| 摘要: |
| 为包括数据库在内的信息系统提供长期进程模型是一项很重要而迫切的工作．本文首先介绍了使用具有通讯机制和时间表达能力的Ｐｅｔｒｉ同来模拟社会现象中长期行为的概念──Ｓｃｒｉｐｔ．然后阐述了如何用语义数据模型来描述这样的概念结构并略述了实现中的一些技术问题． |

| Abstract: |
| There is a great need in many enterprises for a superior model to serve the long term processes of information systems containing database. This paper first introduces modified Petri nets with communication mechanism and time expression to model long term behavior of social systems. Then it elaborates how to express the structures of this concept by using semantic data models and briefly discusses some technical problems for the purpose of implementation. |
| Key words: Long term process,entity,inheritance,communication,concurrency, decision making, synchronization |
