To answer this question, you need to understand the concept of databases and data management.
Option A) Schema - This option is correct because a schema is a collection of named objects, such as tables, views, indexes, and relationships, that are organized into a logical structure within a database.
Option B) Table - This option is incorrect because a table is just one type of named object that can be included in a schema. While tables are commonly used to store and organize data, a schema can contain other objects as well.
Option C) Alias - This option is incorrect because an alias is not a collection of named objects. Instead, it is a temporary alternative name given to a table or column in a database query for convenience or to resolve naming conflicts.
Option D) Both a & b - This option is incorrect because the correct answer is A) Schema. While a schema can contain tables, the term "schema" encompasses a broader concept of a collection of named objects within a database.
Therefore, the correct answer is A) Schema. This option is correct because a schema is a collection of named objects within a database.
