SAP HANA - Views

Explanation
Attribute View, Calculation View, and Analytic View are the three types of views that can be created under the packages. Attribute View is used to define the structure and attributes of a business entity, Calculation View is used to combine data from multiple sources and perform calculations, and Analytic View is used for complex analysis and reporting purposes. These views provide different functionalities and can be used to meet various business requirements within the packages.

Explanation
Attribute views are used to select only a few fields from a table for reporting purposes. This allows users to focus on specific attributes or characteristics of the data without having to consider all the fields in the table. Additionally, attribute views can also be used to join tables of the same type, enabling the combination of related data from multiple tables into a single view. This can be useful for creating comprehensive reports or analysis that require data from different tables within the same category or entity.

Explanation
Analytic views can be created with Tables and Attribute views. Analytic views are used in SAP HANA to provide a business-oriented view of the data. They allow users to perform complex calculations and aggregations on the data stored in tables and attribute views. By combining the data from both tables and attribute views, analytic views enable users to gain insights and make informed decisions based on the data analysis.

Explanation
The icon used to show an attribute view is represented by multiple squares. This could indicate that the attribute view contains multiple attributes or characteristics that are being represented. Each square could represent a different attribute, making it easier for users to identify and understand the content of the attribute view.

Explanation
Attribute views can be created under a package. A package is a container that holds related objects together. Creating attribute views under a package allows for better organization and management of the views. It also helps in maintaining a clear structure and hierarchy within the database. By creating attribute views under a package, it becomes easier to locate and access them when needed.

Explanation
Open Data Preview can be used to see the tabs for raw data, distinct values, and analysis of a table or a view. This feature allows users to preview the data in a structured format, view distinct values in columns, and perform analysis on the data. It provides a comprehensive view of the data and helps in understanding its content and structure.

Explanation
The correct answer is _SYS_BIC. This is because views are saved under the schema _SYS_BIC in the database. The _SYS_BIC schema is specifically used for storing business intelligence content, including views, in the database.

Explanation
User access can be limited for packages, SQL objects, and system privileges. This means that users can be restricted from accessing or modifying specific packages, SQL objects (such as tables, views, or procedures), and system privileges (such as the ability to create or modify users, roles, or permissions). By limiting access to these elements, organizations can ensure that users only have access to the necessary resources and functionalities, improving security and preventing unauthorized actions.

Explanation
This statement is true because in a database management system, a schema is a collection of database objects (such as tables, views, indexes) that are logically grouped together and owned by a specific user. Each user or login ID in the system can have their own schema, which allows them to have their own set of objects and control over their own data. Therefore, only one schema is created for one login ID.

Explanation
Analytic privileges can be created under a package. A package is a container that holds related objects such as analytic views, attribute views, calculation views, and other objects. It provides a way to organize and manage these objects together. By creating analytic privileges under a package, it ensures that the privileges are applied specifically to the objects within that package, allowing for better control and management of access to data and analytical capabilities.

Explanation
In programming, packages are used to organize and group related classes and interfaces. A package can contain other packages, which allows for further organization and hierarchy within the code structure. This feature is commonly found in programming languages such as Java. Therefore, the statement that a package can be created under another package is true.

Explanation
A package name is always in lower case because in Java, package names are case-sensitive and it is a convention to use lowercase letters for package names. Using uppercase letters can lead to confusion and errors when importing or referencing the package in the code. It is important to follow this convention to maintain consistency and readability in the code.
