The principles of building information systems based on service-oriented architecture are considered. The advantages of using this architectural approach, as well as a model of the component composition of the system, are described. A description of various technologies for building software using a service-oriented approach based on web services is given. The main limitations of using the CORBA technology standard for writing distributed applications are determined. The technology of building web services based on the SOAP data exchange protocol is described in the context of using the ESB service bus for the interaction of heterogeneous services in a single information system. The architectural style of microservice organization of distributed software is considered as a way to increase the granularity of the system in order to ensure the best scalability and fault tolerance of the system. Methods for constructing the mathematical support of web services for distributed schematic CAD systems for calculating the influence of external influences (changes in temperature, radiation, etc.) on all output functions of the simulated circuit are presented. Parameters of two-terminal type R, L, and C and transmission parameters of dependent current or voltage sources controlled by potential or current variables are taken as variable values of the components. |
