功能：该数据库可以对比赛的信息，球员的信息，球队教练信息以及球员在比赛中的表现进行查询。有一个存储过程，可以显示特定球员的球员信息和球员平均数据。有一个触发器，删除球员信息的同时可以删除球员数据。有一个游标，当查询球员数据时显示MVP。有一个存储过程，可以查询特定位置上的球员数据排名。有一个触发器，可以识别用户等级，在更新数据的时候，若等级不够，则无法更改。有一个存储过程，可以记录用户喜好。

心得体会：该程序数据库的表结构科学，关系模式清晰，主键和外键使用正确，用SQL语句能完成一些基本的需求功能。功能明确，涵盖了用户所需要的功能，在此之上也有创新，增加的用户等级识别功能和记录用户喜好功能使程序更人性化，更符合用户的使用习惯。

遇到的问题：该数据库程序没有一个便于用户使用、易于操作的窗口程序。

解决办法：用JDBC把SQL SERVER与JAVA连接开发一个窗口程序。
