Database design

Defining the system data model early on will clarify how data will flow among different components of the system. Also you could draw an ER diagram using the diagramming tool to enhance your design...

Structured Data

Users
- id (string, Primary Key)
- username (string, unique)
- email (string, unique)
- password_hash (string)
- favorite_teams (array of strings)
Sports
- id (string, Primary Key)
- name (string)
- type (string) - e.g., team vs. individual sports
Games
- id (string, Primary Key)
- sport_id (string, Foreign Key referencing Sports)
- team1_id (string, Foreign Key referencing Teams)
- team2_id (string, Foreign Key referencing Teams)
- start_time (datetime)
- status (string) - e.g., ongoing, finished, scheduled
Players
- id (string, Primary Key)
- name (string)
- team_id (string, Foreign Key referencing Teams)
- position (string)

Unstructured Data

Stats
- Player performance data (e.g., points scored, assists, etc.) could be logged in a flexible structure, possibly using JSON format:
{ "player_id": "123", "game_id": "456", "stats": { "points": 20, "rebounds": 5, "assists": 8 }}
Events
- Similar to stats, events could vary in structure depending on the type:
{ "event_id": "789", "game_id": "456", "event_type": "score", "timestamp": "2023-09-20T12:00:00Z", "player_id": "123", "description": "Player 123 scored a 3-pointer"}

Indexing Strategy

Users Table (RDBMS)
- Index on email:
  - Purpose: Fast lookup during user authentication and account management.
- Index on username (if applicable):
  - Purpose: Accelerate searches if username searches are expected.
Sports Table (RDBMS)
- Index on type:
  - Purpose: Efficient filtering and searching of sports by type (e.g., team sports, individual sports).
Games Table (RDBMS)
- Index on sport_id:
  - Purpose: Enable quick joins and filtering of games associated with a specific sport.
- Index on team1_id and team2_id (if applicable):
  - Purpose: Optimize lookup for games involving specific teams.
Players Table (RDBMS)
- Index on team_id:
  - Purpose: Streamlines searches for players on a specific team, especially useful for team management interfaces.
- Index on position:
  - Purpose: Enables efficient queries for players by their positions (e.g., forwards, defenders).
