ANALYSIS OF DATA EXCHANGE METHODS BETWEEN SOFTWARE SYSTEMS

The article discusses architectures aimed at ensuring the interoperability of various software tools and the regular communication of data in their databases with each other. In addition, several types of data mapping and mapping are described for these architectures when implementing integration, and two methods, ETL and ELT, are taken as examples of data mapping, and each is compared separately. The architecture of each of them is explained and the principles of operation are explained, and the capabilities of each of them in different use cases are compared, and the speed, confidentiality, and situations in the processes of working with large and small amounts of data are separately highlighted.
