To answer this question, we need to understand the concept of mapping a 1:1 relationship to a database table.
Option A) Transparent - This option is correct because when we map a 1:1 relationship to a database table, it is done in a way that is transparent to the user. This means that the relationship is represented in a straightforward and easily understandable manner, without any additional complexity or confusion.
Option B) View - This option is incorrect because a view in a database is a virtual table that is derived from the data stored in one or more tables. It is not specifically related to mapping a 1:1 relationship.
Option C) Cluster - This option is incorrect because clustering in a database refers to the physical arrangement of data on disk to optimize data retrieval. It is not directly related to mapping a 1:1 relationship.
Option D) Pooled - This option is incorrect because pooling in a database refers to the concept of reusing resources (such as database connections) to improve performance. It is not directly related to mapping a 1:1 relationship.
The correct answer is A) Transparent. This option is correct because mapping a 1:1 relationship to a database table is done in a way that is transparent and easily understandable to the user.
