Semântica das Mensagens que Constituem as Interfaces dos Três Principais Elementos da Meta Arquitetura Alana

Resumo

In this paper, we describe the Alana meta architecture, whose model encloses two major purposes: 1) to integrate the transaction feature to an object oriented programming language, and 2) toallow the extension and simplify the use of ATMs, fitting itself in the generic tools line. This meta architecture combines four paradigms, as follows:object oriented programming, concurrence,persistence and transaction. We believe that the presentation task of this meta architecture becomes difficult because this diversity of paradigms. Thus, toattempt make easier its explanation, we decided to describe how this meta architecture works by the interface semantic of their three major elements. For this, we classified their messages in three groups in accordance to function: 1) interaction messages; 2)persistence messages; and 3) global and local atomicity messages. For each group, we presented the behavior of these messages received by elements ofmeta architecture.
