Caracterização dos Dados trocados entre serviços web e provedores de serviços

This paper approaches the characterization of data types that are exchanged between web services and service providers. WSDL (Web Service Description Language) files, that represent the interface for the services stored in a service provider, were obtained from the Web and their contents were statistically analyzed. The methodology to reach the desired characterization consists in the collection and analysis of the 926 WSDL valid files. The results from this study should help the workload characterization of a service-oriented architecture with QoS support as well as to build web services with different behaviors and goals. From the obtained data the percentage of each data type (such as, String, Boolean and Float), the percentage of occurrence of complex and simple types as well as the characterization of WSDL file sizes, are all highlighted in this paper.
