NO.44 Which OData capacity do you use when you need to restrict the number or selection of exposed columns?
Please choose the correct answer.

Parameter entity sets

Key specification

Property projection

Property projection is an OData capability that allows you to restrict the number or selection of exposed columns in an OData service. Property projection is achieved by using the $select query option, which specifies a subset of properties to be included in the response. The $select query option can be applied to a single entity, a collection of entities, or a complex type. Property projection can be used to reduce the payload size and improve the performance of the OData service.
For example, suppose you have an OData service that exposes a Products entity set with the following properties: ID, Name, Category, Price, and Description. If you want to restrict the number or selection of exposed columns to only ID and Name, you can use the $select query option as follows:
GET /Products?$select=ID,Name
The result is: { “@odata.context”: “$metadata#Products(ID,Name)”, “value”: [ { “ID”: 1, “Name”: “Laptop” }, { “ID”: 2, “Name”: “Mouse” }, { “ID”: 3, “Name”: “Keyboard” } ] }
The following OData capabilities are not used to restrict the number or selection of exposed columns, but for other purposes:
* Parameter entity sets: Parameter entity sets are a way to define entity sets that require one or more parameters to be specified in the request. Parameter entity sets can be used to implement function imports or actions that return a collection of entities. Parameter entity sets can also be used to filter or sort the results based on the parameters.
* Aggregation: Aggregation is a way to apply aggregate functions, such as sum, count, min, max, or average, to the properties of an entity set or a complex type. Aggregation can be used to perform calculations or analysis on the data. Aggregation is achieved by using the $apply query option, which specifies a transformation pipeline with various operators, such as groupby, aggregate, filter, or order by.
* Key specification: Key specification is a way to define the key properties of an entity type, which uniquely identify an entity instance within an entity set. Key specification is part of the entity type definition in the metadata document of the OData service. Key specification can be used to retrieve a single entity by its key values.

SAP HANA database version

Project name

Template

Namespace

When you create a new project in SAP Web IDE for SAP HANA, you must specify the project name and the template. The project name is a unique identifier for your project that is used to create the folder structure and the deployment descriptor file (mta.yaml) for your project. The template is a predefined set of files and configurations that provide the basic structure and functionality for your project. You can choose from various templates, such as SAP HANA Database Project, SAP Cloud Platform Business Application, SAP Fiori Freestyle Project, and more, depending on your development scenario and requirements.
The following information is not required or not applicable when you create a new project in SAP Web IDE for SAP HANA:
* SAP HANA database version: This information is not required when you create a new project in SAP Web IDE for SAP HANA, as the SAP HANA database version is determined by the target environment where you deploy your project. The SAP Web IDE for SAP HANA supports multiple SAP HANA versions, such as SAP HANA 2.0 SPS 04, SAP HANA 2.0 SPS 05, and SAP HANA Cloud. You can check the compatibility of the SAP Web IDE for SAP HANA and the SAP HANA database versions in the SAP HANA Deployment Infrastructure Reference.
* Namespace: This information is not applicable when you create a new project in SAP Web IDE for SAP HANA, as the namespace is a concept that is used to organize the design-time artifacts in the SAP HANA repository, which is a legacy feature that has been deprecated since SAP HANA 2.0 SPS 02.
Instead of using the SAP HANA repository, you should use the SAP HANA Deployment Infrastructure (HDI) to deploy your database artifacts to HDI containers, which are isolated schemas that represent
* runtime objects. You can configure the artifact namespaces for your HDI containers by editing the
.hdiconfig file in the db module of your project.

NO.58 What are the issue categories that SQL Script Code Analyser scans for? There are 3 correct answers to this question.

Performance

Privileges

Security

Business logic

Consistency

The SQL Script Code Analyser is a tool that scans SQL Script code for potential issues and provides suggestions for improvement. The tool can be accessed from the SAP Web IDE for SAP HANA or from the SAP HANA database explorer. The tool scans for issues in the following categories:
* Performance: This category covers issues that may affect the execution time or resource consumption of the SQL Script code, such as inefficient joins, missing indexes, unnecessary data transfers, etc. The tool provides recommendations for optimizing the code, such as using parallel processing, avoiding nested loops, using table variables, etc.
* Security: This category covers issues that may expose the SQL Script code to security risks, such as SQL injection, privilege escalation, data leakage, etc. The tool provides recommendations for securing the code, such as using parameterized queries, escaping literals, applying proper authorization checks, etc.
* Consistency: This category covers issues that may affect the readability, maintainability, or portability of the SQL Script code, such as coding style, naming conventions, documentation, compatibility, etc.
* The tool provides recommendations for improving the code quality, such as using consistent indentation, avoiding hard-coded values, adding comments, following best practices, etc.
The other options are incorrect because privileges and business logic are not issue categories that the SQL Script Code Analyser scans for. Privileges are handled by the SAP HANA Deployment Infrastructure framework, which automatically grants the necessary privileges to the technical users and roles that access the HDI container objects. Business logic is the domain-specific logic that defines the functionality and behavior of the SQL Script code, and it is not within the scope of the tool to verify or validate it. References:

Dynamic tiering

Text analytics

Multi-core and parallelization

System replication

Columnar OLTP and OLAP

SAP HANA, express edition is a streamlined version of SAP HANA that can run on laptops and other resource-constrained hosts, such as a cloud-hosted virtual machine. SAP HANA, express edition is free to use for in-memory databases up to 32 GB of RAM. SAP HANA, express edition supports the following services:
* Text analytics: This service allows you to analyze unstructured text data, such as documents, emails, tweets, and blogs, using natural language processing techniques. You can use text analytics to extract entities, facts, sentiments, and keywords from text data, and to perform linguistic analysis, such as tokenization, lemmatization, and part-of-speech tagging.
* Multi-core and parallelization: This service allows you to leverage the multi-core architecture and parallel processing capabilities of SAP HANA to optimize the performance of data-intensive operations, such as queries, calculations, and transformations. You can use multi-core and parallelization to distribute the workload across multiple CPU cores and threads, and to execute tasks in parallel or in batches.
* Columnar OLTP and OLAP: This service allows you to store and process data in a columnar format, which enables faster data compression, aggregation, and analysis. You can use columnar OLTP and OLAP to support both transactional and analytical workloads on the same data set, without requiring data duplication or pre-aggregation.
The other options are not correct because:
* A. Dynamic tiering: This service allows you to extend the SAP HANA in-memory database with disk-based tables that can store large volumes of warm or cold data. You can use dynamic tiering to reduce the memory footprint and cost of SAP HANA, while still maintaining query access to the disk-based data. However, dynamic tiering is not supported by SAP HANA, express edition, as it requires additional hardware and software components.
* D. System replication: This service allows you to create and maintain one or more secondary SAP HANA systems that are identical copies of a primary SAP HANA system. You can use system replication to ensure high availability and disaster recovery of SAP HANA, as the secondary systems can take over the role of the primary system in case of a failure. However, system replication is not supported by SAP HANA, express edition, as it requires additional licenses and configuration.
