Introduction to Car Racing Example

The car racing dataset is a well-structured, relational schema commonly used in Oracle AI Database demonstrations and tutorials. It provides a realistic and relatable context that models the world of competitive car racing, such as Formula 1.

The dataset is designed to illustrate fundamental database concepts, including entities, relationships, and normalization, with emphasis on relational integrity and core SQL operations.

Primary Entities and Relationships

The schema is comprised of four main tables, each representing a key component of the car racing domain:

Table 1-2 Primary Entities and Relationships of the Car Racing Example

Table Description Key Columns Relationship
team Racing teams information team_id (PK), name (unique), points 1:N with driver
driver Race car drivers driver_id (PK), name, points, team_id (FK) N:1 to team; N:N to race via map
race Race events race_id (PK), name, laps, race_date, podium N:N with driver via map
driver_race_map Driver participation in races and results driver_race_map_id (unique), race_id (FK), driver_id (FK), position N:1 to driver, N:1 to race

Table Descriptions

  • team: Contains information for each racing team. Each team is uniquely identified by team_id and has a unique name.

  • driver: Represents each driver, including personal details and a foreign key reference (team_id) to their associated team.

  • race: Documents each race, with columns for the race name, number of laps, and the date it took place. Every race has a unique race_id.

  • driver_race_map: A junction (or mapping) table that connects drivers to races. It records each driver's participation in a particular race and the position (finishing place) they achieved.

Data Model Overview

The schema embodies several key relationships:

  • One-to-Many (1:N): Each team can have multiple drivers. Enforced via the foreign key in the driver table to the team table.

  • Many-to-Many (M:N): Drivers can participate in multiple races and each race can feature multiple drivers. Captured by the driver_race_map table, which links driver and race.
