Previous issue date: 2015-02-26 / M?quinas de redu??o de grafos, s?o tradicionalmente utilizadas na implementa??o de linguagens
de programa??o. Elas permitem executar programas (representados como grafos),
atrav?s da aplica??o sucessiva de regras de redu??o. A composi??o de servi?os web permite
a cria??o de novos servi?os web a partir de servi?os web j? existentes. BPEL ? a
linguagem padr?o para criar composi??es de servi?os web como fluxos de trabalho. No
entanto, o uso de BPEL para definir composi??es que usem outras tecnologias, al?m dos
servi?os web n?o ? imediato. Na maioria dos casos, quando opera??es que n?o fazem parte
do dom?nio dos servi?os web precisam ser executadas nas regras de neg?cio de uma empresa,
parte do trabalho ? realizado de forma ad-hoc. Permitir que opera??es oriundas de
diferentes tecnologias possam fazer parte de um mesmo fluxo de trabalho auxilia a cria??o
de fluxos de trabalho mais adequados ?s necessidades das organiza??es. Esta disserta??o
define uma variante da linguagem BPEL para a cria??o de composi??es com opera??es
de servi?os web, tarefas de big data ou opera??es definidas pelo usu?rio. O suporte a esta
linguagem ? dado mediante a defini??o de uma m?quina de redu??o de grafos extens?vel,
a qual permite a execu??o de programas definidos na linguagem proposta. Esta m?quina
? implementada como prova de conceito. A proposta deste trabalho ? avaliada mediante
a apresenta??o de resultados experimentais. / Graph Reduction Machines, are a traditional technique for implementing functional programming
languages. They allow to run programs by transforming graphs by the successive
application of reduction rules. Web service composition enables the creation of
new web services from existing ones. BPEL is a workflow-based language for creating
web service compositions. It is also the industrial and academic standard for this kind of
languages. As it is designed to compose web services, the use of BPEL in a scenario where
multiple technologies need to be used is problematic: when operations other than web
services need to be performed to implement the business logic of a company, part of the
work is done on an ad hoc basis. To allow heterogeneous operations to be part of the same
workflow, may help to improve the implementation of business processes in a principled
way. This work uses a simple variation of the BPEL language for creating compositions
containing not only web service operations but also big data tasks or user-defined operations.
We define an extensible graph reduction machine that allows the evaluation of BPEL
programs and implement this machine as proof of concept. We present some experimental
results.
