In Oracle OAC, which of the following options is NOT a method to create a data set?

In Oracle Analytics Cloud (OAC), the methods for creating a data set primarily revolve around connecting to various data sources. The options provided relate to commonly used methods in OAC for creating datasets.

• Utilizing a connection is a standard approach whereby OAC connects to different data sources like databases or applications, allowing users to pull data directly into OAC.

• File is another method wherein users can upload a file (such as CSV, Excel, etc.) directly to create a dataset. This allows users to quickly incorporate data that may not reside in a connected database.

• Creating a dataset using a subject area involves selecting from predefined logical data models that organize data in a way that makes it easier to analyze. Subject areas are typically constructed based on underlying connections to databases and the available data in those databases.

However, the concept of a database schema, while important in understanding the organization of data within a relational database, is not a direct method for creating a dataset in OAC. A database schema refers to the structure that defines how data is organized in a database but does not represent a method for extracting or creating datasets in analytics tools like OAC.

Thus, identifying a database schema as not being a method to directly create a dataset is accurate, as creating datasets
