## Dataset

* **Source**: [Kaggle – NBA Database](https://www.kaggle.com/datasets/wyattowalsh/basketball/data)

* **Original form**: \~20 CSV files (games, teams, players, etc.)

* **Table used here**: **`GAME`** – one row per game with results for both teams.

| Column           | Example            | Notes                |

| ---------------- | ------------------ | -------------------- |

| `GAME_DATE`      | 1949‑11‑02         | DATE                 |

| `TEAM_NAME_HOME` | "Detroit Pistons"  |                      |

| `TEAM_NAME_AWAY` | "Boston Celtics"   |                      |

| `WL_HOME`        | `"W"` / `"L"`      | Result for home team |

| `WL_AWAY`        | `"L"` / `"W"`      | Result for away team |

| `SEASON_ID`      | `"S2019"`          | Kaggle’s season code |

| `SEASON_TYPE`    | `"Regular Season"` | filters out playoffs |

## Import workflow

1. **Download CSVs** from Kaggle.

2. **Oracle SQL Developer ▶ Tools ▶ Import Data** → target table `GAME`.

3. Repeat for each CSV or use the wizard’s batch mode.

*(On a fresh Oracle 21c XE install the whole import fits comfortably in the default USERS tablespace.)*
