摘要: Recently, a lot of interest has been shown in SOA (Service Oriented Architectures). In these systems, there are multiple services each with its own code and data, ability to operate independently partners. particular, atomic transactions two-phase commit do not occur across because this necessitates holding locks while another service decides the outcome transaction. This paper proposes number seminal differences between data inside sent into space outside boundary. We then consider objects, SQL, XML as different representations data. Each models strengths weaknesses when applied The concludes that strength one area is derived from essential characteristics underlying weakness other area.
