The SAP Web IDE for SAP HANA graphical editor for Core Data Services (CDS) data models allows you to specify the following elements12:

• Entity: An entity is a CDS artifact that defines a data structure with attributes, keys, and associations. An entity can be mapped to a database table or view, or it can be used as a source for another entity or a calculation view. You can create an entity by dragging the entity icon from the palette to the canvas, and then defining its properties and attributes in the properties panel.
• Context: A context is a CDS artifact that defines a namespace for other CDS artifacts, such as entities, views, types, or associations. A context can be used to organize and group related CDS artifacts, and to avoid name conflicts. You can create a context by dragging the context icon from the palette to the canvas, and then defining its name and description in the properties panel. You can also add other CDS artifacts to the context by dragging them from the project explorer or the palette to the context node in the canvas.
• Association: An association is a CDS artifact that defines a relationship between two entities, based on a join condition. An association can be used to navigate from one entity to another, and to filter, aggregate, or project data from the target entity. You can create an association by dragging the association icon from the palette to the canvas, and then connecting it to the source and target entities. You can also define the cardinality, join condition, and exposed attributes of the association in the properties panel.

The other options are not correct because they are not elements that can be specified with the SAP Web IDE for SAP HANA graphical editor for CDS data models. A synonym is a database object that provides an alternative name for another database object, such as a table, view, or procedure. A synonym is not a CDS artifact, and it cannot be created or edited with the graphical editor. A procedure is a database object that contains a set of SQL statements that perform a specific task. A procedure can be created or edited with the SQL editor, but not with the graphical editor. A procedure can also be exposed as a CDS artifact, but it cannot be specified with the graphical editor. References:

 When a user is dropped with the “cascade” option, the user and all the objects owned by the user are deleted from the database. However, the objects that are owned by other users, or on which other users have privileges, are not affected by the drop command. The privileges granted to or by the dropped user are also revoked automatically. Therefore, the objects on which other users have privileges are not dropped, and the objects owned by other users are not dropped12.

The other options are not correct because they are not the consequences of dropping a user with the “cascade” option. The objects on which other users have privileges are not dropped, because they are not owned by the dropped user, and they may still be needed by the other users. The objects owned by other users are not dropped, because they are not related to the dropped user, and they may have dependencies or references to other objects. References:

 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.
