Query JPA Repository With Single Table Inheritance Subtypes

JPA provides various strategies for handling inheritance in Java-based applications, including single table inheritance where data of all subtypes is stored in a single table. Using annotations like @Inheritance, @DiscriminatorColumn, and @DiscriminatorValue, developers can configure this strategy, enabling easier querying of subtypes with JPA repositories. The tutorial covers setting up repository classes, persistence configuration, and using custom queries to filter subclass data.
