TUML: A Method for Modelling Temporal Information Systems

Time is a very important aspect of the real world. The importance of time in database applications has led to work on the extension of existing database technologies in order to handle time efficiently. Nevertheless, little work has been done in the area of temporal application development methods. In this paper we present the Temporal Unified Modelling Language (TUML) method. The TUML method extends the Unified Modelling Language (UML) with the temporal semantics defined in the TAU Temporal Object Model and the process of the Booch method to enable the capturing of the temporal semantics of information during information system development.
