In view of the widespread problems like syntax heterogeneity and semantic heterogeneity in the service-oriented tool integration, this paper proposes a new data interaction manner and gives a detailed description of its implementation method and related technology. The manner's syntax definition is based on JSON format and it also takes an advantage of general vocabulary to handle the problem of semantic heterogeneity. At last, we implement the manner in an actual case of the integration of common software development tools, encapsulating tool's function as service. The experimental results show that the design of data interaction manner can well solve the problems mentioned above, thus provides good data interaction base for tools integration.
