Analyzed the current state of the Application Programming Interface (API) calls to cloud database management systems. The expediency of creating tools to reduce the time for servicing such requests and the effective synchronization of the local and cloud databases has been established. The main features and principles of data replication are clarified. The expediency of using the counter of generations in the replication process instead of the system timer is justified. An asynchronous method of accelerated servicing for API calls to cloud database management systems is proposed by using a synchronization accumulative table and registering changes in databases using a two-stage set of generations. A library that provides the implementation of asynchronous API queries for the Salesforce cloud management system has been developed. The library can be used in any Ruby on Rails application. The evaluation of the benefits for the proposed solutions in the test case was carried out. The results of the test studies confirm the minimization of the service time for API calls to the cloud database management systems based on the proposed asynchronous method.
