HANA extended application services, advanced model (XS advanced), which is a framework for developing and running applications on the SAP HANA platform.

The other options are incorrect because calculation views do not need an application server to execute, nor do they not need database tables to execute. These are the opposite of the correct characteristics of calculation views. References:
