To answer this question, we need to understand the concept of data traps and the different types of relationships between entities in a database.
The illustration shows two entities connected by a line with parallel lines on either side. This represents a parallel relationship between the two entities.
Let's go through each option to understand why it is correct or incorrect:
Option A) Bridge - This option is incorrect because a bridge relationship is represented by a line connecting two entities with a diamond shape in the middle, indicating that the relationship is resolved through a bridge entity.
Option B) Connection - This option is incorrect because a connection relationship is typically represented by a line connecting two entities without any specific shape or symbol.
Option C) Parallel relationship - This option is correct because the illustration shows two entities connected by a line with parallel lines on either side, indicating a parallel relationship between the entities.
Option D) Many-to-many relationship - This option is incorrect because a many-to-many relationship is typically represented by a line connecting two entities with crow's feet symbols on either end, indicating that multiple instances of one entity can be related to multiple instances of another entity.
Therefore, the correct answer is option C) Parallel relationship. This option is correct because the illustration represents a parallel relationship between the two entities.
