public class DataAccessException
extends RuntimeException

Exception thrown when there are issues accessing or manipulating data in repositories.

This exception serves as a wrapper for various data-related errors that might occur during repository operations, such as: - File I/O errors when reading from or writing to persistent storage - Data format errors when parsing stored data - Consistency errors when data violates integrity constraints - Network errors when accessing remote data sources

By using this exception consistently across repositories, the application can handle data access errors in a uniform way in higher layers.
