How do you use the data of player information and baseball scores in a mobile application?

Using player information as master data is the correct approach because master data is essential for providing context and meaning to transactional data within a system. It typically includes key entities like customers, products, and in this case, players. Master data is more static and does not frequently change, whereas transactional data reflects ongoing transactions that might change rapidly over time, such as game scores and player performances.

In this context, player information is foundational for understanding both the transactional events (like scores) and analytics that might be derived from the games played. When a mobile application retrieves or presents baseball scores, it must relate those scores to the corresponding player information. Thus, the player data serves as the primary reference point or anchor, making it essential to categorize it as master data.

In scenarios where both player information and scores were considered transactional data, there would be confusion, as transactions typically involve dynamic data that changes with each game played, whereas player information remains more constant over time. This distinction clarifies why the player information is categorized as master data in the application.
