Databases relationships are quantified with the following categories:
• One-to-one relationships
• One-to-many relationships
• Many-to-many relationships
We’ll discuss each of these relationships and provide an example. If you think of a family structure when thinking about relationships, you’re ahead of the game. When you spend time alone with one parent, that’s a specific type of relationship; when you spend time with both your parents, that’s another one. If you bring in a significant partner and all of you—your parents, you, and your partner—do something together, that’s another relationship. This is identical to the bucket analogy. All those different types of relationships are like specific buckets that hold the dynamics of your relationships. In the database world, this is the data you’ve created.
What is that bucket analogy the write is talking about?
