Single Table

In a database management system, a single table is designed to obtain data of heterogeneous items. A single-table design with DynamoDB resolves the issue of raising multiple requests for the relevant data of an entity.

Question

**Latest Scores from the Japanese Baseball League**

Here is a table that displays the latest scores from the Japanese Baseball League, structured as (Team, Day, Opponent, Runs):

| Team | Day | Opponent | Runs |
|----------------|---------|-----------|------|
| Dragons | Sunday | Swallows | 4 |
| Tigers | Sunday | Bay Stars | 9 |
| Carp | Monday | Dragons | 10 |
| Hawks | Monday | Giants | 7 |
| Buffaloes | Tuesday | Tigers | 2 |
| Lions | Tuesday | Giants | 0 |
| Bay Stars | Friday | Tigers | 2 |
| Golden Eagles | Friday | Swallows | 5 |

**Database Query Example**

The query below is run on this data to find pairs where a team’s opponent matches another team’s opponent and the teams are different.

```sql
SELECT S1.Team, S2.Team
FROM Scores S1, Scores S2
WHERE S1.Opponent = S2.Opponent AND S1.Team <> S2.Team;
```

**Exercise: Identify a Valid Tuple**

Based on the query results, identify a valid tuple from the options below:

- a. Lions, Golden Eagle
- b. Golden Eagle, Buffaloes
- c. Hawks, Lions
- d. Bay Stars, Hawks

By evaluating the data and the query, you can determine which option is correct. Consider cross-referencing the Opponent values to see which teams faced the same opponents on different days.

**Explanation of Results**

- Option (c) **Hawks, Lions**: Both "Hawks" and "Lions" have "Giants" as their opponent.

So, in this case, option (c) is the correct answer.
