Abstract

Database systems for real-time applications must satisfy timing constraints associated with transactions, in addition to maintaining data consistency. Recently, interests in object-oriented databases have been growing for non-traditional applications of database systems, and several real-time applications are being developed using an object-oriented paradigm. The object-oriented approach seems promising for developing complex real-time database applications. However, it is not clear whether object-oriented database systems would be superior than relational database systems for supporting real-time applications. In this paper, we address issues that must be investigated in order to design and develop an object-oriented database system for real-time applications. Also, we present a model that integrates features for scheduling real-time transactions with the traditional object-oriented database model.<>

开发面向对象的实时应用数据库系统的问题
用于实时应用程序的数据库系统除了维护数据一致性之外,还必须满足与事务相关的时间约束。最近,对于数据库系统的非传统应用,对面向对象数据库的兴趣正在增长,并且正在使用面向对象范例开发几个实时应用程序。面向对象的方法对于开发复杂的实时数据库应用程序似乎很有希望。然而,在支持实时应用程序方面,面向对象数据库系统是否优于关系数据库系统还不清楚。在本文中,我们讨论了为了设计和开发一个面向对象的实时应用数据库系统而必须研究的问题。此外,我们还提出了一个集成了实时事务调度特性和传统面向对象数据库模型的模型。
