学年制和学分制两种数据管理模型的比较

从数据元素的属性上分析，学年制的数据属性比较单一，学分制的数据属性具有多样性。数据属性的多样性，引发了信息传递形式的复杂化，也派生出一些数据概念。这一特点意味着学分制教务管理工作和学分制教务管理信息系统的设计比学年制复杂得多，同时也意味着在学分制下开发的教务管理信息系统也适合学年制的教学管理模式。将学年制和学分制数据流程图进行对比分析，学年制和学分制具有基本相同的数据构成和数据流向。这一特点意味着在学年制下开发的数据库系统经过适当的扩充后可延续到学分制。

The Data Management Model Comparison between School Year System and Credit System

The school year system data attribute is unitary while the credit system data attribute is multiplex by analyzing the data element attribute. The multiplicity of data attribute makes the form of information transmission complicated, also derives some data concepts. This characteristic means the credit system educational administration and information system design is much more complex than the school year system. The school year system and the credit system has the basic same data constitution and the data flows through comparison between data flow chart of the school year system and the credit system . That shows the database system based on the school year system continue for the credit system after the suitable expansion.
